Re: This just gets weirder and weirder

The limit of tonal gradation is what came to mind. I've seen it in every camera since my 420  when I shoot super dark blue skies, posterized rings. Perhabs a 12 bit thing, I don't know. The sharp edges you showed also reminded me of the faulty GR vignetting correction that they later fixed.
