The selling points of Xiaomi 11 are 2K screen, Snapdragon 888 and 3999 yuan. The camera of Xiaomi 11 is not changed much compared with Xiaomi 10. It is still a Samsung S5KHMX sensor with 100 million pixels, but it has extended the focal length and narrowed the aperture, and also introduced a 2 times long focal length macro lens.
Although Xiaomi 10 matches Xiaomi 11, Xiaomi 11 Pro corresponds to Xiaomi 10 Pro/Xiaomi 10 Ultra. But as a machine guy, I am either a stick or just curious. I want to see what changes have taken in the photos of Xiaomi 11 compared with Xiaomi 10 Pro/Xiaomi 10 Ultra.
Specifications
First recite the camera parameters of Xiaomi 11:
Front 2000W, S5K3T2, 0.8 μ m, 1/3.4 '', F2.2 (front aperture is F2.3);
Main camera: 10800W, S5KHMX, 0.8 μ m (4 in 1 to 1.6 μ m), 1/1.33 ", OIS, F1.85, 6.83mm, equivalent 25mm, 7P lens (lengthened focal length, reduced aperture);
123 degree ultra wide angle 1300W, OV13B10，1.12μm，1/3.06''，F2.4；
Long focal length 500W, S5K5E9, 1.12 µ m, 1/5 ", F2.4, 49mm (the long focal length on Redmi K30 Pro).
Xiaomi 10 Pro should be one gear higher. Although the main camera is S5KHMX, the equivalent focal length is 25mm and the aperture is F1.69; Ultra wide angle is 117 degrees IMX350 (2000W, 1 μ m, 1/2.78, F2.2 aperture), with 3.7 times light variable 800W telephoto (OV08A10, 1 µ m, 1/4.4 '', OIS, F2.0), and 1200W double telephoto (S5K2L7, 1.4 µ m, 1/2.6 ", dual core focusing, F2.0);
The Xiaomi 10 Ultra camera is no longer in one dimension: the main camera OV48C (4800W, 1.2 μ m (4in1 into 2.4 μ m), 1/1.32 ", F1.85, 8P lens+OIS), the ultra wide angle is 128 degrees IMX350 (2000W, 1.0 µ m, 1/2.78", 7P, F2.2), the five times telephoto IMX586 (4800W, 0.8 μ m (4in1 into 1.6 µ m) 1/2 ", split OIS, F4.1), and the 1200W double telephoto (S5K2L7, 1.4 µ m, 1/2.6 ", dual core focusing, F2.0).

Here are some important camera contents in the Xiaomi 11 evaluation:
Although they are Samsung HMX, Xiaomi 11 has 27.14 million pixels output (6016 * 4512), while Xiaomi 10 series has 25.16 million pixels output (5792 * 4344);
So even if Xiaomi 11 has a longer focal length (F1.85, equivalent to 25mm), the field of vision is still very close to Xiaomi 10 series (F1.69, equivalent to 24mm);
The Xiaomi 11 camera is more prominent, but the edge coma control of near object imaging is far better than that of Xiaomi 10 Pro (after all, it is still super bottom, and there are still barrel distortion and coma degradation in near object imaging)
Ultra wide angle contrast
In this part, we don't talk about martial arts morality. Let's have fun. After all, the super wide angle of Xiaomi 11 is directly inherited from that of Xiaomi 10, which is 1.12 μ m 1300W at 123 degrees. How can it compete with the super wide angle of Xiaomi 10 Pro and 2000W IMX350 of Xiaomi 10 Ultra (their wide angle is set at two extremes, the former is small, and the latter is "fried chicken" large).
Comparison of ultra wide angle sample size and vision of three mobile phones
The Xiaomi 11 field of vision is sandwiched between Xiaomi 10 Pro and Xiaomi 10 Ultra, and 123 degrees is compared with the standard ultra wide angle setting. But with 1300W pixels, the proof is two circles smaller than that of the big man with 2000W pixels.

The ultra wide angle performance of Xiaomi 11 is normal, and the field of vision is sufficient, but the discrimination is limited by the number of pixels. It is slightly inferior to Xiaomi 10 Ultra, which is ultra super wide angle, and the gap between Xiaomi 10 Pro, which is "small field of vision" and high pixels, is even more obvious. The super wide angle of Xiaomi 11 is different from that of the first line, mainly because there is a gap between HDR enthusiasm and tolerance.

Although they are all 100 million pixels, Xiaomi 11 has not been cut. The 6016 * 4512 sample is very huge, and the straight sample size is between 8M-16M.

The most abundant picture information is actually Xiaomi 10 Pro. However, Xiaomi 10 Ultra is sharp and fierce with high contrast, which will give the illusion of better discrimination.

Xiaomi 10 Pro and Xiaomi 10 Ultra have some false colors at the edge of highlights, and the lens quality of Xiaomi 11 seems to be better (after all, the aperture is small and the focal length is long)

100 megapixel vs. night view
In the latest version of firmware, the "108MP mode" and "108MP mode of professional mode" of Xiaomi 10 Pro and Xiaomi 11 have very little difference in discrimination between the two modes except for the difference in white balance. On Xiaomi 10 Ultra, it is more difficult to distinguish, even the difference in white balance is small.

The metering of Xiaomi 11 in 108MP mode is significantly higher than that of the other two mobile phones, so the dark details will be more dominant. The picture details are better than Xiaomi 10 Ultra, and the noise reduction is OK, but the edge of the object is not as sharp as Xiaomi 10 Pro, obviously the algorithm has not been adjusted properly.

The MIUI 12.0.9 firmware of Xiaomi 11 is not yet mature in night view mode, weak light focusing is not stable, and the film rate is not high. The night scene mode is faithful to reality, and it will not be exposed suddenly, but mainly improves the dark details.

After the aperture is reduced, it really has a negative impact on the weak light performance. Although the shutter of Xiaomi 11 is generally slower than that of Xiaomi 10 Pro (1/10 second vs. 1/13 second), it also has a better multi frame synthesis effect. Both noise reduction and highlight suppression are significantly better than that of Xiaomi 10 Pro, but there is a certain gap in the image detail discrimination.
Summary
The performance of Xiaomi 11 basically met expectations, mainly due to the improvement of coma control, image noise reduction and highlight suppression. The former is a new lens module with longer focal length, smaller aperture and more prominent. It is not clear whether the improvement of noise reduction and highlight suppression is due to the new ISP of Snapdragon 888. As the price of aperture reduction, the weak light performance of Xiaomi 11 has declined.
It may be a firmware pot. The current metering of Xiaomi 11 is not stable, and it is more likely that it will be slightly brighter. In addition, the edge of the object in 108MP mode is slightly blurred. Focusing logic and performance also need to be improved. In a brief summary, we mainly shot "five five opening" with Xiaomi 10 Pro, even lost a little, and waited for OTA improvement (updated on January 5: the camera related OTA really came soon).
