Google's Nexus pro son series has always been photograph Not very good. This year, the Nexus 5X and 6P used Sony's latest IMX377 sensor, which has a unit pixel size of up to 1.55 μ m, and the night shot performance is quite expected. Apart from Huawei's Nexus 6P, LG's Nexus5X probably represents the highest level of Prince series photography. But can it beat the legendary LG G4?
explain
Hong Kong colleagues have obtained these two machines and made photo comparison. Although some test scenes and focus are not scientific, affecting the sample confidence, the imaging characteristics of the two machines can be basically compared.
Parameters of two cameras:
Nexus5X adopts Sony IMX377 sensor, with 12.3 million pixels, 1/2.3 inch, unit pixel size of 1.55 μ m, f/2.0 aperture;
LG G4 is a Sony IMX234 sensor, 16 million pixels, 1/2.6 inch, 1.12 μ m unit pixel size, f/1.8 aperture.
forecast
It is worth noting that they are all produced by LG. The camera tuning of G4 must have been done by LG, while the camera tuning of Google's own son is rumored to have been completed by OEM and Qualcomm. It can be inferred that the 5X produced by LG should have better photo performance than the 6P produced by Huawei. The 5X is likely to be the Nexus equipment with the strongest photo performance.
In the daytime, 5X should have the strong sharpening habit of LG, but if the pixel difference is there, it will almost certainly lose to G4;
In weak light, although the IMX377 has a pixel size of 1.55 μ m, it is not much larger than the iPhone 6's 1.5 μ m, and its light sensitivity and noise control are not much better than the iPhone 6's. From the fact that the iPhone 6 was beaten by this generation of optical anti shake models, it can be inferred that the 5X may still be at a disadvantage in the face of optical anti shake models;
In ultra weak light, optical anti shake will not have much practical significance. In addition, 5X may have LG's night scene smudging algorithm bonus, but it may have unexpected performance.
Wide angle/contrast/metering/white balance
Wide angle: The size of Nexus5X is 4:3, and that of G4 is 16:9. In addition to the wide angle difference, their field of vision varies greatly. The Nexus 5X is much larger vertically, while the G4 is only slightly larger horizontally. At the same distance, the 5X image can hold a lot of scenery.
Contrast: G4 picture is not as transparent as 5X, and the color is not as bright as 5X (lower saturation). In contrast/metering/saturation that affect the transparency, each item of G4 is input a bit, resulting in the final transparency of the sample not as good as 5X.
Metering: G4 is habitually brighter than Nexus 5X. The metering of Nexus 5X is slightly darker, and the difference between the two sides is superimposed. As a result, the contrast of G4 is reduced. The high tolerance brought by the 5X outsole sensor allows better retention of light and dark details of the image, and also increases the gap in transparency/contrast.
White balance: The difference between the two is not big, and both are relatively stable during the day, except that the 5X color temperature has a slight tendency of blue and cold.

Scene 2, central zoom in
Scene 3, zoom in at the center (look at the font edge, 5X sharpening is heavier than G4)

G4 is a machine that stands at the peak of the mobile phone's analytical power. Its sharpness is still unmatched by its gross strength, and it can even slightly beat the Nokia 1020 (of course, although its analytical power is high, the richness of picture details is still lost to the 1020). 5X lost its power of discrimination unexpectedly and obviously, but its performance was also very good, better than the domestic model of 16/20 million pixels, and its tolerance (Scene 4) was even higher.
Weak light
Because the performance of the samples will be greatly improved after HDR+is turned on, the Nexus 5X samples below will all be shot in HDR+mode, and G4 will still be in automatic mode.
Scenario 5

Scenario 6. 5X turns on HDR+and becomes furious. The light box and the dark details of the building behind it are all in
Zoom in at the lower right corner of Scene 6. However, G4 is more discriminating, and it also has several positions.

Extremely weak light
Scenario 7
Scene 7, zoom in at the top. In extremely weak light, the optical anti shake has become weak, and the two machines are racing ISO. In this scene, G4 has not yet triggered the automatic night view mode. At this time, the advantage of 5X big bottom sensor comes out. Noise control and discrimination are better than G4.
Scenario 8
Scene 8, zoom in at the bottom left
Scene 8, zoom in on the left
The light here is extremely weak. G4 has triggered the night scene mode and started LG's violent smearing algorithm. The purity of G4's image is amazing, and noise can hardly be seen, but the color saturation and contrast decrease significantly. 5X has a lot of red and green noise, but the picture details are still rich, the color saturation is very high, and the performance is amazing.
summary
One sentence conclusion: Nexus5X is strong in color saturation and tolerance, while G4 is strong in discrimination and noise control.
Daytime: Although Nexus5X still has a large gap in discrimination, its color saturation, image transparency and appearance are better than G4. The image tolerance brought by the big bottom is amazing, and many scenes with large light difference can also "bring HDR effect";
Weak light: although there is an old saying that "the bottom is bigger than the bottom", the G4 still has the legendary model of optical anti shake and LG night view algorithm. In most scenarios, the G4 can perform better, but its tolerance still loses a bit;
Extremely weak light: Although G4 is still stronger in discrimination and noise control, its color saturation drops significantly, and the appearance of the proof is not as good as 5X, and the gap is huge. The biggest regret is that Nexus5X does not seem to inherit LG's furious night scene smudging algorithm
