Re: What's this??!! ( circular ring artifacts )

The same can also be seen in Samsung cameras and apparently also Ricoh.

With Samsung cameras you can't turn it off. Changing the lens correction settings does not remove the banding, but it goes away if you use manual lenses.

Maybe this is some minor "offset correction" (applied to the RAW) to cope with corner issues caused by the small flange focal distance and which only becomes visible ("amplified") when pushing shadows.

For some reason Sony have deactivated this "correction" (or whatever it is) when you disable lens vignetting correction altogether, which is actually a good thing.
