Anonymous, 22 Jan 2023Thank you for the information. I have to check the "se... moreYup, those are raw calculations for perfect conditions. Unfortunately, another factor is the material used to produce lenses, coating, etc. Also, when designing a lens, you need to set some priorities, like better average performance on whole coverage, or a bit sharper center of the image but softer edges. And another thing, these numbers will be different for different colors, as those have different wavelengths. So when looking at the numbers keep in mind, that those are theoretical maximum values, not possible to obtain in real life. Anyways, you can clearly see, that having such big resolutions in smartphones, gives nothing. Long story short, yes, 200 Mpix will give you a better image quality than 12Mpix, but not even close, to the difference in resolution.

I have to check the "set circle of confusion based on pixels" checkbox for the camera to become diffraction limited. Based on this calculator, the maximum resolution for a 2/3" sensor and an aperture f/2 before the camera becomes diffraction limited is 51 MP. For a 1" sensor and an aperture f/1.8, the maximum resolution before the camera becomes diffraction limited is 131 MP.

Enter the number of pixels (200), the expected sensor size (It's type 1/1.3 so sits somewhere between type 2/3 and 1) and the F stop (F1.8). You will be told that the lens is diffraction limited.
From what I have seen, the lens on the 64MP camera on S21/S21+ does a great job resolving all the details, but the contrast is slightly low at the pixel level. 108MP shot from S21 Ultra, on the other hand, looks significantly hazier in comparison, suggesting the limit of the optical quality in this form factor.

"Like s22u had one of the best low light camera period"
That largely comes down to the processing rather than the lens' ability to resolve 108MP worth of details (In low light many phones force disable the full resolution mode and fall back to the binning mode, so you will be looking at a 12MP image no matter what you do).

As always ... moreI haven't seen a single phone with a 108MP sensor that can resolve more details than those with 50/48MP sensors on this site, and I can say that because I checked every single one of them so far. There, you have my confirmation.

Anonymous, 21 Jan 2023I asked because you said "if." So is it confirmed... moreIt is. Depends on the exact size of the "hole", so the actual lens size (as f stop is the focal length/diameter of the effective aperture of the lens. ). You can find some clever calculators online, the given sensor size/lens size will give you an answer if the sensor resolution is higher than the maximum resolution of the light image that comes through the lens. But keep in mind, that those calculations are done without taking into account losses on the material of the lenses themselves. It just tells you the bare maximum. Also, that number is slightly different for different light wave lengths, so different colors.

I would much prefer to see actually great implementation of bigger sensor with something like 16-18Mpix. Level of details would be enough, there would be less to process for the processor, so the process of making HDR/postprocessing could be quicker or more advanced in same time.

There is a calculator, that tells you exactly this: even in the perfect situation, with no glass in the lens, the resolution of the light itself in such a small opening is much lower than the resolution of the sensor. Adding diffraction of the light on the lens just tells, that 200 Mpix is just marketing. You cannot go against the laws of physics.

Anonymous, 20 Jan 2023So it's your hypothesis?No, it's the fact. If the lens isn't capable of resolving 200MP of details, then the sensor that sits behind it also cannot capture 200MP of details. Not only that, having 16 pixels of the same colour grouped together means the sensor will struggle to interpolate the values across pixels of the different colours since they are so far away from each other, resulting in significantly worse artifacts.
Just compare a 50MP shot from Mate X2 and a 200MP shot from Edge 30 Ultra from the balcony scene, you can see that the latter is not resolving any finer details than the former, while showing a lot of moire at the same time.
