Samsung Note5, Le Max2, Huawei P9, and Xiaomi 5 are equipped with Sony sensors of different eras respectively. Lemax2 is one of the few IMX230s with optical image stabilization, and Note5 is the ultimate IMX240 (some models are ISOCELL). Xiaomi 5 is this year. The flagship standard IMX298 and Huawei P9 are the only flagship machines that carry the IMX286 for the time being.
Although there is a huge gap in the software training skills of these manufacturers, many people are still very interested in the gap between them.
Inspection items and rulersThe core of mobile phone photography is the camera experience and imaging effects. The main impacts are:
Speed , including focusing speed, shutter response, imaging speed;
The rate of filming, the probability of hand shaking and filming;
Automatic degree , can identify large light difference and low light scene, automatically trigger HDR and night scene mode;
Ease of use , whether the frame has delay/smear/drop frame/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 daylight/light/weak light and extremely low light, whether the white balance (screen color wind direction) and the brightness of the screen can approach the naked eye,
Discrimination can be roughly understood as sharpness. At the same time, the sharpness, detail and naturalness of the picture can be taken into consideration.
The degree of latitude , that is , the ability to show the details of shades at the same time, is basically the same as whether or not the HDR effect is natural and harmonious. After the synthesis, there are problems such as ghosting, white balance deviation, and poor resolution.
The remaining assessments include noise control, color saturation (the closer to the naked eye the better, but Samsung and Huawei will be able to increase some of the recent, in order to please the user's eye), lens quality (including edge deterioration control, anti-glare, atomization Control, wide-angle and pillow-type distortion control, etc.) and many other things.
Although everyone's requirements for the photo experience are almost the same, the proportion of different items for imaging is completely different for different users: for example, the number of Mao who likes to enlarge photo scans will definitely put the power of resolution first. And the proportion is very high; the circle of friends in the sun has a special focus on latitude, white balance, saturation and other items, but the demand for resolution is not high. Therefore, the comparison will be based on different project segments, and everyone will focus on understanding what they care about.
Photo experience
No matter what the small items, Note5's experience has thrown away from the other three domestic machines a distance, so do not explain it independently.
Focusing speed and success rate : Secondly, the Huawei P9 without phase focus is only slightly slower than other machines in the daytime focus, but the focus success ratio under macro and low light is higher than that of the Millet 5 and Lemax2. After Millet 5 and Le Max2, their main problem was the extremely weak light pull-down bellows, and the success rate of focusing fell.
Shutter response & imaging speed & filming rate : Millet's photographing has always been known for its speed, and the filming rate of 5-axis optical image stabilization is also relatively high, followed by Music Max2. Because P9 has no optical image stabilization, it will have forced internal processing and suffer a slight loss in speed.
HDR/Night mode processor speed : P9 HDR and night scene processing speed slightly faster than the millet 5, and the music Max2 processing speed is actually close to the first two, but it will have a viewfinder Caton, it affects the speed experience .
Automaticity : Xiaomi 5 has automatic HDR and night scene trigger function. Huawei P9 has an independent HDR switch, but even if it is not open, it has a certain degree of processing, but the two functions of Le Max are manual, and the performance is not so people satisfaction.
Sample magnification
Comparison of the size of the same scene
The exif information shows that the equivalent focal lengths of Xiaomi 5, Lemax 2, P9, and Note 5 are 28, 26, 26, and 28 mm, respectively. The visual field of Le Max2 and Huawei P9 is larger. Note5's lateral field of view is larger than Xiaomi 5, but it is less vertical.
In addition to the difference in pixel and frame ratio, in fact, the same object, the pixels assigned to Note5 and Le Max2 are higher, followed by Xiaomi 5, and Huawei P9 is a small circle, which is the pixel and wide angle Double disadvantage.
Anti-glare capability (in this scenario, the smaller the light coverage area is, the better) P9 does the best, followed by Xiaomi 5 and Note 5, Le Max2 (or even thousands of Yuan machine).
All machines are in automatic mode and the focus is in the middle. It may be that the fogging on the day of the proof shooting was severe and the humidity was high. Each scene on the machine was shot continuously for five or more scenes. However, four machines had defocus problems in different scenes, and specific proofs were marked.
The sad thing is that even with out of focus, 4 phones directly display coke . Even if Note5 did not calmly face the harsh environment and human error, the S7's dual-pixel focusing is much more important than everyone thinks.

White Balance and Metering: After several system updates, note 5's white balance is clearly adjusted in favor of the eyeballs, the sun will be blue outdoors, and will be reddish under the lights and low light. According to the true reduction, millet 5 and P9 are closer to the naked eye during the day and Max2 tends to yellowish green. In the low light, Le Max and Huawei P9 are relatively close to the naked eye. Xiaomi 5 has been green all the way. There is almost no white balance.
Latitude: The former is jointly determined by the sensor quality and the HDR algorithm. Note5 refrains from other mobile phones by virtue of the algorithm; Huawei's P9 performance is also good; Xiaomi 5 has its own performance due to its HDR algorithm; the Max2 is obviously latitude. The problem of darkness in the dark details is obvious.
Noise control: In daytime and normal light scenes, Huawei P9 has obvious traces of algorithm smearing, and adjusts the contrast, noise control even better than Note5. Millet 5 noise is only slightly worse than Note5, while Le Max2 is still pulled down a distance. However, after the deterioration of light, millet 5 in order to maintain the power of resolution, noise growth is very rapid, very weak light is basically made of grain noise the entire picture, Le Max is full of noise, the screen is clean, but the details are lost.
Discrimination: In addition to music Max2, 3 machines have sharp traces, especially Huawei P9, the edge of the line appears "algorithmic edge." However, in terms of power of analysis, P9 dropped during the day and in the lighting scene. It was only possible to exceed the excessive Max2 in extremely low light. Millet 5, Le Max2's day and night resolution and Note5 can each have a victory or defeat; after the light is degraded, only the analysis of millet 5 can follow Note5 all the way, but really only the power of analysis, and music Max2 as long as the light is weaker Will enter the crazy smudge mode, the resolution and the speed of decline is comparable to the mobile phone without optical image stabilization; and Huawei P9 in the extremely weak light with large pixels and dual camera algorithm optimization, analysis and power and millet 5 have to win each other.
In addition to the noticeably stronger Note5 and the significantly weaker Music Max2, Xiaomi 5 and Huawei P9 are the machines with different directions. Xiaomi 5 wins the overall power of analysis. Huawei P9 is far less powerful than many media outlets, but extremely weak light is discriminated against. The power and overall noise control is really good, but the overall power of analysis is really a big short board...
