which setting for vignetting? This just gets weirder and weirder

Few people suggested I do a full camera reset and see if that would help. I was pretty sure it would not, because why would it, I got a brand new camera so surely it was at factory settings. Turns out it did help.

The obvious green rings are gone. I can still see a bit of posterization, which is eerily similar to what I would get with careless noise reduction. But maybe this is just so deep in the shadows that I'm at the limits of tonal range here.

I tried changing one by one all the settings I originally changed in hopes I would identify one that was causing problems. Nothing. I fiddled with everything that came to my mind. I tried different shooting modes including high res, silent, different drive modes, different ISOs etc. No anomalies.

How's that for a head scratcher?

My guess it's a compensation of the lens vignetting that's causes this weird rings.

There was a very similar problem with some Samsung camera bodies.

That's the trouble! It's the only setting that effects raw files and it is known to cause problems with long exposures.

Is there a setting for  vignetting control?
