    Overview

    The Leitz Canada Summicron-R 90mm f/2 is a well-built, all-metal lens with smooth focus and ergonomic ring placement. Optically, it is very sharp wide-open on film, but on digital M9, corners are softer at larger apertures; f/5.6 is optimal. It is heavy and front-heavy, with a long focus throw that slows handling. It suits film shooters seeking a classic 90mm f/2, but digital users may prefer sharper alternatives.
