How Much Is a Used Leica Summicron-R 35mm Worth? (2026 Price Guide)

Version 2 (1976 to 2009) is the one most buyers prefer: it is smaller and lighter at six elements in six groups, performs at least as well, and is easy to find with a 3-cam or ROM mount. Version 1 (nine elements in seven groups) is a heavier early design usually found in 2-cam or 3-cam form and is more of a collector choice.

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

Adapted to a full-frame mirrorless camera with the R-Adapter L it stays a 35mm, giving a true wide-angle with the Leica rendering at a fraction of native M wide-angle prices, which is a big reason R glass is sought after now. On APS-C it becomes a roughly 50mm-equivalent normal.

Check the elements for haze, separation, and fungus, confirm smooth focus and clean aperture blades, and verify the cam or ROM configuration matches your camera or adapter. On Version 1 also weigh the larger size against Version 2 before buying.
