Brand Leica System Leica M

The Leica Summilux-M 50mm f/1.4 ASPH. is the reference-standard fast fifty for the M system — a natural 50mm perspective with a bright f/1.4 aperture for available-light photography and selective-focus images with shallow depth of field. Its advanced optical design delivers high-contrast, high-resolution detail across the entire frame, even wide open.

This current generation focuses closer than ever, down to 0.45 m, and uses an eleven-blade diaphragm for exceptionally round, creamy bokeh. In black anodized finish, with an integrated pull-out hood and compact all-metal build, it's the standard lens our team reaches for again and again. Stop by and see why it earns its reputation.

Buy from an authorized Leica dealer like Camera West to ensure a genuine product with full manufacturer warranty and expert support.

The Reference Fast Fifty

A natural 50mm perspective with a 45.4° diagonal angle of view that closely matches human vision, paired with a fast f/1.4 aperture ideal for available-light work and selective focus. The lens delivers high-contrast, high-resolution imaging across the whole field, even at maximum aperture.

Eleven Blades, Creamy Bokeh

An eleven-blade diaphragm, up from nine on the predecessor, produces an even rounder aperture and beautifully smooth bokeh. A floating element preserves imaging performance all the way to the minimum focusing distance.

Closer Focusing to 0.45 m

This generation focuses down to 0.45 m: rangefinder-coupled to 0.7 m, then extended into the 0.7–0.45 m range via Live View, the Visoflex, or the Leica FOTOS app — opening up tighter compositions and close-up detail.

Compact, Built in Germany

With an integrated, extendable pull-out hood, an E46 filter thread, and a compact all-metal build (approx. 377 g), it stays true to the M ideal. The Leica M bayonet with 6-bit coding ensures full compatibility with digital M cameras. Made in Germany.
