Because of the change of Samsung's product positioning, the Galaxy Note20 Ultra, which was supposed to be Samsung's strongest mobile phone of the year, has now become a mobile phone whose positioning and price are lower than the Galaxy S20 Ultra. However, even if the main camera CMOS is consistent, Samsung will use better lens modules or algorithms on the Note series every year. So this year we are also waiting for Note20 Ultra with great expectations, waiting for it to regain the glory of Samsung's ancestors in cameras.
parameter
Take a look at the hardware as usual:
Ultra wide angle: Samsung Note20 Ultra maintains S20 Ultra's ultra wide angle hardware. The latter has always been the strongest super wide angle of DxOMark before Xiaomi 10 Ultra came out. The Xiaomi 10 Ultra's 128 degree ultra wide-angle view is also one of the best in mobile phone history, but the sensor is still the 20 million pixel, 1 μ m IMX350. In theory, the best ultra wide angle hardware should be the IMX586 with one plus 8 Pro. This photo contrast, by the way to see which is actually the best super wide angle.
Main camera: Samsung Note20 Ultra is still a 108 million pixel S5KHM1, but its usage is different from that of Xiaomi 10 Pro's S5KHMX with the same pixel. Samsung has a 9 in 1 output of 1200W pixels, which is used as a 1200W pixel sensor with 2.4 μ m unit pixels. Xiaomi 10/10 Pro is 4 in 1, which is used for 2500W pixels (1.8 μ m).
Long focus: Samsung Note20 Ultra is the reduced telephoto version of S20 Ultra, from IMX586 telephoto to 1 μ m old friend S5K3M5+"5X mirror". According to exif information, the actual zoom should be about 4.9 times (long focus 123mm, main focus 25mm), and the camera starts to switch to long focus at 4.8 times. Xiaomi 10 Ultra inherits the legacy of S20U. With the IM586 and 4.8 times optical lens, the focal length is longer than S20U, but the aperture is correspondingly reduced to F4.1.

[Super Wide Angle Summary]
One plus 8 Pro: The wide angle is obviously smaller, and the basic discrimination is naturally advantageous. In addition, the IM5864800W mode is still on, so we can't play together. In addition, the noise control and extremely weak light performance of Plus 8 Pro are stronger. But the shock of ultra wide angle imaging is not as good as the other two.
Note20 Ultra: exif shows the equivalent focal length of 13mm (12mm for millet), which is also true · super wide angle. Its CMOS 1.4 μ m is not small, and its tolerance is even better than that of One Plus 8 Pro (advantage of multi frame synthesis algorithm?). The picture is sharp and has high contrast, but the noise and discrimination are weak.
Xiaomi 10 Ultra: Like the main camera, after the super wide angle HDR multi frame synthesis, the focus value of exif will also change, and the actual angle of view will be slightly trimmed (13 mm after cutting, but the actual angle of view is still one circle larger than Samsung Note20 Ultra (also 13 mm). Xiaomi's exif fans. In terms of vision, Xiaomi 10 Ultra is impeccable and shocking. But after all, it is a small bottom of 1 μ m, and the tolerance and smearing performance of the light scene are average, so the extremely weak light scene can not be played at all.
In terms of ultra wide angle strength, I will rank first in the list of one plus 8 Pro. Samsung Note20 Ultra and Xiaomi 10 Ultra are 50 to 50, depending on personal preferences. The former has weak light and strong focus, while the latter has a large field of vision.
5x zoom contrast
The parameters of the telephoto are too different, in fact, there is no direct comparison value. Here is mainly to let you feel the difference of sensors, which can be summarized as "IMX586 is good".
Samsung Note20 Ultra is actually 4.8-4.9 times optical focal length, one plus 8 Pro is 2.2 times optical focal length (the camera interface only provides a shortcut button of 3 times zoom), and Xiaomi 10 Ultra is 4.8 times optical focal length.

2x zoom contrast
2x zoom, light scene 1
One plus 8 Pro does not have a convenient 2x zoom button. Here we use a 3x zoom (call a 2.2x optical variable lens, 1.0 μ m). Xiaomi and Samsung both use a 2x zoom, but Xiaomi triggers a 1.4 μ m subphoto with a 2x focal length. Samsung uses a main camera digital cropping (possibly a hybrid zoom?).

Samsung may not trigger the hybrid zoom when zooming twice. The result strictly follows the magnification of the optical zoom. One plus 8 Pro here uses a 2.2 times wide zoom lens, which will naturally win. But I didn't expect Samsung's 108 million pixel main camera would have such a weak digital zoom in the light scene.
[Summary of Long Focus]
Xiaomi 10 Ultra: Even if the aperture is small and the light becomes poor, the IMX586 can still easily press the S5K3M5 on the ground to rub. If we say that the bottom level is killing people, then the bottom level is killing people. However, Samsung is better at white balance and multi camera consistency.
Note20 Ultra： From the first day we knew S5K3M5, it is a very common, highly sensitive and very weak 1 μ m CMOS. Put it behind a small aperture telephoto lens. Even in the evening when the light is not too weak, it has to be pushed higher. The image tolerance and details are naturally not good. Fortunately, Samsung's noise reduction algorithm is good, and this telephoto head can also be triggered when the light is weak, saving some practicality and face.
In front of the absolute hardware advantage, everyone learned how to write the word "cry". Although Samsung's algorithm accumulation is stronger, the Note20 Ultra has no connection with cameras in other focus segments between the main camera and 5x zoom (actually 4.8x switching). Even if there is a hybrid zoom, the commonly used 2-3 times focal length is difficult to play with the ordinary optical zoom lens. Don't talk about playing Xiaomi 10 Ultra. It's enough to play every game.
Interestingly, Samsung is honest. No matter how many times the digital zoom is, exif information only records the focal length information of the camera itself, while domestic manufacturers modify the output focal length information according to the zoom magnification. Although Samsung's approach is not convenient for later viewing of digital zoom magnification, it is more prudent than some manufacturers who deliberately confuse "optical zoom, hybrid zoom and digital zoom".

The night view mode effect of Samsung Note20 Ultra is very obvious. The brightness of the image climbs from "slightly higher than what the naked eye can see" to the level of "night vision device". The details of the image are more abundant, and the ultimate discrimination is not weakened too much, so the usability is very high.

Even if the night view mode is not turned on, the Xiaomi 10 Ultra is already at the night vision level, but the algorithm is unstable (the problem of noise explosion in the pavilion scene can be triggered repeatedly because of the mystery). When the night view mode is turned on, the dark details explode strongly.

The super night view of Samsung Note20 Ultra has greatly improved, but the basic performance of CMOS is far from good. The night vision mode will still lose to Xiaomi 10 Ultra, and the fans will cry again.
【 Summary 】
One plus 8 Pro: The performance is balanced and the white balance is stable. The rollover rate of multi frame synthesis is very low, and almost every picture will trigger (only the highlight suppression is not the best one). The effect of dual ISO in the scene with very large optical aberration is indeed better than that of conventional CMOS such as Samsung Note20 Ultra.
Note20 Ultra： The white balance (base color) tends to be more magenta. It may be the pressure brought by 100 million pixels, which affects both the imaging speed and the film rate, but it is at least the same level of photography experience as one plus 8 Pro, which is better than Xiaomi 10 Ultra when triggering multi frame synthesis. Note20 Ultra is strong in Samsung's multi frame synthesis algorithm, with stable performance and high trigger rate. But the sensor is really weaker than the other two, and the details and extremely weak light performance suffer.
Xiaomi 10 Ultra: The OV sensor is really proud. It is the first time to see that OV can suppress the CMOS of Sony and Samsung. Although Xiaomi's white balance accuracy and stability have made great progress this time, Xiaomi's algorithm has not been stable. After updating the firmware, the HDR and multi frame synthesis trigger of the main camera are not active. Although this saved the photographing experience, in many light scenes, Xiaomi was straight out, which led to the highlight suppression being occasionally thrown away. However, as long as HDR is triggered, the effect will be instant, peerless and strong enough to beat the street (if Xiaomi sees this, please pay for it). In addition, how do you know which samples of Xiaomi have super night view? Compared with other samples in the same scene, the view angle of the picture should be smaller. In addition, in its exif information, the equivalent focal length will become smaller (fill in exif hammer # manual funny. jpg).
As a matter of fact, the main camera of the three top flagship platforms does not differ much in their analytical power. After all, they are all 12 million pixels, and the output unit pixel is more than 2.24 μ m, so there will be no big difference at night. In terms of white balance, these sets are very good, mainly because of the preference for hair color.
In this era, the gap between flagship photography and low light scenes is mainly the tolerance of high light ratio and low light scenes. Better than OV48C, it can also capture dark color differences that cannot be seen by the naked eye in extremely low light scenes. This ability is invincible for the time being.
To sum up, although Samsung relies on the multi frame synthesis algorithm, the main camera can compete with Xiaomi 10 Ultra, one plus 8 Pro (even if it loses, it has not been abandoned too much). Super wide angle is not the first, but it is also very strong. The most unfortunate thing is the telephoto part. Five times of the telephoto is common, and there is no relay of two or three times of the telephoto. The 2-5 times of the telephoto section is in a bad situation.
What else can I say? Star powder will cry next year.
