Actually, I managed to take some images yesterday, bright sun, outdoors, ISO1600, no NR, EV -2 and featureless, yellow wall and some with a grey roof from beneeth in an angle. I have just checked the images, noisy as expected, underexposed as expected but definitely no banding. Maybe I should have tested with longer exposure times but then it would not have been underexposed. So I guess I am not worried for my camera. I agree with the first sentence in the quote but may not agree with the second. I don't know how to push mine to get banding but I guess if I spend a lot of time I may find a way....Anyway if it's showing in just a few samples then it is more a QC issue and sometimes customer service issue. All current cameras will show banding if you push enough.
Blu, since you are a banding expert :bsmilie: (sorry for the bad joke), did you test your new E-500?
