Xiaomi was sprayed "in the wrong direction" after reaching 100 million pixels last year. This year, in addition to the IMX700 used by Huawei, it has also produced three "low pixel" bottoms CMOS, namely, "IMX689, Samsung S5KGN1, and Howell OV48C", representing the latest level of three CMOS suppliers in this line. They are equipped with One Plus 8 Pro (and Find X2 Pro), vivo X50 Pro+(and iQOO 5 series), and Xiaomi 10 Super Commemorative Edition.
The first step of this photo comparison is to see the actual performance of next-generation large pixel CMOS. Secondly, "incidentally" compare the sub camera systems of Xiaomi 10 Premium, Xiaomi 10 Pro, One Plus 8 Pro, and vivo X50 Pro+. The focus of this part is how different the IMX586 used in ultra wide angle and ultra long focus will be from the conventional scheme.
The essence of "evaluation" is comparison in the final analysis, whether it is the comparison between the screen, performance, endurance, charging test and the benchmark data/target plate, or the direct comparison between different machines. It is always the most direct and simple to let the proofs speak by themselves. We try to make simple comments, mainly providing basic notes for everyone.
PS：
Camera parameters
Let's review the CMOS parameters briefly:
One plus 8 Pro is an optical anti shake IMX689 (dual native ISO, full pixel omnidirectional focusing, 12bit sampling), 4800W, 1/1.43 ", 1.12 µ m per pixel, 2.24 μ m per 4in, F1.78, 7P lens; In addition to Huawei Mate30 and P40 series, its ultra wide angle is the most active parameter, IMX5864800W pixels, 120 degrees wide angle; The telephoto is weak, and the S5K3M5 superimposition digital cutting is about 2.2 times light variable, and it is 3 times mixed zoom;
Vivo X50 Pro+is an optical anti shake Samsung S5KGN1 (full pixel dual core focusing), 5000W, 1/1.31 '', unit pixel 1.2 μ m, 4in 1 into 2.4 μ m, F1.85； There are 2 times and 5 times of telephoto, 5 times of telephoto is relatively strong, and ultra wide angle parameters are general;
Xiaomi 10 Pro is an optical anti shake Samsung S5KHMX, 108 million pixels, 1/1.33 ", 0.8 μ m (4 in 1 into 1.6 μ m), F1.69。 Although it is said that the direction is wrong, the big bottom is equipped with F1.69 aperture (the quality of the lens is not up to standard, and the poor control of the smart difference causes the edge of the near object shooting to be easily blurred). If it is completely completed, it is still very strong. The double focal length is also strong, giving 1.4 μ m+F2.0 aperture. The ultra long focus is not periscope type, the actual optical zoom is about 3.7 times, and the parameters are ordinary. Ultra wide angle has the advantage of high pixels, but the angle of view is small;
Xiaomi 10 Premium is an optical anti shake OV48C (dual native ISO, 12bit video, full link HDR10), 4800W, 1/1.32 ", 1.2 μ m (4 in 1 into 2.4 μ m), F1.85, 8P lens. The previously strong 2x telephoto has been completely retained, and the ultra wide angle of view has increased to 128 degrees, equivalent to 12mm (15mm for Xiaomi 10 Pro and 14mm for iPhone 11 Pro Max). The ultra long focal length is also very strong. Like the Samsung Galaxy S20 Ultra, it has the IMX586, and it is 4.8 times the actual light variable value (but the aperture is reduced to F4.1).
Ultra wide angle contrast

Ultra wide angle, daytime scene, central amplification (during the shooting of the sample, the light has changed, and it is impossible to compare the white balance and metering)
One plus 8 Pro ultra wide angle 4800W mode, compared with other machines
In the default mode, Xiaomi 10 Pro is more powerful in super wide angle discrimination, and one plus 8 Pro is more tolerant. But as soon as the 4800W mode of 8 Pro is opened (the sample even has some sharpening), it will be reversed. For the ultra wide angle with the highest analytical urgency, the 4800W mode can be normally opened, although the photo volume will soar to more than 10M
Comparison of the lower right corner of ultra wide angle sample sheet
The ultra wide-angle camera with one plus 8 Pro has a large bottom and good lens, and the edge image quality is better than Xiaomi 10 Pro, Xiaomi 10 Premium and X50 Pro+.
The perspective of ultra wide angle lens is compared, and the wide angle field of vision of Xiaomi 10 Premium is significantly larger
Ultra wide angle lens, size comparison of the same object
Xiaomi 10 Pro is high in pixels (2000W), and the same object can be divided into more pixels, which has a natural advantage in discrimination. Because of the wide angle, the pixel advantage of the Xiaomi 10 Premium Edition is spread evenly into the field of vision advantage.

After the light becomes worse, the pixel advantage of Xiaomi 10 Pro will be weakened, and even surpassed by the Xiaomi 10 Super Commemorative Edition with a larger wide-angle (this is metaphysics, and the algorithm of the new machine will be improved?). The X50 Pro+'s ultra wide angle performance throughout the whole process is excellent and normal.
The super wide angle of Xiaomi 10 Super Commemorative Edition is exaggerated in the perspective, and the dark light performance has also been improved to a certain extent, and the lens quality is OK. On the one plus 8 Pro side, although the default mode is only 1200W pixels, the whole process has the advantages of image brightness and noise control brought by the big bottom. It's just that 1200W pixels are too low, and the 4800W mode cannot open a wide gap.
Comparison between long focus and ultra long focus
Comparison of 2x telephoto lens (one plus 8 Pro is about 2.2 times), scene 1
The one plus 8 Pro with larger optical magnification will naturally take advantage of the 2-to-3x zoom, followed by two millets with 1.4 μ m bottom, and the S5KGD1SM with X50 Pro+is the weakest (although there is 1.6 mm unit pixel size after 4in1, there is only 800 W pixels left).
Ultra long focal head contrast, scene 2, 5 times zoom (one plus 8 Pro does not have the lens of this focal section, actually it is a 2.2 times long focal length digital cutting)
The zoom contrast of Xiaomi 10 Pro is 2x, 5x, 10x and 50x. This story once again tells us that digital cutting beyond the scope of optical zoom is useless.
5 x, 5 x zoom, 48 megapixel mode, 10 x and 120 x zoom contrast of Xiaomi 10 Premium
According to exif information, the limit zoom of Xiaomi 10 Premium is 122.56 times (3064mm/25mm). It seems that the equivalent focal length of the main camera should be slightly greater than 25mm. At this stage, the biggest problem of Xiaomi 10 Ultra telephoto is that it is difficult to focus on a distant target when shooting at 120 times telephoto, and it needs an iron hand or a tripod.
The super long focus discrimination of Xiaomi 10 Premium is significantly improved compared with that of Xiaomi 10 Pro. In this scene, for the first time, a "telescope" can clearly see the supporting rod of the iron tower. As for how to choose:
The 48 megapixel mode has a very light processing trace, but it retains a lot of picture details, and the field of vision should also be greater than 10 times zoom. Jilao recommends using the 48 megapixel mode with 5 times zoom;
If it is used by ordinary people, it is better to use 10 times zoom at most. If it goes up, it will waste the picture field of vision and "increase power consumption". It is better to work hard to stare at the target with an iron hand than to cut by yourself after 10 times zoom.

Summary of long focal length
For the telephoto side, most mobile phones now use 48 million, or even 64 million pixels. They can achieve the effect of 2x zoom through the main camera digital cutting, which is enough to replace the ordinary 2x telephoto lens. Therefore, the telephoto head in this era has to have more than twice the optical variable lens, telephoto imaging beyond the main camera, or, like Xiaomi 10 Pro, it is used to fill the defect of "too serious brightness difference in near object shooting".
It is more suitable for taking portraits and near objects with a 2x telephoto. Two Xiaomi are more powerful (the same hardware, different tuning, Xiaomi 10 Pro is more powerful than sharpening). The S5K2L7, a 1.4 μ m pixel sensor, can still play today. With the addition of 8 Pro, the actual performance of the telephoto is OK because it has 2.2 times the magnification. However, the X50 Pro+'s 2 times zoom head is a bit soy sauce. After all, the 5000W output of the main camera can also achieve similar results.
For ultra long focus lenses, it is better to say that they "only increase power consumption", and it is better to say that they increase the possibility. Domestic manufacturers have embarked on the arms race of zoom in an all-round way. It is expected that there will be high magnification continuous zoom models next year, but the starting magnification is generally more than 5 times, which will also take up more body space (the dual speakers of the Xiaomi 10 Premium version are squeezed into asymmetry because of the super long focal power).
From the actual effect, the super telephoto of Xiaomi 10 Premium is really strong, and only Huawei PPP (P40 Pro+) can compete with it. The next echelon is the Vivo X50 Pro+'s true 5x light change, and then the Xiaomi 10 Pro with the actual 3.7x light change. The results are basically directly related to the optical magnification, and the difference between different algorithms is still difficult to make up for the gap between optical zoom.

Main summary
In terms of subjective discrimination, Xiaomi 10 Pro won without suspense. No matter which mode is more suitable for "counting hair", but in front of several large pixel models, the weak light scene will be overtaken. The others are 1200W-1250W pixel models, which are not obvious. The main reason is that the sharpening and contrast of One Plus 8 Pro are both increased, and the "at first glance" proof is clearer, but the details of the picture are not natural and a bit "dry".
In terms of white balance, the Xiaomi 10 Premium is the most accurate one in most cases. In some scenes, Yijia and Vivo tend to turn green and red, while the Xiaomi 10 Pro is really floating. In terms of light measurement, Xiaomi 10 Premium will have significantly higher picture brightness in low light scenes, brighter and richer dark details, and extremely low light scenes are more likely to become night vision devices. In most cases, the metering of vivo is the one closest to the actual situation.
summary
Xiaomi 10 Premium, One Plus 8 Pro and X50 Pro+are all very close to the main camera performance (after all, the specification gap is not big). With more powerful algorithm processing, the appearance is pleasing, but a bit unnatural. And they are all the bottoms that are fearless of darkness, and the extremely weak light also has good details. Xiaomi offered the best white balance in history on the top version of Xiaomi 10, but the focus is really strong. While the Xiaomi 10 Pro is "in the wrong direction", as long as it is not in extremely low light scenes, its discrimination is obviously one gear higher than that of the mainstream flagship (but it is also one of the flagship models with the most serious poor close range vision and blurry highlight edges).
Instead of letting several machines open the distance, it is their "sub camera group". At the same time, it also proves to us once again that IMX586 (the ultra wide angle of Yijia, the super telephoto of 10 meters) and S5K2L7 (two sets of 2 times telephoto of 10 meters) are good CMOS.
On the ultra wide angle side, 1200W pixels are spread out into the ultra wide angle, and the details are not enough to see. As a result, the IMX586 ultra wide angle of one plus 8 Pro can not open a big gap in most scenes. However, after the weak light scene or the 4800W mode is manually turned on, it is still easy to hang other products. While the high pixel large wide-angle scheme of Xiaomi 10 Premium is less discriminative than that of Xiaomi 10 Pro, it has been found that such details and weak light performance can be achieved in wide-angle.
Long focus, as mentioned above. Two Xiaomi's 2x telephoto (S5K2L7) both performed well. However, if there is no dual core focusing 1.4 μ m level CMOS, or if the light change value is more than 2 times, the 2 times long focus can be avoided (after all, the main camera digital cutting can also have close details).
On the ultra telephoto side, the IMX586 also brings very obvious advantages to the Xiaomi 10 Premium. Although the aperture is very small, it can also be triggered when the light is weak. It can easily win the X50 Pro+'s true 5 times light change all day long. Except the super long focus of Huawei P40 Pro+, other models can't play at all.
