Overview

The Tele-Astranar 250mm f/4.5 is a West German lens from the 1960s, likely made by Piesker and branded by Sterling Howard. It features an M42 mount and a rack-and-pinion focusing lever. Optical performance is not detailed in available sources, but handling is fully manual with no autofocus or electrical contacts, requiring adaptation to modern cameras. It suits photographers interested in vintage manual lenses for deliberate, slow shooting, though its age and lack of modern coatings may limit contrast and sharpness wide open.
