50mm · f/1.8
The A. Schacht Ulm Edixa-S-Travelon-A 50mm f/1.8 is a rare lens, especially in the U.S., often found on Edixa cameras (MFlenses). It is very sharp by f/2.8–f/4, but soft wide open, with edgy bokeh typical of Schacht lenses (Mos6502). Color and low-light performance are good, though not as sharp as top German 50s of its era (calvin83). Build quality is decent, but aperture blades can become oily and sticky (Mos6502). It suits Edixa SLR users seeking a native normal lens, but optically it is on par with cheaper alternatives like the Takumar 55mm f/1.8 (Mos6502).
