The lens that defined what a standard prime should be — the Summicron-M 50mm f/2 has remained in continuous production in essentially the same optical formula since 1979 because no improvement has been necessary. It delivers a natural full-frame field of view with outstanding sharpness from f/2, a silky focus ring with perfect damping, and the kind of compact dimensions that feel inevitable on any Leica M body. It is the benchmark against which every other 50mm prime is measured. Rangefinder-coupled for manual focus on all Leica M-mount cameras.
Unchanged in forty-five years because nothing needs changing — the Summicron 50mm is the reference standard prime that every other 50mm is judged against.
