Leica's legendary fast 50mm for M — the Summilux f/1.4 across multiple versions spanning decades.
The Leica Summilux-M 50mm f/1.4 is one of photography's most iconic lenses — produced in multiple versions since the 1960s. The Summilux designation indicates f/1.4 maximum aperture — one stop faster than the Summicron f/2.
Optically varies by version — pre-ASPH versions have distinctive vintage character while the ASPH (2004+) delivers modern sharpness. All versions share the Summilux rendering quality that defines Leica portraiture. Manual focus with rangefinder coupling.
