Lens Overview — Leica 40mm f/2

The Leica Leitz Wetzlar Summicron-C 40mm f/2 is a vintage manual focus rangefinder lens produced during the 1970s, built for the Leica M mount system. Designed around the 35mm film format, this lens represents a piece of classic German optical craftsmanship from the Leitz Wetzlar era, a period widely regarded as foundational to the Leica M system's reputation. The Summicron-C occupies an interesting focal length position at 40mm — sitting between the classic 35mm wide-angle and the traditional 50mm standard perspective, giving photographers a subtly distinctive field of view on 35mm film.

With manual focus operation and a maximum aperture of f/2 as indicated by the Summicron designation, the lens is well suited to the deliberate, hands-on shooting style that rangefinder photography demands. Weighing just 140g, this is an exceptionally compact and lightweight optic that suits the discreet, minimal form factor of the Leica M system. Compatible with 35mm film cameras using the Leica M mount, this lens appeals to collectors, film photography enthusiasts, and rangefinder shooters looking for a historically significant and practically capable vintage optic.
