Overview

The A. Schacht Ulm M-Travenar R 50mm f/2.8 is a Tessar-type macro lens from the 1960s, designed by Ludwig Bertele. It offers gentle sharpness with delicate rendering and pleasant bokeh, though resolution is not as high as Gauss or triplet designs. Optically, it performs best at close to midrange distances, with high contrast and good color; wide open it is sharp, and at f/4 it is even better. Build quality is high, with a distinctive red depth-of-field scale, but the lens extends significantly for 1:1 macro. It suits photographers seeking a vintage look with soft yet sharp images, especially for macro and portrait work.
