Important preface. Since Samsung has only prototypes, it is impossible to evaluate the photos of these devices, as well as conduct a full-scale comparison with other devices. At the end of May, when commercial samples appear, we will update this first glance and share a large number of pictures. Also on Friday, quite a lot of test pictures from the prototype will be added here, they will give you an idea of \u200b\u200bthe capabilities of the camera - I think it will be completely competent. IN this moment Noise are observed in a number of shooting modes, the picture happens soy. It is promised to fix the commercial version. Remember this when you evaluate certain pictures.

Positioning

Samsung is trying to emphasize that the Zoom ruler is a separate direction in development. smart devices, sort of hybrid cameras with smartphones. The first generation of S4 Zoom did not produce any furor - the chamber came out in June 2013, became a niche product. But even then the positioning of this device was clear - this is a camera for those who need good snapshots that are possible in different conditions, the presence of zoom, which has become possible thanks to the built-in optics. The appearance of the Zoom ruler to some extent questioned the existence of such a product as Galaxy Camera - why buy a smart camera on Android, which can not call if you can purchase a smartphone with similar characteristics, that is, a device that combines two directions at once.

Samsung Galaxy Camera 2.

SAMSUNG GALAXY S4 ZOOM

Many consumers say that the quality of the pictures is very important for them, but under this quality everyone understands something. The vast majority of people believe that the photos should look excellent on the device screen, how these pictures look on the laptop or television screen, do not care. Yes, and prints pictures today a very small number of people.

Phone manufacturers constantly improve the quality of the photo models, most common solutions use the Sony Exmor module of a generation, they are considered the best. Optics plays a role, but in conditions of a limited height of the smartphone housing, it is not possible to embed normal lenses. The Zoom line was created as an intermediate product between cameras and smartphones, that is, a device that takes the best from two worlds. Perhaps such a hybrid will be interesting to those who shoot a lot, does not want to carry two devices with them and satisfy the quality of the pictures of modern phones, but it is still eager to get the opportunity to use the optical zoom. For cameras, the presence of zoom is at all the great thing that creates new features for pictures, sometimes you cannot go closer, but you want to make a snapshot - there are many situations, from the zoo to the photo of the other side of the road or details of the building.

The number of those who are interested in photographs and does not have its own permanent photo, very small. The number of mirrorless cameras, which does not have built-in NFC / Wi-Fi today, is also rapidly reduced - to transfer instantly pictures to the smartphone for a long time no longer represents a challenge. Therefore, the existence of such products as Galaxy K Zoom causes questions, they are definitely not needed by a mass market, too expensive for him. For enthusiasts, this is an interesting toy for ordinary consumer - A good, but expensive camera, replacing the soap. There are scenarios in which such a solution wins (for example, a reportage shooting and instant publication of snapshots on the network), but they are extremely few. Also, as the first S4 Zoom was a niche solution for all, and the second generation looks exactly the same. It is possible that some miracle it can become widespread, but there is no serious prerequisites for this today.

Design, dimensions, control elements

The ideology of this device completely repeats as such for the predecessor - S4 Zoom. A solid massive case - 137.5x70.8x16.6 (20.2) mm, weight 200 grams. Galaxy S4 Zoom size was less - 125.5x63.5x15.4 mm, weight 208 grams. But on the other hand, both products are such that they can be put in the pocket of jeans, but they will hardly drink. This is a typical size of a small soapbox, and not a smartphone at all.

In comparison with Nokia 1020

I repeat my thought, expressed a year earlier - the Zoom ruler is positioned closer to smartphones, this is the idea of \u200b\u200bmarketers that is harmful. The modern smartphone should easily be placed in the pockets of clothing, and not only the top.

On the back of the device, you can see the lens, there are no rotary rings, all control is automated - the lens itself is shifted when the camera is activated. On the right side - a paired volume adjustment key, just below - the on / off button, and below the camera key. It is stupid, but it is impossible to activate the shooting to the camera, it was forbidden due to the concern of damage to the lens during accidental disclosure in your pocket or bag. It is logical, but still you expect that such an option was to foresee. Interestingly, in the menu you can choose the activation of the shooting when the device is turned on - that is, it turns out that it is still coming to the same, with which they fought, but the camera button is still not involved.

The speaker is visible near the lens, the left is xenon flash. On the left side is a card slot microSd memory, It is covered with a plug.

The back cover of the device is made under Galaxy S5, but the material is completely different, it is ordinary plastic. Nic protective properties The body does not possess, no special coating on it is applied.

In comparison with Samsung Galaxy S5

The cover is easy enough to open, inside you will see the battery, under it - a slot for a microSIM card. There are no complaints to the quality of the assembly, everything is quite good, which, however, typically for Samsung.

On the front surface you can see the central key, it is mechanical, on the sides of the two touch buttons. Near the dynamics - front 2 megapixel camera, as well as the approximation sensor.

On the upper end - a 3.5 mm connector for a headset or headphones, there is one of the microphones, the second in the lower end, there is a connector for charging a microUSB.

Display

The screen diagonal is 4.8 inches, and the resolution is 1280x720 points, which is slightly distinguished by the device from flagships having FullHD resolution. On the other hand, this is quite enough for comfortable work, no complaints of the quality of the SuperMoled screen does not cause. Also in Galaxy S5, there is a maximum power saving mode here, which uses gray on the screen, which allows you to achieve more work hours. Also present a large number of settings, you can choose a color temperature, pick up both brightness and saturation of colors under your perception. Samsung gives maximum capabilities to manage screens in their devices, but by default settings are given a very bright, acid picture that may not like. All in your hands, you can change how the display will work. In the sun, the screen is visible not bad.

Battery

The phone has a battery 2430 mAh Li-Ion. When used only as a camera with a 3G / 4G-module, the device is able to work for a couple of days and make three hundred photographs. If you actively use the component of the smartphone - to call, write messages, communicate in social networksIn the evening of the first day, the device will ask for recharging. This is a little more than the current flagships, but still not so good, especially for a hybrid device. If this is an addition to your smartphone, then the working time is acceptable if this is the main device, then it is clearly low - although it is not knocked out of what is in the market from other manufacturers or Samsung.

USB, Bluetooth, Communication Features

Bluetooth. Bluetooth 4.0 version (LE). When transferring files to other devices with support for this technology, Wi-Fi 802.11 n is activated, and the theoretical transmission rate is about 24 Mbps. Checking transmit 1 GB file showed the maximum speed of about 12 Mbps within three meters between devices.

The model supports various profiles, in particular, Headset, Handsfree, Serial Port, Dial Up Networking, File Transfer, Object Push, Basic Printing, SIM Access, A2DP. Working with headsets does not cause any questions, everything is forgiven.

USB connection. USB version - 2, data transfer rate is about 25 MB / s. With a USB connection, the device is recharged.

The MicroUSB connector also supports the MHL standard, which means using a special cable (you can purchase it in electronics stores), you can connect the phone to the TV (to HDMI-output). In fact, the standard and describes the ability to connect via microUSB to HDMI. Such a solution looks preferable than a separate minihdmi connector on the housing.

For GSM networks provided EDGE class 12.

Wi-Fi. The 802.11 A / B / G / N standard is supported, the workshop is similar to that for Bluetooth. You can remember the selected networks, automatically connect to them. It is possible to configure the connection to the router to one touch, for this you need to press the key on the router, as well as activate the same button in the WPA SecureEasySetup menu. From additional options, it is worth noting the setup wizard, it appears with a weak or disappearing signal. You can also configure Wi-Fi to schedule.

Wi-Fi Direct. The protocol that is intended to replace Bluetooth or start competing with its third version (it also uses Wi-Fi versions n to transfer large files). On the menu Wi-Fi settings Select the Wi-Fi Direct section, the phone begins to search for devices around. Select the desired device, activate the connection on it, and voila. Now in the file manager you can view files on another device, as well as transmit them. Another option is to simply find devices connected to your router, and send the necessary files to them, it can be made from the gallery or other partitions of the phone. The main thing is that the device supports Wi-Fi Direct.

NFC.. The device contains NFC technology, it can be used with various additional applications.

S beam. Technology that allows you to send a few gigabyte size to another phone in a few minutes. In fact, we see in S Beam a combination of two technologies - NFC and Wi-Fi Direct. The first technology is used to bring and authorize the phones, but the second is already to transfer the files themselves. A creative recycled way to use Wi-Fi Direct is much easier than using connections on two devices, file selection and so on.

Memory, memory cards

In the phone 8 GB of internal memory, about 5 GB is available to the user. Also supported memory cards up to 64 GB.

The amount of RAM is 2 GB, after loading is free of 900 MB. This is enough for all applications.

Hardware platform

This device is the second from Samsung, where the 6-core Exynos 5260 processor is used, the first became the first Galaxy Note. 3 neo. Let me remind you that the performance of Neo in comparison with the usual Galaxy Note 3 on Exynos did not affect the imagination, and the time of work was not very different. Exactly the same situation in Galaxy K, the performance is noticeably lower than in Galaxy S5, but at the level of ordinary smartphones of the current generation. Not the fastest, but it is also impossible to call it slowly - the question is exclusively in what you are accustomed to.

In the processor 4 of the slow kernel A7 with a frequency of up to 1.3 GHz, two fast A15 with a frequency of up to 1.7 GHz.

Below you can see the results of synthetic tests.

Software Features - Software for working with photos

I do not know why they decided to give up the name of the Galaxy S5 Zoom (in some menus it is present, as before), but software stuffing (Android 4.4.2) is almost a complete copy of Galaxy S5. Repeat all the features does not make sense, especially since this is done in a separate material. Let's talk about new chips associated with photography.

The editor of the pictures was renamed in the studio, they also added the ability to edit the video. It turned out quite pretty - the editor is rich in opportunities and closes the needs of the vast majority of users.

And here pro Annex Pro. Suggest Market is a completely different story, in it you can watch both photos of other people and lessons on how to remove this or that composition. It is curious that you can save individual lessons, they will appear on your list. But the main thing is that by clicking on the camera icon, you are in one touch, configure everything for shooting exactly in that way, as shown in the test picture. For example, removing the portrait, the camera will exhibit all optimal settings For this type of snapshot.

This program is not the first tutorial in photographs in phones, perhaps, for the first time something similar appeared about ten years ago in the CyberShot series from Sony Ericsson.But never got caught. There is a chip here, it is that you can not only read how to make such a photo, but also to try to do it right there. This increases the value of such a "textbook", and it is assumed that the tips will be much and you can upload new ones. In my opinion, this option can really be considered interesting, and I hope that other manufacturers will take it into service.

The application also contains a certain social component, your name is shown in the list (tied to Samsung Account), when publishing a photo you have rising levels. What advantages it gives you personally, while not very clear. But in the future something like this will be on all photo eating from Samsung, which work on Android.

It remains to say that it goes free along with this apparatus - the VINE service has prepared a special version of the application so that it involves the possibility of zoom when creating 6-second rollers. Traditionally, there is a subscription to 50 GB and for two years in Dropbox (for new users only). Up to 1 TB of place in Bitcasa for 3 months, which is not so interesting. In the Blurb application you get a $ 5 coupon for printing your photo album. The Fast Burst Camera application is free for 3 months (it must be downloaded), it allows you to make up to 30 shots per second. PICSplay Pro also is also free for 3 months, you will find about 200 filters in it. And finally, the Share Lens program to broadcast a real-time picture.

Camera - shooting capabilities

Focal lens distance - 4.4-44 mm, diaphragm - from 3.1 to 6.3. Tenfold optical zoom (in the previous model is the same). The camera module is not very expensive, it is a 1 / 2.3 inches bsi-matrix, exactly the same used in Sony Z1 / Z2. The presence of a normal lens is leveled by a small matrix, which is inherent in smartphones, not cameras, is the greatest drawback of this device. The maximum resolution of the picture is 20.7 megapixels.

The ISO value is from 100 to 3200. In most cases, the device seeks to put small ISO values, and it is correct. Also, I want to note separately that the device is not bad working out the white balance, which is unexpectedly for such a camera.

For most users, there is no point in manual mode Set the ISO value, in most cases the automation works out all true. The ISO remains 800, then the picture is well noticeable.

Of the curious innovations, it is worth noting separate focusing and exposure, you can click on the image on the screen, and then after focusing, select another section of the picture, which will be exhibited. An example of how it works can be seen in our.

But this is how the optical zoom function works, it is interesting in most situations, except for certain scenarios. The first and basic, maximum zoom cannot be used with smart modes, then the result becomes unpredictable.

The number of different shooting empties exceeds two dozen, you can choose the one that suits you.

Here are examples of photos in comparison with Galaxy S5.

More photos in this material will appear on Friday, do not forget to return to see various shooting options.

Video recording is supported in FullHD, it can be both 30 and 60 frames per second.

Impression

Sales of Galaxy K Zoom should start at the end of May-early June. The cost of this device will be 24,990 rubles, which is catastrophically, especially on the background galaxy prices S4 Zoom, which was at the time of starting sales of 19,900 rubles, and today this model costs about 12,000 rubles (4G-version), the usual version costs about 10,000 rubles (this is the price of this price at the time of writing this material).

What is due such a high price, I personally incomprehensibly completely. Attempt to attract this device closer to Galaxy S5? But in the company, on the contrary, they are trying to avoid their comparisons and dilute completely in different niches. It is clear that the cost of components in the Galaxy K Zoom is high enough, but it cannot be so high to justify a noticeable price increase compared to the previous generation device. Perhaps, Samsung decided that the weakening of the ruble plays a role, and therefore the cost for the niche product was changed.

In my opinion, there is no point in buying the camera for this money. She is simply indecent expensive. I do not say that for comparable money you can buy a mirror or mirrorless camera with replaceable optics, although it is possible. Exactly the same device from Samsung, but last year, is two times cheaper. Photo quality is comparable, only permission is distinguished, and the zoom is the same as optics. Of course, there will be a small number of those who chase for the novelty. But there will be very few such people. And the niche itself, in which Galaxy K Zoom plays, is very small. Expect some notable sales worth it, this product is definitely not for everyone. Shocking on the market from his exit will not happen, as it did not happen and a year ago for Galaxy S4 Zoom.

Links on the topic

Samsung Galaxy K Zoom is a new model in a family of devices designed to "combine a horse and tremble lan in one harness", that is, create a smartphone capable of completely replacing a compact digital camera. And this, as we understand perfectly well, is impossible without using the zoom lens.

SPECIFICATIONS SAMSUNG GALAXY K ZOOM

If the previous model - Galaxy S4 Zoom - essentially a phone budget classTo which the sake of the experiment screwed the camera with an optical zoom, then Galaxy K Zoom is a much more serious apparatus. In particular, it received a HD-resolution screen, a sufficient number of RAM and the Fast Exynos 5 Hexa processor, which will be written below.

Appearance and design features

In the front projection of Galaxy K Zoom, it is easy to confuse with any other Samsung smartphone, for example, with Galaxy S III: all the same smooth outlines, rounded corners, a hardware button "Home" under the screen ...

This illusion, however, is broken down, it is worth only to turn the phone back up: it turns out that it has a huge (on telephone standards) an integrated camera lens and xenon flash. The lens noticeably protrudes from the body of the apparatus, so the smartphone is at the table at an angle, and in jeans pocket it looks somewhat strange.

But in the hand of Galaxy K Zoom there is a better nowhere: a considerable thickness helps, and the ledge of the lens serves as a good focusing for the fingers. In this case, the front lens of the lens is not dirty, since in the folded state it is covered with "petals".

All side buttons are bored on the right face: there are dual volume keys, the power / lock button and the camera key. On the left side - slot for mICROSD cards And the loop for the strap.

Capacity galaxy battery K Zoom is 2430 ma-h. By the way, the cover of the device (covered, like the Galaxy S5, pupil pattern) fit very tight, so that I personally managed to open it only at the price of a broken nail.

Screen

Galaxy K Zoom is equipped with a 4.8-inch amoled screen with a resolution of 1280x720 points and the location of subpixels according to the Pentile scheme. Previously, the same screen was used in Samsung Galaxy S III. Unfortunately, it has almost all the "classic" disadvantages of the amoled screens of the previous generation. The color coverage of the screen is beyond the framework of the SRGB standard, which leads to excessive saturation and "poisonousness" of the paints. Add to this very noticeable color reproduction in the cold side - and you get the picture is not too pleasant for your eyes. By the way, in Galaxy K Zoom, unlike SGS4 and SGS5, there are no switchable color reproduction profiles (which in the terminology of Samsung are called "screen modes"), so that the rigus of the paint will not come out even with a great desire.

The maximum screen brightness is only 251 kD / m 2. The screen is noticeably dimly than the Galaxy S5 - it is clearly visible in the photo below:

Device name	White field brightness, cD / m 2	Black field brightness, cD / m 2	Contrast

LG G Pro Lite	328.28	0.52	631:1
LG Optimus G Pro	306.79	0.51	602:1

Camera

Without a doubt, the camera is a key feature of Galaxy K Zoom, its Raison D'être. The smartphone is equipped with a 20-megapixel matrix of BSI-CMOS form factor 1 / 2.33 ", which works in a bundle with a 10-fold optical zoom lens (which is the equivalent focal length of which is 24-240 mm). True, to shove such zoom into a smartphone, I had to sacrifice the luminosity, which is only F / 3.1 in a wide-angle position and F / 6.3 in the television. Therefore, oddly enough, when shooting in non-ideal conditions, Galaxy K Zoom provides the same quality as smartphones with smaller matrices, but more light-eyed optics. The smartphone is equipped with an optical image stabilizer, which will be quite by the way when shooting video from hand.

In the decomposed state, the lens markedly protrudes from the housing of the smartphone. Keep the machine when shooting quite convenient. Unlike the "ordinary" smartphones Samsung, Galaxy K Zoom is equipped with a separate button of the camera, which personally seemed to me unnecessarily "sobbed" (although it is possible that this feature of a specific test instance).

The camera interface is very close to those in Galaxy S5. The only major difference is that the K Zoom is present P (software), which allows manually to establish sensitivity and exposure. The device allows you to select different focus and exposure modes. In general, the possibilities for managing photographic parameters from Galaxy K Zoom exactly as much as in low-cost "soaps".

The smartphone relieves the video perfectly, the shooting of the rollers is maintained in fullHD resolution with the update frequency of 60 k / s. During video recording, zoom is possible.

The quality of photography Galaxy K Zoom as a whole corresponds to inexpensive compact cameras. Photos taken with good lighting, have excellent detail in the center of the frame, but the loss of sharpness is noticeable at the edges. In the extreme television, the situation is exacerbated by the fact that the aperture F / 6.3 initially lies beyond the diffraction threshold for the matrix of this size and permission, in other words - the lens is physically unable to resolve the matrix.

Of course, the presence of a 10-fold optical zoom makes Galaxy K Zoom more flexible in a photographic sense than any other smartphone. For example, these two frames were made from the same point in the lens wide-angle and television:

Disclinment and autonomy

Samsung Galaxy K Zoom is equipped with a very interesting EXYNOS 5260 processor, which boasts MALI-T624 graphics, two ARM Cortex-A15 kernels (1.7 GHz) and four Cortex-A7 cores (1.3 GHz). Interestingly, this processor supports HETEROGENOUS MULTI-PROCESSING (HMP) technology, which allows the use of kernels in any configuration, including all six simultaneously. This chip in combination with 2 GB of RAM demonstrates excellent performance and in benchmarks, even somewhat ahead of last year's Galaxy S4, in which 4 Cortex-A15 kernels and 4 Cortex-A7 kernels were used, but without HMP support.

In terms of autonomy, Galaxy K Zoom behaves like a typical Android smartphone: with active use it is enough for exactly one day with a small margin.

In the dry residue

SAMSUNG GALAXY K ZOOM is a smartphone that combines traditions and innovation. To "traditions" refers outdated screen and typical for samsung phones design. In the "innovation" graph, you can write a very smart 6-nuclear EXYNOS 5 Hexa processor and a chamber unique to the phone.

Without a doubt, Galaxy K Zoom is a niche device, but the smartphone is not devoid of a certain charm. At the very least, I would personally use them with pleasure. Even rather big sizes in some sense go to him: because of them, the device is perfectly in hand. Do not forget about the convenience of a 10-fold zoom lens with optical image stabilization.

5 reasons to buy samsung galaxy k zoom:

• excellent performance and high speed;
• camera with 10-fold optical zoom and optical image stabilization;
• good quality Video and the possibility of smooth zoom during shooting;
• xenon flash;
• the best combination of smart and photographic features On the market.

1 reason not to buy samsung galaxy k zoom:

• dubious screen quality.

The second and almost successful attempt to cross the compact camera and smartphone

A year ago samsung company He brought the world a hybrid of a compact camera and smartphone represented by the Galaxy S4 Zoom device. Unlike other solutions on the verge between smartphones and compacts used by a smartphone only as a display (Sony QX10 and Sony QX100), this attempt was their direct crossing, in which the camera and smartphone work side by side and without a friend can not. Despite the interesting idea, we could not name the realization of successful, since it observed a lot of flaws - both in terms of ergonomics and part of positioning. Let's see what mistakes take into account Samsung and what conclusions did.

Recall that in galaxy review S4 Zoom We decided to raise a little about unsuccessful design solutions when creating a device of this kind: Pseudo-camera form and unnecessary physical governments created for convenience, but in fact reaching the opposite effect. And simply looking at K Zoom, it is nice to note that some moments are significantly improved, and therefore, in terms of ergonomics, the camera is more adapted to everyday use. But first things first.

Appearance

	The lens traditionally reports its characteristics: 24-240 mm F / 3.1-6.3. Also in front are a xenon flash, autofocus backlight and speaker.
	From the display, there are practically no differences from Galaxy S5, except for sizes.
	From above there are power buttons, descent, as well as the volume of the volume adjustment that is responsible for the transfocation in the camera mode.
	From the bottom there are a slot plug for memory cards and an eyelet for a manual strap, which is diagonally opposite to the descent button, which is not always convenient. The microSD slot is deep in the housing, and even having thin fingers, you will have to try to "stick" in the slot.
	The right is the micro-USB connector (for charging and transferring data) and the microphone.

Screen

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface resistant to the appearance of scratches. Judging by the reflection of objects, the anti-glare properties of the screen is not worse than the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, we give a photo on which the white surface is reflected in the screens (left - Nexus 7, on the right - Samsung Galaxy K Zoom, then you can differ in size):

The screen at K zoom is even slightly darker (brightness by photographs 82 versus 85 at Nexus 7). Two of the reflected objects in the K Zoom screen is very weak, it suggests that there is no air gap between the layers of the screen. Note that the outer mineral glass in the case of screens with OLED matrix will perform a double protective function - from mechanical damage and from oxygen air, which is able to quickly oxidize organic LEDs. Best protection From diffusion of oxygen than mineral glass, as apparently, did not come up with, which restrains the development of truly flexible OLED screens. Due to the smaller number of boundaries (type of glass-air) with highly distinguished refractive ratios, the screens without air gap looks better in conditions of strong exterior illumination, but their repair in the event of a cracked exterior glass costs much more expensive, since it has to change the entire screen. On the outer surface of the Samsung Galaxy K Zoom screen there is a special oleophobic (fat-repellent) coating (very efficient, slightly better than Nexus 7), so traces from the fingers are removed significantly easier, and appear at less speed than in the case of conventional glass.

When displaying a white field into full screen and with manual control brightness, its maximum value was 245 cd / m², minimum - 4 cd / m². Despite the low value of brightness, good anti-glare properties contribute to the preservation of some readability even with bright daylight. It is also necessary to take into account the fact that in this case the smaller the white area on the screen, the brighter, that is, the actual maximum brightness of white areas will be almost always higher than the specified value. For example, when withdrawing white on half of the screen, the maximum brightness with manual adjustment increases to 260 kD / m². Low brightness mode without problems allows you to use the device even in complete darkness. It works automatic brightness adjustment over the light sensor (it is located to the right of the front loudspeaker). You can make adjustments to the operation of this function, moving the settings slider from -5 to +5 units. Next, for three conditions, we give the screen brightness values \u200b\u200bfor the three values \u200b\u200bof this setting - for -5, 0 and +5. In complete darkness in automatic mode, brightness decreases to 5, 8 and 12 kD / m², respectively (dark, but something can be seen), in conditions lit by artificial light of the office (about 400 lux), the brightness is set to 60, 120 and 200 kD / m² (just just), in a brightly lit environment (corresponds to the lighting clear day outdoors, but without direct sunlight - 20,000 LCs or a little more) - rises to 245, 345 and 345 kD / m². The last two values \u200b\u200bare greater than the maximum with manual adjustment, and such brightness should be enough to ensure some readability even in the sun. In principle, the result of the operation of the automatic brightness adjustment function corresponds to the expected. When reduced brightness, modulation appears with a frequency of 240 Hz. Figure below shows the dependences of the brightness (vertical axis) from time to time (horizontal axis) for several brightness setting values:

It can be seen that the modulation is practically absent on the maximum and close to it (the amplitude is insufficient for visual flicker distinguishability), but on medium and low brightness the relative modulation amplitude is high, so the flickering of the image can be seen in the test for the presence of a stroboscopic effect or simply with the quick eye movement . Depending on individual sensitivity, such flicker may cause increased fatigue.

This smartphone uses the Super AMOLED matrix - an active matrix on organic LEDs. The full color image is created using subpixels of three colors - red (R), green (G) and blue (B), but green subpixels are twice as much as possible as RGBG. This is confirmed by a microfotography fragment:

For comparison, you can familiarize yourself with the micrographic gallery of the screens used in mobile technology.

For such matrices, Samsung introduced the name Pentile RGBG.. Screen resolution The manufacturer believes on green subpixels, in two others it will be two times lower. The location and form of subpixels in this embodiment is similar to the option, for example, in the case of the Samsung Galaxy S3 screen. This version of Pentile RGBG is somewhat worse than new with rhombic subpixels, implemented, for example, in Samsung Galaxy S5. It is worse than the above notice of artifacts in the form of some irregularities of contrasting borders.

The screen is characterized by magnificary viewing angles, however, a light blue-green shade takes on a relatively large corners, but a black color is just black under any angles (although the reflection from bright objects has a bluish halo, more than the horizontal, which is why In the light, black areas can lightly light and acquire a "metallic" shade). Black here is so black that the contrast parameter in this case is simply not applicable. With perpendicular view, the uniformity of the white field is excellent. For comparison, we give the pictures on which the SAMSUNG Galaxy K Zoom screens and the second comparison member are displayed the same images, while the brightness of the screens is initially set to about 200 kD / m², and the color balance on the camera is forcibly switched to 6500 K.

Note the excellent uniformity of the brightness and color tone of the white field. And test picture:

The color rendition is clearly not bad, but with all the conventions of the color evaluation in the photo, it is clear that the colors of Galaxy K Zoom is clearly "colder" and have too high saturation. At the same time, the saturation is due precisely an excessive saturation of primary colors, and not software correction. In the proof, we give a test photo with a smooth increase in saturation from the bottom up:

The distinctness of narrow horizontal strips with maximum saturation is good even in the top of the test image, that is, saturation is artificially increasing, but is a side effect of the technology used.

Now at an angle of about 45 degrees to the plane and to the side of the screen. White field:

The brightness at an angle in both screens has decreased noticeably (in order to avoid strong blackout, the shutter speed is doubled in comparison with previous two photos), but in the case of Samsung, the brightness drop is expressed much less. As a result, with formally the same brightness galaxy screen K Zoom visually looks much more bright (in comparison with LCD screens), since the mobile device screen often has to look at a small angle. And test picture:

It can be seen that the colors did not change much of both screens and the brightness at Samsung at an angle is noticeably higher.

Switching the status of the matrix elements is performed almost instantly, but a step (or two) of 16.7 ms width may be present on the front (or less frequent shutdown) (which corresponds to the screen update frequency in 60 Hz). For example, it looks like the dependence of brightness from time when moving from black to a shade of gray 25% (by numerical color value):

In some conditions, the presence of such a step can lead to loops stretching for moving objects, but with usual use to see these artifacts are difficult. Rather, on the contrary - dynamic scenes in films on screens OLED They are distinguished by high definition and even some "dongy" movements.

Constructed by 32 points with an equal interval in the numerical value of the shade of a gray gamma curve did not reveal in neither lights or in the shadows. The approximating power function indicator is 2.40, which is higher than the standard value of 2.2. At the same time, the real gamma curve deviates little from power dependence:

Recall that in the case of OLED screens, the brightness of the image fragments is dynamically changing in accordance with the nature of the displayed image - decreases for light in general images and increases for dark. As a result, the obtained dependence of brightness from the shade (gamma curve) is most likely not a little corresponding to the gamma curve of the static image, since the measurements were carried out at sequential output Shades of gray almost full screen.

Color coverage is very wide:

The spectra component are very well separated:

Note that on screens with a wide color coverage of the color of conventional images optimized for SRGB devices, it looks unnaturally saturated. This can be seen on the above photos. Unfortunately, in this case, the manufacturer "Forgot" (we viewed all the items menu items and pre-installed programs in search of the desired setting) Add a profile selection option with reduced saturation, so the owner of the Galaxy K Zoom when showing photos will have to explain why the faces look carrot and red .

The balance of shades on the gray scale is mediocre, since the color temperature is higher than the standard 6500 K, and the deviation from the absolutely black body (ΔE) from the spectrum is greater than 10, which even for the consumer device is considered an unacceptable indicator. In this case, ΔE is strongly changing from the shade to the shade - this adversely affects the visual assessment of the color balance. (The darkest areas of the gray scale can not be considered, since there the balance of colors does not matter, and the measurement error of the color characteristics on the low brightness is large.)

Let's summarize. The screen has an acceptable maximum brightness and a very effective anti-glare filter, so the device is likely to be able to use outdoor summer sunny day. In complete dark, brightness can be reduced to a comfortable value. It is permissible, and on bright light even you even need to use a mode with an automatic adjustment of brightness that works more or less adequately. The advantages of the screen should include a very good oleophobic coating and common advantages for OLED: true black color, excellent white field uniformity, less than that of the LCD, a drop in the brightness of the image at a look at an angle. To disadvantages - modulation of the brightness of the screen appears during medium and low brightness values, excessive saturation of colors and far from the perfect color balance. It is unlikely that this is the best option for the "photographic" device.

Smartphone

The main characteristics of the device are shown in the comparative table. It is not so easy to highlight a smartphone from K Zoom, similar to any of the current existing, therefore, in the comparative table, first and foremost, cameras, as well as smartphones with something in common with it.

Based on the data of the table, as well as considering the existing prices for smartphones, you can estimate that the price of the smartphone part K Zoom is not more than 15,000 rubles. Yes, competitors in the table are not new, and at the start of sales cost under 30,000 rubles, but we are also interested in more or less real cost, and not the price at the peak of the excitement. We take into account this assessment in further reasoning and conclusions after studying photo-particles.

Interface and Work Features

According to the first sensations in the hands, the coating of the body is pleasant, and definitely better glossy plastic at Samsung Galaxy S4 Zoom. Of course, it would be nice if the coating was more like "plastic skin", like the Galaxy Camera 2 and Note 3, but probably it was necessary to comply with the overall style of the fifth series devices. Therefore, the facial surface of the chamber is made of perforated plastic, like Galaxy S5 (only without coating "Soft-Tach"), which in the people already dubbed the "plaster" or "Zhigulevsky ceiling". We want to stand up on the defense of the manufacturer and note that although the coating is not so cute externally, on the touch it is pleasant and no associations with the plaster does not cause even visual. Apparently, in reality, much looks different than in the pictures.

The smartphone gained a little in the thickness, but it looks more naturally and balanced. It looks like a full-finished device, not an engineering model, as last time: the design of S4 Zoom was, to put it mildly, unsuccessful. The mine of the lens appears from the housing quite a bit. Completeness The image also gives a fully white front panel and completely black rear: S4 zoom frames around the display were white. As it was already possible to notice, the smartphone does not have a tripal nest that it is hardly possible to consider a big loss, as well as the ledge under right hand For a more convenient grip, which did not make much sense. Among other things, by hinting our recommendations to the exclamations of common sense, in Samsung removed the ring of the zonphocator from the lens, which was completely inappropriate on the device of this format. Now only a small button of descent and a volume of volume control that is responsible for the transfocation remained from the physical controls.

You can quickly enable the camera only from the lock screen, which takes about three seconds. You can also start the camera application from the desktop via the appropriate icon or long press the descent button. There are ways to turn on the camera on this. If the smartphone was turned off in the camera mode, then, by itself, when you turn on, it will immediately start the camera application. In this case, combat readiness can be expected four seconds. Ideally, of course, I would like the camera to be launched as quickly as the lock screen appears when the power button is pressed - after a second. Making the amendment to the work of the mechanics that opens the lens, you can add a second. As a result, two seconds are a good result for such a camera. In fact, having learned, you can catch the camera in two seconds, while pre-launching the stopwatch of one of the hands. That is, the result is practically achievable, then everything is resting in the ability of the smartphone - the awakening and inclusion of the lens. Well, here it is quite possible to praise the manufacturer for such substantial refinement.

The interface has undergone many changes - in general, rather positive.

All manual mode settings are now removed up (before they were located on the side of the sensory disks around the descent button), which is very convenient, especially with the fact that it is hardly anyone will use the manual mode in this device, since, due to the discrete exposure values \u200b\u200band In just two diaphragm values, there is practically no meaning in it. Settings for these parameters are duplicated in the settings menu, which also has undergone many changes and has become wider: several parameters are added, both interesting and useless. For example, the remote viewfinder mode is hardly relevant for the camera, which has no tripod nest.

In general, the menu would be nice to divide into two blocks - the necessary parameters and useless rarely used, as items that do not need often Configure, only clutter the menu.

In the modes there was an interesting function " Virtual tour" It allows you to create rollers resembling the promotion of Yandex Panorama. Thus, you can record the route or remove the interior.

Video playback

We tested the capabilities of the video file playback of video files - both when displaying the image to the device screen and using the MHL interface. In the latter case, we used the monitor LG IPS237L Supporting a direct MHL connection using a passive adapter cable from the Micro USB connector on HDMI. Recall that Samsung has implemented its type of interface at the physical level. As a result for connecting external device By MHL, you need to use special adapters or connect standard MHL adapters through simple passive adapters.

In this case, the test was performed using the Samsung branded adapter, while the conclusion on MHL was carried out in a resolution of 1280 per 720 pixels with a frequency of 60 frame / s. With a portrait orientation of a photo-smartphone, the image output to the monitor screen is also carried out in the portrait orientation, while the image on the monitor is written in the screen boundaries in height, and the on the right and on the left are wide black fields.

In this case, the actual permission on the monitor screen, of course, is lower than permission to sAMSUNG screen Galaxy K Zoom. For landscape orientation K zoom Image output to the monitor screen is carried out in the landscape orientation, while the image on the monitor is written in the screen boundary and exactly corresponds to the image on the device itself:

An exception - startout screenwhich is displayed only in portrait orientation. The sound on MHL is displayed (in this case, the sounds were heard through the headphones connected to the monitor, since there are no loudspeakers in the monitor) and it has good quality. At the same time, at least the multimedia sounds through the SAMSUNG Galaxy K Zoom loudspeaker are not displayed, and the volume is adjusted by the buttons on the device body. MHL connection provides battery charging.

Special description deserves video output. To begin with a dialing of test files with a single division for a frame with an arrow and a rectangle (see "Methods for testing reproducing devices and displaying a video signal. Version 1 (for mobile devices)") We checked how the video is displayed on the Samsung Galaxy K screen zoom. Screenshots with shutter speed in 1 C helped to determine the nature of the output of video files with different parameters: resolution 1280 per 720 (720p) and 1920 per 1080 (1080p) pixels and frame rate 24, 25, 30, 50 and 60 frames / s are varied. In this test, we used the MX Player video player in the "hardware" mode. The results of this (block entitled as "SAMSUNG GALAXY K ZOOM") and the next test are reduced to the table:

Note: If in both columns Uniformity and Pass Green estimates are exhibited, it means that, most likely, when viewing the films of artifacts caused by uneven alternation and passage of frames, or will not be seen at all, or their number and notice will not affect the preservation of viewing. Red markers point to possible problemsrelated to playback of relevant files.

By frame output criteria, the quality of video file playback on the device itself is very high, since frames (or frames) can be outlined with uniform intervals and without frames. However, uniform frame alternation is a relatively unstable state, since some external and internal background processes lead to a rare failure of the correct alternation of the intervals between frames. When playing video files with a resolution of 1280 to 720 (720p) on the Samsung Galaxy K Zoom screen, the image of the video file is displayed exactly along the border of the screen, one to one pixels, that is, in the initial resolution (adjusted for some Pentile features). The brightness range displayed on the screen corresponds to the standard range of 16-235 - in the shadows and in the lights displays all gradations of shades. However, dark scenes may not look very good, since the darkest shades are too different in a color tone, which can lead to excessive substitution of compression artifacts.

With the MHL connected monitor when playing a video full-time player, the video file image is displayed only in the landscape orientation, while only the picture of the video file is displayed on the monitor, and only information elements and virtual controls are displayed on the mobile device screen (which disappear after a few seconds before Screen touch only dark pictogram pictogram in the center is displayed.

The results of the output tests on the monitor are shown in the table above in the MHL block. The quality of the output is very good. When playing video files with a resolution of 1280 to 720 (720p) on the monitor screen, the image of the video file is displayed exactly along the screen border with the preservation of true proportions, and the resolution corresponds to the resolution of 720p. The brightness range displayed on the monitor is not equal to the standard range of 16-235, as in the shadows and in the lights a lot of shades are indistinguishable from black and white, respectively. In addition, depending on the selection of the brightness range in the installations of the monitor or the black color of brighter than the true black, or the white dim white dim. As a result, it is reduced both the detailing of dark and bright sections of the image and the contrast.

Typical output - MHL connection can be used for games, viewing photos and movies (with the ability to get a normal saturation of colors), withdrawing web pages and other activities that wins from a multiple zoom of screen size. True, you will have to purchase an adapter for Samsung or find the appropriate adapter, as well as to accept the above-mentioned flank balance specified above.

Image quality

Since K Zoom is a cameraphone, we decided to test it with a camera according to the method for mobile devices. And he showed himself not so bad: the result is generally slightly worse than Camera 2, but it is worth remembering that K Zoom is, rather, a smartphone, and Camera 2 is more likely, a compact camera. Therefore, we will then apply to Camera 2 more stricter than K Zoom, but we will try to be objective. Also, do not forget that, unlike K zoom, smartphones do not have an optical zerofocator, so it may well give a sharper picture.

Standard Test for photosensitivity The camera is not bad.

ISO 100.
ISO 200.
ISO 400.
ISO 800.
ISO 1600.
ISO 3200.

And here it is already beginning very interesting things. In general, K Zoom behaves worse than Camera 2, but at the minimum mean sensitivity values, including ISO 400, copes better.

In manual mode, the camera, like S4 ZOOM, offers only two diaphragm values, so it can be assumed that instead of a diaphragm, one neutral filter is used, which, by the way, it does not work on all focal lengths and does not allow you to "close" a diaphragm. Permissions in the center and the edge of the frame also do not contradict this hypothesis. The quality of optics is low and very reminds Camera lens 2. Permission behavior depending on focus distance Strange, but overall natural: with an increase in the focal length resolution falls. Strange in this case seems to be a certain failure of the edge dependence on medium focal lengths, followed by lifting.

In general, according to absolute values, K Zoom behaves almost the same as Camera 2.

With geometry, everything is not so good. The right edge of the frame has pronounced barrelness, which is observed at all focal lengths. Therefore, fragments are shown from the left edge, which behaves more naturally. At the minimum focal lengths, the left edge demonstrates a small "barrel", which is replaced by the "pillow" on the middle, gradually decreasing to the maximum. You can also note once again that the closed diaphragm slightly worsens sharpness.

On some focal lengths, minor chromatic aberrations can be noticed, which are rather an exception.

Video

An interesting feature of the chamber is the ability to shoot a video of 1920 × 1080 at 60 frames per second. In fact, such a video is visually not very different from 30 frames per second - the picture is also ripple, although it is slightly smaller, but it shows that the smeared is noticeably decreased.

Thanks to the ability to make up to three functions on the sidebar, you can now follow the Multualization mode: The icon displays the acceleration coefficient, which practically eliminates the shooting in incorrect mode by mistake. Previously, sometimes there were a situation when when shooting video, you completely forget that a slowdown is included or, even worse, acceleration. As a result, the video was removed damaged, and it was already impossible to fix it.

The camera lacks photosensitivity during video photography, so with insufficient illumination the picture will be dark.

Outcome

The camera demonstrated only the satisfactory quality of the pictures, but, making the amendment to the wind and discount for relative compactness, it can be concluded that in fact it is not so bad. If you consider K zoom as a result of the work on errors, it can be quite used for five, without a plus.

Despite the low quality of the pictures, the device left basically positive impressions. Yes, the camera often led the soaps of contours or unpleasant blur along the edges, although sometimes there were not bad frames. The problems are most likely a consequence of the design deficiencies of the optical system, because the sharpness in the center was often not so bad. If on the edges of the frame, she at least remained the same, then the camera would be safe could be praised. However, optics do not allow it to do. So, good quality pictures is not about her. On the other hand, from such a camera it is impossible to demand, although it is possible to strive for this. In any case, Samsung is on the right track, and therefore it is quite possible to expect to improve the quality of shooting such a device in its subsequent modifications.

If in the case of S4 zoom wishes about the refinement we had plenty, then in this case you should think. Of course, it would be nice to correct the flaws in the lens so that the sharpness is uniform over the field of the frame. In this case, we would have a really good compact camera with a good quality compact image, and even with a smartphone. If you do focus on the quality of the pictures, you need to still improve the quality of optics, which will undoubtedly entail and increase the cost. And now the price of K Zoom comes up to 26 thousand rubles, and with good optics would have exceeded 30. And if with the price of a little more than 20 thousand rubles for such a device you can still put up, then the cost in the area of \u200b\u200b30 thousand already seems unjustified. Of course, everything rests against the one who tasks is set.

Here we are slightly distracted and traditionally spread about the price. The K ZOOM analogues in the quality of the shooting can be found among the compact chambers worth 3000-5000 rubles, and even cheaper (without deepening in the pricing policy of individual stores). The tenfold zoom has long ceased to be something unusual, and the compact ultraham possessing them is no longer considered. And consequently, the price of such cameras is usually low. Next, remember the smartphone part of the device, which we rated by 15 thousand rubles. Without the causthery, we put these two numbers, and even making a small markup "for the brand", we obtain that the cost of k zoom is clearly below 20,000 rubles. It seems that if you add a good lens here, the cost could be laid within 25,000 rubles, but these are already pure theoreticalation. Meanwhile, the claimed value of universal samsung devices It turns out to be higher than the two components of it separately, which again makes thinking about the feasibility of such a purchase. At the same time, it can still be noted that the autonomy of both devices enclosed in one case suffer. But there is no limit to excellence, and it is quite possible to increase the battery - it would be the desire of the manufacturer.

It is also worth understanding that the camera is a few other plan before us than, for example, Nokia Lumia 1020, where the emphasis was applied to the quality of the pictures. In this case key feature Cameras are not quality picture, but an optical zoom (can't say that without loss of quality). These two concepts clearly share people into two types:

• those who are important to take a picture qualitatively - or not to do at all (Nokia Lumia 1020);
• those who are more important to take a snapshot at least somehow did not do at all (Samsung Galaxy K Zoom).

how ready decisionThis device can be recommended only to those who do not need high quality pictures. It suits you its quality or not - everyone will determine for himself.

And we, in turn, will wait for the next Galaxy Zoom and hope that Samsung will still try to correct the remaining flaws. After all, the beginning is good.

Pixel size Pixels are usually measured in microns. Large pixels are able to capture more light and, therefore, provide better surveillance with low lighting and a wider dynamic range than smaller pixels. On the other hand, smaller pixels allow you to increase the resolution while saving the same sensor size.	1.176 μm (Mikrometters) 0.001176 mm (millimeters)
Crop-factor Crop-factor is the ratio between the size of the full-frame sensor (36 x 24 mm, the equivalent frame of the standard 35 mm film) and the size sensor sizes of the device. The specified number is the ratio of the diagonals of the full-frame sensor (43.3 mm) and the photo sensor of a particular device.	5.64
ISO (photosensitivity) The value of the ISO indicates the sensor sensitivity to the light. Sensors digital cameras Work in a specific ISO range. The higher the number of ISO, the higher the sensor sensitivity to the light.	100 - 3200
Svetlomila Lights (also known as a diaphragm, aperture or F-number) is an indicator of a lens aperture size that determines the amount of light falling onto the sensor. The lower the number F, the greater the diaphragm and the greater the light reaches the sensor. Typically indicates the number F corresponding to the maximum possible aperture of the diaphragm.	f / 3.1 - 6.3
Exposure (shutter speed) Exposure reflects the exposure time. Indicates how long the optics shutter remains open during shooting and, accordingly, the time during which the camera sensor is exposed to light. The longer this time, the more light reaches the sensor. The shutter speed is measured in seconds (for example, 5, 2, 1 second) or in fractions of a second (for example, ½, 1/8, 1/8000). In contrast to DSLR cameras using a mechanical shutter, in mobile devices it is electronic.	16 - 1/2000
Focal length The focal length indicates the distance in millimeters from the sensor to the optical center of the lens. The equivalent focal length (35 mm) is the focal length of the mobile device chamber, equalized to the focal length of the 35mm full-length sensor, in which the same viewing angle will be reached. It is calculated by multiplying the real focal length of the camera of the mobile device to the crop factor of its sensor.

Samsung Well done at least in what to experiment. And experimenting because they have resources for it. Once a completely stunning experiment turned into a new branch of the development of smartphones, because Galaxy Note first Generations surprised everyone much more than today any gadget with a curved display. You can safely say - flew! After some time, the experiments of the head cameras - we got Galaxy Camera on Android OS. And last year we saw the real smartphone, to which the camera was attached -. Despite the fact that the device has not gained great popularity, today we see the heir, who, moreover, opened a new line - K Zoom.

S4 Zoom had obvious disadvantages that, I think, many prevented many choices in favor of this device. Most of all pushed the dimensions: the device was handling for convenient grasp, there was a zoom ring on the lens and even a tripod mount. Add here and not small thickness and mass and use the device on a daily basis it became not comfortable. The novelty has greatly improved in terms of practicality. To begin with, the case material is now not glossy plastic, but exactly the same as in SGS5 - Soft Touch with a characteristic texture.

In addition, the smartphone has become noticeably more compact, especially its thickness. Judging by the numbers, this is not aware of this: the size of the novelty is 137.5 x 70.8 x 16.6 mm, and 125.5 x 63.5 x 15.4 mm in the predecessor. However, in K Zoom removed the handle, the ring for zoom around the lens, and the display rose from 4.3 "to 4.8". So, the device has become much similar to the usual smartphone. However, the mass of 200 grams gives out that something is wrong with the gadget.

Probably the most disadvantage that now there is no fastening for a tripod, in S4 Zoom I even took advantage of several times. But common sense suggests me that people use this fastening much less frequently than a smartphone as a whole, but it would hurt Ergonomics.

Why do you need such a fix? For example, to shoot a Time Lapse video when you need to put a smartphone on a tripod and set up the shooting photo once in some time lapse. As a result, it will turn out something like this:

You can also draw light in the dark. For this, the camera is placed on a tripod, configures on a greater excerpt (more than 1 second), and the person in the frame draws in the frame, for example, a flashlight. As a result, it will turn out something like this:

In fact, if you are interested in photography - it is cool that the smartphone will allow you to do all this, just now you have to come up with how to fix it. And here the help will come different third-party attachments for tripods, there are universal. You can find them on eBay. Therefore, even the refusal of this element, I consider it justified.

Another change is removable back cover. It is really cool! Having removed her for the first time, I immediately understood how one-bone jokes will be in a video border of the smartphone! In general, I first see a smartphone, in the removable part of which there are holes, with a diameter of 55 mm. It is clear, it is assigned to the lens and in the assembled state all this looks very seriously. Under this lid there is a removable battery, a capacity of 2430 mAh, and under it - two slots: for the SIM card and for the Micro SD memory card. The latter is very useful here, since internal memory The device is only 8 GB.

Previously, the battery could also be replaced, but the lid was folded at the bottom of the device. And I liked this option more, because the body was more chtoli, monolithic. In the novelty, the back cover creates a bit, if you put pressure on it.

Of course, in the smartphone remained separate key Camera control, though it became smaller. They are two-position and quite comfortable. Some consider the disadvantage that the camera can not be launched a long pressing on it, I think that this is the opposite cool. The lens will never accidentally leave himself if you accidentally climb the key. Moreover, run the camera from the lock screen - the second thing.

Since the ring around the lens is now missing, the optical zoom is controlled either by the pinch on the screen, which is not very convenient, or the volume keys are approx. By the way, I did not like the ring in S4 Zoom, I did not use it.

In general, the ergonomics worked well. To say that now the smartphone has become a full-fledged smartphone without reservations on a large mass and dimensions, I can not, but now get used to its use much easier.

Camera

And for what is used to get used? Clear case - for photo / videos. Until now, in any other smartphone there is no 10-fold optical zoom, respectively, you can receive such frames that are not available to others. The matrix has increased the number of pixels, now they are not 16 million, and 20.7 million. However, the size of the matrix has not changed - 1/2, "so that the difference is almost impossible to notice the difference. Optical zoom - 10-fold, as before. In general, the quality of photos remained at the same level, but the speed of work has increased, thanks to the new processor. Also, now the video can be recorded in 1080p 60 FPS.

But, even considering practically no modified quality, the photos are still good. In the arsenal, K Zoom has optical stabilization, and xenon flash. With good daily lighting, the photos are obtained very worthy, and strain to obtain a good result only in darker conditions. With insufficient lighting, the matrix begins to noise quite very much.

But in general, in skillful hands to achieve an excellent result is not hard. In addition, there are fully manual mode in the camera app. In the amount, regimes as much as 28, each of them can be removed from the quick access menu to modes, and you can also change their placement. I, for example, placed manual mode immediately after automatic to have quick access to it. In manual mode, you can adjust the excerpt from 1 \\ 2000 to 16 seconds, aperture, exposure and ISO amendment. Unfortunately, I did not find a manual focus. Also cool that in the standard application now has the opportunity to separately focus and separately select the exposure. Earlier it was only in third-party applications.

The focal length of the lens has changed, now the range is from 4.4 to 44 mm, it was from 4.3 to 43 mm.

Examples of photo and video

Display

If the camera received only a cosmetic upgrade, everything else in the smartphone has become better on the head better. For example, display. Earlier by 4.3 "was the resolution of QHD, now we have a whole 4.8" and HD resolution (1280x720 points). And this is 306 dots per inch. Noticeably better than it was before, but the flagship or so much is not in any way. The fact is that the pixel placement scheme in this amoled matrix is \u200b\u200bPen Tile, therefore, each pixel and ladder in fonts, if you look closely, clearly visible. In the rest, as it should be, the problems of the screen is not: bright, contrast, with maximum viewing angles, does not fade in the sun.

Upset the absence of display mode selection item in the display settings. As far as I remember, there is such a menu in all Samsung smartphones with AMOLED displays. In this mode, you can slightly muffle the saturation of colors, because the color coverage in such screens is significantly larger than the standard SRGB, that is, most of the media files will not be displayed quite naturally.

Specifications

The performance of Galaxy K Zoom is provided by the EXYNOS 5260 six-core processor, in which two Cortex-A15 kernels operate at a frequency of 1.7 GHz, and the other 4 Cortex-A7 is 1.3 GHz. Graphics Mali-T624. Random access memory 2 GB, as in most flagship models. Integrated memory - 8 GB, there is a slot for micro SD memory cards. Such iron is enough for everything. You can purchase a flagship model, but, in fact, its superiority in performance can be observed only in benchmarks. For example, the same Real Racing 3 on K Zoom is very smoothly on maximum settings Graphics.

Capacity of the battery - 2430 mAh. It seems not enough, but the body is large, in comparison with other smartphones, it was possible to insert 3,000, as it seems to me. In practice, if you use K Zoom, as a smartphone, he will live on average day. Games take away the charge much faster, and his main task is a photo, make you put a smartphone for charging several times a day. In principle, this is normal, since I always take Pavebank to all sorts of installers, the photography quickly discharges any smartphone.
