Leica Summicron-M 50mm f/2 Reviews

None better

By Alan
Rated 5 out of 5
Date: 2026-07-24

With the Leica 28 and 35mm Summicron lenses in my kit, I just had to have it. I still love my Voightlander 50mm f/1.0, and several other Voightlander M-mount lenses, but there is nothing like the build of a Leica, like my M11-P. Autofocus and zoom are nice, but if you strive for perfection, prime lenses are THE BEST. In German, die beste in die Welt.

Superb since 1979

The original optical formula dates from 1979. There is a reason it is still in production, although mechanically changed in 1994: An amazing lens that is compact and sharp. Wide open slightly soft but nearly ideal as a portrait lens. Stopped down a bit it is hard to distinguish the quality from newer ASPH designs.

Autofocus is NOT available on any Leica M lens; Many M lenses cannot fit onto the Leica CL body. Wikipedia has a useful write-up; The best CL lenses are the original C 40 f/2, and C 90 f/4 lenses;
