How Much Is a Used Leica Summicron-R 90mm Worth? (2026 Price Guide)

Optically the versions are the same five elements in four groups, so the practical choice is the mount and filter system. A 3-cam or ROM example with the later E55 filter thread is the most flexible for both film bodies and adapters. The earliest Series VII filter copies are fine optically but use harder-to-source filters.

A 3-cam or ROM lens mounts on all Leicaflex and Leica R bodies and on the Leica R-Adapter L for SL, SL2, and CL mirrorless cameras. Early 2-cam copies meter stop-down only on later film bodies and should not go on the R-Adapter L, which is rated for lenses from 1976 onward; ROM versions fit only R3-era and later bodies.

Both are f/2 90mm portrait lenses, but the R version is a longer-bodied SLR design built for reflex focusing, while the M lens is shorter for rangefinder use. On mirrorless the R lens, with its built-in hood and lower used prices, is an easy and affordable portrait option.

Check for haze, fungus, and element separation, confirm the built-in hood slides and locks, and make sure focus is smooth and the aperture blades are clean. Verify the cam or ROM configuration matches your body or adapter.
