If so, what has the response been? I can't imagine that vignetting is a sample to sample problem. If it was, it would seem to indicate that the position of lens elements in various lenses is radically different. That would surely show up as other problems such as lack of sharpness. These lenses are made to very fine tolerances, I doubt this is a "problem" which can be corrected - it's a result of the lens design. Vignetting in a given lens depends on: - filters and hoods in use (nikon filters and hood should be ok) - focal length - focus distance - aperture - image cropping in the viewfinder and prints - film contrast (high contrast film may show vignetting more) - your own sensitivity to vignetting The reason vignetting is "hit and miss" is that sometimes these factors come together and cause vignetting, sometimes they don't. For a lens of this type, I would be very surprised if there wasn't some vignetting. Roland. == Roland Vink ============================ [EMAIL PROTECTED] http://home.ait.ac.nz/staff/rvink/
