Overview

The Leitz Wetzlar Summicron 35 mm f/2 (I) is a compact, all-metal lens with excellent build and handling, though some copies may have a wobbly aperture ring or loose hood. Optically, it delivers sharp center performance wide-open but suffers from edge softness and some purple fringing in high-contrast scenes; bokeh can be harsh with a 'soap-bubble' effect. It is ideal for Leica M users seeking a lightweight, classic rendering, but those wanting modern sharpness may prefer the ASPH version.
