Overview

The A. Schacht Ulm Travenar R 135mm f/3.5 is a 4-element Sonnar-type design by Ludwig Bertele, praised for its build quality: "mechanical and haptic delicacies". Optically, it is "very convincing" and performs well, though not "technically outstanding". One user found it capable of winning a best MF lens contest, while another dismissed it as "crap". It suits enthusiasts seeking a well-built, affordable vintage portrait lens with a classic rendering.
