With all the postings regarding this lens and it possibly vignetting. There is one thing to remember. Depending on which camera it is used may make a difference as to whether vignetting is noticed or not. All of the F cameras (F,F2,F3,F4,F5) have a 100% viewfinder while the F90(X)/N90(s), F70/N70 etc. have viewfinders that are only 92% which may account for why some people cannot see any vignetting. I have never had this particular lens in my hands so I have no idea if it vignettes or not. Just my thoughts! Terry
