Description — Leica 11680
The Leica Summarit-M 50mm f/2.4 is a prime lens designed specifically for the Leica M rangefinder camera system, covering a full-frame image circle at a 50mm focal length. Its f/2.4 maximum aperture delivers reliable performance across a range of lighting situations, while the manual focus operation keeps the shooting experience true to the rangefinder tradition. At just 190g, the lens is impressively light, reducing fatigue during long days on the street or while traveling.
The 46mm filter thread makes it straightforward to attach commonly available filters without the need for expensive step-up adapters. Image stabilization is not present, so sharp results depend on good technique — but the low weight helps here too. This is a lens built around the philosophy of simplicity and precision: a single focal length, a clean optical experience, and seamless integration with Leica's M-mount ecosystem.
