How Much Is a Used Leica Summar 50mm Worth? (2026 Price Guide)

Leica used an unusually soft front element on the Summar, and it scratches easily, so a high proportion of surviving lenses show fine cleaning marks or a network of light scratches. Clean examples are relatively rare and command a premium, while a scratched lens can still be a usable character lens.

Inspect the front element under raking light for scratches and cleaning marks, and check inside for haze, fog, and any separation. All Summars are uncoated, so heavy haze on top of that will make images very low in contrast. Confirm the collapsible mount locks and the aperture is clean.

The Summitar superseded the Summar in 1939 with a coated, more complex design that controls flare and vignetting far better and is sharper into the corners. The Summar is chosen for its softer, swirlier vintage rendering rather than outright performance.

Yes. It is a 39mm screw-mount lens, so an LTM-to-M adapter mounts it on a Leica M body, and further adapters allow mirrorless use. Note the swirly rendering and low contrast are most pronounced wide open, which is much of the appeal.
