I tested a number of lenses for this problem, all my Zuikos, some Nikkors
and some independents. The worst offenders were a Tamron 90/2.5 and a Nikon
50mm/1.8 (E series). I did manage to duplicate the problem on film but the
effect is very much reduced and would probably go unnoticed in anything but
a controlled test.
If you're not satisfied with the Z 100/2 I'll gladly take it off your hands
!
