The Leica Summicron-M 50mm f/2 (Black) is a version of Leica's legendary standard prime without the 6-bit digital coding — indicating an earlier production or film-era version. The Summicron 50mm is one of photography's most respected normal lenses.
Optically excellent — the Summicron formula delivers outstanding sharpness with Leica's signature rendering. Sharp from f/2.8 with beautiful tonal gradation. Multiple versions exist across decades. Manual focus with rangefinder coupling.
Leica M mount without 6-bit coding — film-era production. Filter thread varies by version. Compact and lightweight. All-metal construction. The non-coded version works on digital M bodies but without automatic lens detection.
Available used at professional to luxury prices — pre-6-bit versions slightly cheaper. Works on all M bodies — digital requires manual lens selection in menu. The 6-bit coded version is preferred for digital. For film M users or digital users comfortable with manual lens selection.
