Brand Leica System Leica M

This is the original Summilux-M 50mm f/1.4 ASPH (Leica catalog 11892) in silver chrome, the version Leica made from 2004 until the redesign in 2023. This example was built at Leica's plant in Portugal rather than in Germany. The design is 8 elements in 5 groups with one aspherical surface and a floating element, so it holds contrast wide open and stays consistent as you focus close.

The silver chrome barrel is brass, so at about 470 g it's noticeably heavier than the black anodized version, and it feels solid on a silver M. The hood is built in: it telescopes out and locks with a twist, so there's nothing extra to carry. Rangefinder focus runs to 0.7 m. If you're deciding between this and the newer 0.45 m version, our team can walk you through the differences.

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

The Original ASPH Fifty

Leica's fast standard lens from 2004 to 2023: 8 elements in 5 groups with one aspherical surface and a floating element for close-range correction. Plenty of M shooters still prefer it for its compact size and built-in hood.

Made in Portugal

This lens was built at Leica's factory in Vila Nova de Famalicão, Portugal. It carries the same catalog number and optical design as the German-built examples; collectors like to know which plant a lens came from, so we call it out.

Brass, Hood Built In

Chrome over brass, about 470 g. The telescoping hood slides out and locks in place, and the E46 filter thread doesn't rotate.

Focus and Coding

Rangefinder-coupled focus from 0.7 m to infinity, a 1:11.3 maximum reproduction ratio, half-stop aperture clicks, and 6-bit coding so digital M bodies identify the lens.
