Description — Leica 11254
The Leica 11254 Summicron-R is a 90mm prime lens built for the Leica R mount system, providing full-frame coverage for compatible bodies. Featuring a f/2 maximum aperture, this telephoto prime offers solid performance in available-light situations and allows for meaningful background separation at this focal length. The lens is a manual focus design — there is no autofocus — placing full control in the hands of the photographer through direct interaction with the focus ring.
Weighing 560g and accepting 55mm front filters, it is a practical size for a full-frame f/2 telephoto prime. There is no image stabilization in this lens. The 3rd Cam designation is an important detail for buyers, as it determines which Leica R bodies this lens will properly communicate with.
This is a prime lens with a fixed 90mm focal length, dedicated to a single perspective without the optical trade-offs of a zoom design.
