(none) A.Schacht Ulm 135mm f/3.5 R Travenar Semi-Auto Lens for M42 Screw Mount, Black/Chrome Review

The A.Schacht Ulm 135mm f/3.5 R Travenar is a vintage manual focus telephoto lens designed for M42 screw mount cameras. Built by the historic German optics manufacturer Schacht, this semi-automatic design offers classic rendering and mechanical simplicity for photographers working with legacy film or adapted digital bodies. The 135mm focal length is a traditional portrait and medium-telephoto choice, and the f/3.5 maximum aperture is typical for lenses of this era.

As a used bargain-grade offering from KEH, this lens comes at an attractive price point for those exploring vintage glass or building out an M42 collection. The semi-auto diaphragm allows for easier shooting than fully manual designs, though it still requires adapter use on modern mounts. Condition will vary, and optical or cosmetic wear is expected at this grade. It suits experimenters, collectors, or budget-conscious shooters willing to work with older glass for its unique character and low cost.
