Small flagship final stick | Sony XZ1 comprehensive evaluation

Although Sony released the XZ1 and XZ1 Compact phones at the IFA conference in 2017, we did not see the BNI version of the Sony XZ1 until October 31. The Sony XZ1 is equipped with the Snapdragon 835 mobile platform With 4GB RAM + 64GB ROM, with 5.2-inch screen, 1080P traditional ratio of screen support SonyTriangle Phantom and cover the fifth generation of Corning gorilla glass, support IP65 / 68 standard dust and water level, the factory pre-installed Android 8.0 system The battery capacity of 2700 mAh, supports Qualcomm QC 3.0 technology.

Still camera Sony's housekeeping skills - it uses a 19-megapixel rear lens, 1 / 2.3-inch CMOS and supports five-axis anti-shake technology.Its built-in sensor with three stacked structure, a separate cache layer Shooting up to 960fps super slow motion video front camera 13 million pixels, equivalent to 22mm wide-angle also supports five-axis anti-shake. Previously we saw on the XZP IMX also decentralized to the small screen flagship XZ1 body.

Appearance: Sony has always adhered to the aesthetic

Speaking of the appearance of the Sony mobile phone, is actually a controversial, delusional topic.On the one hand, Sony mobile phones, as always, with a delicate appearance, excellent feel and excellent industrial design capabilities, but the appearance of a five-year follow-up is indeed Some fatigue.

Front 2.5D arc glass with a very high integration of the metal body, so that the whole convergence is perfect, smooth from front to back, the integration level is very high. The top of the fuselage is, as always, the front camera, handset I speaker , The sensor is distributed, the underside of the handset is familiar SONY logo, of course, the width is always the same.

Button arrangement, the arrangement of the Sony XZ1 is still not much change - the thin runway round power button supports fingerprinting power button above the volume keys and a half-ring antenna strip, the bottom right is Sony's balanced design from the beginning of the existence of the camera button has a sense of ceremony, but also half-focus function.

The left side of the fuselage only card slot and the top of the top two antenna strips, because the back and side frame is all-metal design, so the antenna with such a design, can be called on the phone beautiful and functional and have both clever Design. Card slot is the same as the conventional card-free design, direct plug can be. Sony XZ1 uses three selected two card slot design, at the same time in order to ensure the phone waterproof / dustproof, when you pull out the card slot Automatic shutdown to protect the phone to some extent.

The back of the fuselage is extremely simple, only the central body of the metal etching Xperia logo.At the same time in order to ensure the normal operation of the NFC function, the top of the fuselage has a deliberately expelled antenna, but also to avoid the whole body behind the metal shield.

Sony exclusive IMX400 rear camera is located in the upper left of the fuselage, with the same XZP has a certain degree of bulge, it seems IMX400 powerful performance, but occupy the volume is quite large.

Overall, the appearance of the Sony XZ1 is still top, both the appearance of the phone feel or are both very good on the integration.But after all, the overall design has been used for too long, it will inevitably make people tired of beauty, Moreover, the full screen The era of the Tao, even if the upper and lower borders for dual speakers to consider, but this 'Happy Valley' border is also somewhat outdated.

System: 8.0 conceal the lack of 'localization' pain

Although the Sony XZ1 is the earliest batch of 'Oreo' phone, but you may not look out from the system UI design it with Andrews 7.1 What is the difference between the overall style or icon design The previous generation is almost the same.

However, in actual use, we can still feel the uniqueness of the Android 8.0. Whether it is installing applications more permissions management and restrictions or the application of the background optimization and limitations have demonstrated that Google is progressing to strengthen the relatively chaotic Android Determination of camp governance.

On the other hand, the more powerful native split-screen PIP function and the newly added PinnedShortcuts (which can be compared to 3Dtouch) further enhance Android's ease of use.

Sony XZ1 as the first non-Google mobile phone to use Android 8.0 naturally have reason - Sony itself is the founder of the native Android.Although Android belongs to Google, but Andrews open source project AOSP participants also include Android camp Of the other vendors, of which Sony contributed a lot to AOSP Sony contributed a lot of code to AOSP, for example, in the latest Android Android O, Sony contributed more than 30 features including LDAC features for the new system repair 250 bugs, which are expressly mentioned in Google's new feature on Android O.

Sony's ROM, of course, has its own unique advantages as the closest native ROM: first, it is easier for ROMs to experience the latest features of Android due to the fact that Sony devices are generally included in 'Open Devices'. For example, Sony in 2013 Year release of the Xperia Z1, there is still an official Android 7.1.1 kernel code support.On the other hand, close to open source system However, the Sony XZ1 has a huge third-party ROM support Moreover, the official also provides equipment to unlock support.

Of course, all the advantages can not be summed up in addition to the lack of localization of Sony system, not enough 'ground gas' shortcomings of the state-line version of the system will still be pre-installed with Baidu and other related procedures, but you can delete itself. Actions and "energy-saving" two main functions, in addition to change is not much.

In general Sony's system is completely fluency enough, but away from 'easy to use', especially in the mainland market, 'easy to use' is still a long way to go, comes with Sony Featured Application can be seen.

Screen: Who says the top screen must use 18: 9

Compared to the previous generation XZs, the most appealing feature of the Sony XZ1 on the screen may be the new HDR technology, which originally followed a 50-year-old brightness range standard, SDR, to a maximum (10 third power) brightness information on the display device can not reflect the true human eye to see the situation (10 of the fifth power.) Using the HDR instead of SDR standard, the screen can take full advantage of the television performance, display HDR Multi-level video content brightness and rich colors, greatly improving the display.

In terms of parameters, Sony equipped with a 5.2-inch LCD screen, 1080P resolution in smaller sizes, whether pixel density or brightness are satisfactory, not to mention the HDR brings the display to enhance Below we pass the BM-7A actual test.

In short, the Sony XZ1 1920 × 1080 resolution HDR display excellent brightness, color, viewing angle and contrast, etc., but stick to the 16: 9 aspect ratio of the screen and a very small screen design Let Sony XZ1's screen is not so perfect, slightly regrettable.

Take pictures: data quality of the camera

The essence of the photo is inseparable from several dimensions, such as resolving power, color orientation, white balance, tolerance and so on. Therefore, our evaluation standard starts the standard photographing environment and sets up a dataized photographing template. At the same time, Imatest software quantifies the experimental data and finally obtains Truly credible evaluation results.

1, resolution

Resolution refers to the ability to distinguish the details of the original photographed, the better the resolution is, the better control of the details, the more natural the transition of the detail of the picture, There are many ways to test the resolution, here we choose linear test mode, it The advantage is very intuitive, with the naked eye can be observed, we intercept part of the test sample position as a test area, test Sony XZ1 camera resolution.

2, white balance

White balance is an indicator of the whiteness of a mixture of three primary colors, red, green and blue, and many people experience the problem of using a digital video camera: images taken in a fluorescent room Green, the scene photographed in the indoor tungsten light will be yellow, while in the shade of the sun to take some pictures are somehow blue, the reason is that the 'white balance' on.

3, the color deviation from the value

The 24 Color Check test card in the studio environment was taken and analyzed by Imatest to get the color deviation ΔE and the white HSV saturation Color difference ΔE is actually the difference between the measured color and the true color.

4, dynamic range

In photography, the dynamic range refers to the brightness range of the subject - the brightness span of the darkest point to the brightest point in the subject, and the shading color card in the studio environment, which is calculated by Imatest to analyze the camera's dynamic range.

Sample: Exclusive IMX400 black technology full

From the specifications point of view, the Sony XZ1 IMX400 CMOS theoretical pixel value of 21.2 million (the actual output pixel value of 19 million), the highest shooting 5520 * 3840 resolution image. CMOS diagonal length of 7.73mm, size 1 / 2.3 Inch, a single pixel area of ​​1.22μm Support for 1/120 seconds to read 1930 megapixel images and shoot up to 960fps ultra-slow video, the structure of the traditional Bayer array.

From the above parameters, the Sony IMX400 main force point on the high-speed processing and video capture above, from the static image parameters, the 21.2-megapixel figure in Sony's own Exmor RS CMOS also belongs to the more advanced bit Times, 1 / 2.3 inch CMOS area of ​​the same front-ranked, can provide a relatively good picture quality output unit pixel 1.22μm less than some of their 1.44μm products, and HTC's UltraPixel 2μm compared to there is not a small gap Bayer array Is a traditional RGBG structure, which is different from the RGBW structure of IMX298 and IMX398. Therefore, in view of the integrated light input, it may eat some losses.

But this time Sony made a breakthrough in the CMOS architecture level adjustment IMX400 pixel layer and circuit layer in the new DRAM layer (dynamic random access unit), this part of the entire CMOS module which acts as a cache role, Used to store the image information obtained by the pixel layer, thus greatly improving the speed of the sensor data processing.According to Sony's data, the new CMOS can read 1930 megapixel images within 1/120 seconds, the speed of its own flagship CMOS IMX318 4 times faster.

Back to the Sony XZ1 body, its camera interface basically followed the Sony mobile phone has always been the style, and our commonly used Android phones are quite different, including object tracking, predictive shooting, AR augmented reality, creative effects, including Sony feature filming system in the Sony XZ1 complete coverage.

Here are two major functions of the Sony XZ1: five-axis anti-shake and anti-distortion. 5-axis anti-shake is not the first Sony XZ1 is a function of the transplant from Sony micro-single. In fact, its own equipped with the anti-shock features SteadyShot (Electronic Image Stabilization) itself is already good. The five-axis image stabilization includes Yaw & Pitch, Roll, and XY axes for image stabilization in both standard and full HD (30FPS) video shots Very good.
