The question was (in short): After investigating the first images of my recently aquired 50mm distagon, I am wondering whether it is "normal" for this Zeiss lens to show "darker corners" when the aperture is wide open (F/4 and F/5.6). I will try to show some scans of colour material later on this week(end)... to show what I mean.
