I need help! I just bought this lens used and it seems to work fine on my Nikon D70s. I was attracted to this lens as it could be used on 35mm bodies, and when I tested it on a F100 at the store, it looked fine through the viewfinder. But when I got home and tried it on my F90 and F401x bodies there is significant vignetting! Is this problem because of my older film bodies? Any help would be great!
I haven't used it enough to comment further!
