After the recent wave of new engines, Note5、iPhone 6s Plus、LG V10、Nexus 6P、Mate8、Lumia950， It will become the PK object of the new flagship as the old flagship and benchmark. In the field of photography that cannot be quantified digitally, the difference between the strengths and weaknesses of these benchmarks has formed a relatively appropriate Photo level scale But where is the gap between these benchmarks? This is the main purpose of our comparison:
The focus of this comparison is The three most important items of mobile phone photography: photography experience, white balance and discrimination . According to different photographic needs, The proportion of these three blocks will vary from person to person. The saturation, contrast, metering, etc., which also affect the first impression, are generally small differences between flagship machines, so they will be interspersed in the sample analysis.

Camera parameter comparison
The highest pixel is Lumia950, but because of redundancy design, 20 million pixels can only output 18.69 million pixels of samples at most, and the advantages of 16 million pixel models are not as obvious as expected.
There are many contradictory items in the photos:
The focal length/wide-angle also affects the discrimination. The smaller the focal length is, the larger the wide-angle is, the more difficult the discrimination is, and the deformation of the scene at the edge of the picture（ Wide-angle distortion ）The more serious it is, the worse the edge image quality is generally; Here, the iPhone's 29mm focal length sacrifices the field of vision for discrimination, while Mate8 does the opposite;
The larger the unit pixel size, the better the weak light performance, but at the cost of the total number of pixels decreased; Among the six machines, the most extreme representative is the Nexus 6P. The largest sensor size only puts the smallest number of pixels;
The larger the aperture, the more light input, the better the weak light performance and illusion effect, but the edge degradation will be more obvious, and a good lens can greatly reduce this problem; The iPhone has stuck to the f2.2 aperture for many years, which is one of the important reasons why its weak light is surpassed;
Optical anti shake has algebraic and axis number differences, which can improve weak light performance and film rate. However, more complex lens structures will have problems of edge degradation and decline in ultimate discrimination.
Photo experience
The automatic mode of six machines can automatically trigger HDR and night view without manual adjustment. Except for the obvious white balance fluctuation in the HDR/night view mode of the Nexus 6P, the white balance of the HDR/night view mode of other machines is relatively reliable;
Focus: ranked Note5, iPhone 6s Plus, Nexus 6P, Lumia950 Mate8、V10。 The difference between the first five machines is not obvious. Only the LG V10 (IMX234) that does not support phase focusing has a big gap. The V10 can focus with a laser near by, but when the shooting distance exceeds 5m, the focusing speed will be slower than other machines, and the phenomenon of weak light pulling down the bellows is also more obvious than other machines;
Shutter response&imaging speed: Note5, Mate8, iPhone 6s Plus, Nexus 6P, Lumia950 V10。 The price of the V10 frenzy algorithm is that the shutter always gives a feeling of one card for one card. HDR and night scene processing also take a long time, and the photo taking experience is obviously behind other machines. However, Lumia950 and Mate8 are at the bottom in terms of film rate.

White balance and metering: The performance of Note5 and Lumia950 is excellent, and even the white balance of Mate8 is closer to the naked eye than the yellowish green iPhone; The Nexus 6P and LG V10 have similar white balance and photometry, both of which are red and dark. V10 is more serious. In addition, V10 and Mate8 have low contrast. and In large color difference scenes such as red flowers and green leaves, Lumia950 and Nexus's 6Ps have very obvious color deviation.
Discrimination (click the picture to view the large picture): The strongest ones are Note5 and Lumia950. The former relies on a more powerful sharpening algorithm, while the latter relies on the number of pixels to enrich the picture details; Then there are V10, 6P and iPhone 6s Plus, while Mate8 is not in the same horizontal line at all.

White balance and metering: Each company has a lot of room for improvement. Except for the Lumia950 and Nexus 6P, which are always flying in the white balance, we can not discuss too much about them. In fact, other models are only half the weight, and each has a certain probability of white balance drift. In addition, the iPhone 6s Plus and Mate8 will suffer from insufficient exposure in weak light.
Discriminative power（ Click the picture to view the large picture): Indoor and under strong light, each machine can shoot at a lower ISO, ranking the same as in the daytime: Note5 and Lumia950, V10, 6P and iPhone 6s Plus, Mate8。
Weak light and extremely weak light: the noise reduction and sharpening algorithm of Note5 is against the sky, and the details are exaggerated; Although V10 has been surpassed, it is also quite strong; Although the Nexus 6P is white balanced, its color saturation is much higher than that of other models, and its analytical power is well preserved, followed by Lumia950 and iPhone 6s Plus.
