I have been using a 21mm Elmarit for a couple of years and I never have had a problem. All my transparencies and prints have had no colour fringing or vignetting. It is much better than my previous Super Angulon which was stolen from me by a fast talking flatlander from Pacific Beach. BTW, my Elmarit is the pre-Aspheric version with no coding. It is a much superior lens than the C-V 21mm that I had been using in the interim.
