About this lens

Carl Zeiss Jena Sonnar 5cm f/1.5 (LTM)

This profile covers documented Carl Zeiss Jena 50mm f/1.5 Sonnars in Leica thread mount. Leitz Photographica Auction identifies example 2725655 as having an original, rangefinder-coupled M39 screw mount.

Mount and identity

The LTM lens has a focusing mount for Leica screw-mount rangefinders. It is distinct from the Contax RF 50mm f/1.5, which relies on the camera focusing mechanism, and from the 5.8cm and 6cm Sonnars. Neither an M adapter nor a T coating mark changes the nominal focal length.

Production scope

This entry does not assign all LTM examples to a single production batch or claim a uniform barrel specification. Coating, materials and provenance require examination of the individual lens. No separate post-war generation is created solely from a seller description. Production dates, weight, dimensions and minimum focus remain unspecified pending mounting-specific evidence.

Collector notes

Verify the 5cm engraving, Leica focusing mount and rangefinder cam, and distinguish historical LTM examples from later custom conversions. A 5cm LTM listing must not be matched to the separate 6cm profile.
