Overview

The Enna Tele Ennaston 135 mm f/3.5 is a vintage telephoto lens produced from 1955 to the late 1970s, available in multiple mounts including M42, Exakta, and Enna Sockel. Optically, it features a 5-element design, but detailed specifications are sparse. Build quality is typical of the era, with a rotating front element for focusing and duplicated aperture scales reminiscent of rangefinder lenses. Handling is fully manual, making it adaptable to mirrorless cameras with a simple adapter. It suits photographers interested in vintage character and manual operation, though optical performance details are limited.
