This is a crop from a shot taken at a very high iso 26000 @ f5.6 125.  I see pinkish banding. Is this acceptable/normal at such a high iso?

are we talking about the same banding?

white dots  (by me) showing banding, and this looks to me as  a uneven calibrated read out point (channels)

Hi Mikael,

Thanks for helping all the way from Sweden!!!

Yes this magenta striping or banding has been called "pattern noise" and is what I am referring to. If it is "uneven calibrated read"  then is it very serious, what can be done to fix, will it continue?
