Overview

The Enna München Tele-Ennalyt 135 mm f/3.5 is a vintage telephoto lens produced from 1955 into the 1970s, available in multiple mounts including M42 and Exakta. Its optical design is believed to be 5 elements in 4 or 5 groups, but detailed specifications are scarce. Build quality reflects its era, with a rotating front element for focusing and duplicated aperture scales reminiscent of rangefinder lenses. User samples on cameraderie.org show moderate sharpness and noticeable chromatic aberration at wider apertures, improving when stopped down. The lens suits photographers interested in classic rendering and manual operation on mirrorless cameras, but it is not recommended for those seeking modern optical performance.
