Leica's legendary 50mm f/2 for M-mount — produced across multiple versions spanning decades of optical refinement.
The Leica Summicron-M 50mm f/2 is one of photography's most storied lenses, produced in multiple versions since the 1950s. The M-mount version has been refined through several generations, each improving coatings and optical performance while maintaining the classic Summicron character.
Optically excellent — sharp from f/2.8 with a distinctive rendering that Leica shooters prize. More compact and practical than the Summilux 50mm f/1.4 while delivering exceptional quality. Manual focus with Leica's trademark smooth and precise focus helicoid action.
Leica M mount with 39mm (E39) filter thread on most versions. Approximately 240g depending on version. No autofocus — manual focus rangefinder coupling. Current (V) version has 6-bit coded bayonet for digital M communication. Built-in retractable hood on current version.
Available used across a wide price range depending on version — current production commands premium prices while older versions are more accessible. Check for haze, separation, and fungus on vintage examples. One of the most respected normal lenses ever made.
