As for who is the strongest in China, ZUK Z2 Pro、 One plus three, Huawei P9 and Xiaomi 5 all have their own followers, but there is no doubt that the best domestic photography will be born among them. Now let the sample sheet be the final word:
Hardware parameters
The photo contest of flagship machine has already become the internal battle of Sony sensors. Last year, one plus two OV sensors were "mixed in", while this year, the "mixed in" was the ZUK Z2 Pro of ISOCELL (of course, part of Samsung series are ISOCELL). These two aliens Commonality of It's all large pixels+optical anti shake, which can't help but make thousands of computer users daydream about its night performance.
Investigation items and scales
The core of mobile phone photographing is the photographing experience and imaging effect. The main factors that affect the experience are:
speed And also includes focusing speed, shutter response and imaging speed;
Film rate , the probability of destroying the film by shaking hands;
Degree of automation , whether it can identify the scene with large light difference and weak light, and automatically trigger HDR and night view mode;
Ease of use , whether the viewfinder box has problems such as delay/shadow dragging/frame dropping/noise full screen, but the priority is not as high as the first three.
The imaging effects mainly include:
White balance and photometry In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Discriminative power Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
Tolerance , that is, the ability to show details in the light and dark at the same time. For mobile phones, this is basically equivalent to whether the HDR effect is natural and harmonious, whether there are ghosts, white balance deviation, and poor discrimination after synthesis;
The remaining assessment contents include noise control, color saturation (the closer to the naked eye, the better, but Samsung and Huawei will be able to raise it recently to please users), lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow deformation control, etc.), and many other contents.
Although everyone's requirements for photographic experience are almost the same, for different users, the proportion of different imaging projects is completely different: for example, the number of Maoists who like to enlarge photos and scan will definitely put discrimination first, and the proportion is very high; The party in the circle of friends attaches great importance to tolerance, white balance, saturation and other items, but the requirement of discrimination is not high. Therefore, the comparison will be divided according to different items, and it will be better for everyone to focus on understanding what they care about.
Photo experience
Focusing speed&success rate: The speed and focusing success rate of the ZUK Z2 Pro are relatively high. Before the last version was updated, there was a problem that manual metering was easy to overexpose. After the update, a lot of corrections were made; The Huawei P9 has no phase focusing, and the limiting focusing speed is slightly slower, but it is better than the stable focusing speed and success rate after the light becomes worse; The focusing speed of Xiaomi 5 and One Plus 3 is good, but the possibility of defocusing under extremely weak light is slightly higher than that of the other two machines.
Shutter response&imaging speed&film rate: The shutter response and imaging speed of the four machines in the default mode are very fast. However, in terms of film completion rate, Huawei P9, which does not have optical anti shake, declined significantly after the light became worse, and users had to work hard to stabilize the machine for night shooting.
HDR/night view mode processing speed : One plus three HQ mode (multi frame composite optimization imaging without increasing the number of pixels) and HDR mode are both put in the background for processing, and there is almost no waiting time. After taking 8 or 9 consecutive pictures, you will be prompted that they are being processed. Now, HDR experience is the closest to Samsung Apple's machine; The processing speed of P9 and Xiaomi 5 is in line with the standard; The processing speed of the Z2 Pro is close to that of the normal flagship, but the HDR mode will make the foreground appear stuck for nearly half a second. The user experience is not very good.
Degree of automation : Xiaomi 5 has automatic HDR and automatic night view, but the HDR algorithm has been a slot for many years, and its availability is not high; The P9 night view mode of Huawei will be automatically triggered, with an independent HDR switch. However, by default, the samples will have slight HDR processing, and they are all user managed; Both One Plus 3 and ZUK Z2 Pro have automatic HDR without night view mode. In the latter case, it is just a prototype in the night view, but the one plus three HQ mode is an enhanced mode that can be used day and night, which is very worthy of being turned on frequently. However, it cannot be turned on at the same time as the automatic HDR mode, which is a pity.
View: Usually we don't mention the photos of the flagship aircraft, because the difference is really small. However, ZUK Z2 Pro has a low tolerance of photographing and shooting, and the dark parts are easy to become black. In addition, the machine's light measurement is darker, so the experience is not good.
Wide angle and lens quality
Xiaomi 5 and one plus three are common 28mm equivalent focal lengths (exif information display of one plus three is estimated to be different from that of normal machines); Huawei P9 displays 27mm; The focal length of ZUK Z2 Pro is 4.22mm, but the sensor size is unknown, so the equivalent focal length cannot be calculated.
The size difference of the 12, 13, and 16 million pixel proofs is slightly smaller than we thought, but the wide angle/field of view of several machines is larger: the field of view of P9 and ZUK Z2 Pro is close, which is a bit larger than Xiaomi 5 and One Plus 3.
The same vase is proportionally enlarged. P9 is one circle smaller, ZUK Z2 Pro is one circle larger, and Xiaomi 5 and one plus 3 are one circle larger than ZUK. It is easy to predict that P9 will be weaker than ZUK Z2 Pro in discrimination, and they will be weaker than one plus three and Xiaomi five.
In terms of anti glare ability (in this scene, the smaller the light source cover range, the better), they are all good. Except Xiaomi 5, which is slightly worse, the performance of other machines is very close. There will be some ghosts and floodlights in front of the strong light source of the four machines, but they are light and easy to avoid.

Range of panoramic mode and contrast of picture distortion (The longer the scene, the smaller the compression distortion)
The one plus three panorama proof is highly available, with accurate light measurement and white balance, harmonious light and shade connection, and the discrimination of Wang Zheng remains, but the stitching trace is relatively more obvious.
The photography algorithm is still Xiaomi's weakness. Although the panoramic mode of Xiaomi 5 is relatively natural in view angle range, light metering and stitching trace processing, the white balance and pixels are too low and the availability is low;
Huawei P9 is slightly better. In addition to dark metering, others are acceptable;
The performance of the ZUK Z2 Pro is not flattering. The pixel number and stitching trace are handled well, but the light and dark connection of the metering is too poor, and the shooting angle is relatively ordinary.
Daytime proof sheet
All machines are in automatic mode, the focus is in the middle, and there is detailed exif information marked in the weak light proof. Each machine in each scene will take more than 5 samples and select the best one as a representative.

metering
Huawei P9 is slightly darker in overall light measurement, but slightly higher than that seen by the naked eye in extremely weak light;
The ZUK Z2 Pro is special. Its outdoor strong light metering is darker, but it is slightly higher indoors and in weak light;
The whole photometry of Xiaomi 5 is close to the naked eye;
One plus three days and light metering is normal, and slightly dark in weak light, similar to iPhone.
white balance
The accuracy and stability of the white balance of one plus three is slightly better. Even in weak light, the white balance is closer to the naked eye. The overall yellow green color is slightly higher, but the amplitude is very slight;
The second is ZUK Z2 Pro and Huawei P9. The background color of the former tends to be slightly red, and it tends to be blue-green under extremely weak light, and the hair color tends to be real; P9 is slightly yellow and warm;
and The white balance of Xiaomi 5 is very obvious. It is OK in the daytime, but as long as the light gets dark, it is obvious and uniform red, which is far from the accurate white balance
Tolerance&Saturation&Contrast
Huawei P9's all-weather mandatory HDR makes it seem more tolerant;
The tolerance of one plus three and millet five is essentially the same as that of the sensor, but the one plus three with better HDR algorithm is more natural;
The ZUK Z2 Pro with the largest unit pixel size should have the highest tolerance, but the actual performance is not satisfactory, and the saturation drop under high sensitivity is more obvious than other machines.
In terms of saturation and contrast, Only P9 has obvious traces of adjusting the gamma curve and contrast, the light difference of the picture will be higher than that seen by the naked eye, and the picture will be more transparent, but the dark part will be easier to black. In addition to smearing, the noise reduction algorithm of one plus three also has the trace of increasing saturation, which makes it more colorful in weak light.
Noise control
The noise reduction algorithm and strength of ZUK Z2 Pro are similar to that of Le Max2. The image is always clean, but many details are lost, which will give people the illusion of not focusing well under weak light;
At the other end is Xiaomi 5, which tries its best to ensure details. Its noise control is much better than that of a few months ago, but even though it is more detailed, it is still the most obvious among several domestic flagship;
Huawei's P9 and one plus three strategies are much more "neutral", but the noise processing of one plus three is much finer, and there will be noise reduction when the light is good (see smearing in the sky), and the details remain excellent.
Huawei P9's noise control is worse than one plus three, but it is one of the best ones in China.
Discriminative power
In addition to the extremely weak light, Huawei P9 can win against the strong daubed ZUK Z2 Pro, and its analytical power lags far behind in the whole process. This is probably the so-called powerlessness;
Although the pixel of ZUK Z2 Pro is only a little higher than that of Huawei P9, its ultimate analytical power is unexpectedly good, and it does not lose one plus three too much;
One plus three, maybe because There is algorithm noise reduction in the whole process, which is lost For some sharpness and details, the ultimate analytical power is less than that of Xiaomi by 5, but the range is very small.
After the light becomes worse:
Under the light and ordinary weak light, it is almost one plus three. Under the noise smearing and sharpening, a lot of details are retained. The discrimination is smaller than Xiaomi 5 all the way, and the picture is very clean.
Xiaomi 5 is followed by Huawei P9. The light and ordinary weak light have always suffered from poor pixels, but the extremely weak light is strong.
The big pixel+optical anti shake ZUK Z2 Pro should be the strongest night shot, but it is a pity that the algorithm is mediocre and has a tail.
