The Leica 50mm f/2 Summicron-M is the reference standard 50mm: a compact, superbly built double-Gauss lens that is tack-sharp wide open while retaining genuine character and gorgeous color, all without aspherical or apochromatic elements. It's for the photographer who wants a classic Leica standard lens with beautiful rendering and impeccable handling — but buyers should know it commands a steep price, and modern Voigtlander alternatives now offer sharper or more affordable performance.
