Overview

The Leica Summicron-M 35mm f/2 ASPH is a compact, all-metal lens with excellent build and handling, though the clip-on hood of version 1 can be loose. Optically, it is bitingly sharp in the center wide-open but shows significant edge and mid-frame softness. Distortion and vignetting are minimal, and chromatic aberration is rare. Bokeh exhibits a soap-bubble effect that some may find harsh. It suits photographers seeking a high-performing, compact normal lens for Leica M cameras, especially those who prioritize center sharpness and handling over edge-to-edge performance.
