Renee, I have had that lens for almost ten years and it has always made me very happy. Tiny and light. The only complaint is with the Copal who got a sticky opening ring, but nothing to do wit h the lens itself. It is a sharp lens on LF lenses standards, and contrasty. But dont expect any LF lens with per haps the exception of the "Digitars" series to match the sharpness of your Mamiya!
