It’s not always harmful when it’s there https://www.photopills.com/calculators/diffraction

But diffraction is a very real concern and should be a part of the discussion. If a design has pixels that are so small that diffraction will affect the image when used with a typical lens and typical aperture then this cannot be ignored because users will need to allow for this or accept that in practical terms with most commonly available lenses/apertures the camera isn’t going to deliver what they might think it will. Most of these cameras are designed to use broadly similar lenses and broadly similar apertures, so diffraction limitations must be a consideration rather than something to be ignored because it will have a measurable as well as predictable effect on the MTF and LP/PH. What would be the point of having a camera that claims to resolve 12K yet has pixels too small to actually achieve this with any commonly available lens? Would it not be beneficial to understand what a sensor will actually deliver in a real world example with a real world lens? Most of the cameras tested will take a PL lens, whether directly or via an adapter and even if the same lens can’t always be used, using a similar lens at the same aperture and the the Imatest slant test will give an appreciation of what will be the reality of using the camera in a typical configuration will be rather than leaving people to believe that more pixels must always equal a greater resolving power.

Couldn’t agree more.

Thanks for the link, I think that settles the debate :)

That’s BS

How can 14 bits beat ARRIs 18 ? : )

Not sure why the 12 bit limit in R3 and R1 for cinematography, sensors can handle 14 bits in 40fps. I’m deducing buffer route is because uncompressed 14 bit 6K RAW can’t go directly onto media and RAM can handle it.
Perhaps the reason for 12 bit limit lies in processing or heat or media minimum sustained write speed limitations.

Suggestion – compare R1 DR in 12 bit Cinema RAW and 14 bit stills.

It should outperform A9III DR and sensitivity…

Okay here you go and read if this makes sense putting on a camera sensor on micro scales or they can just use larger pixels and higher A/D bit depths.
