The Isco-Gottingen Edixa-Westanar 50mm f/2.8 is a normal prime lens for 35 mm SLR cameras with the M42 screw mount.
The lens is single-coated. The lens body is made of chrome-plated brass.
This is the later version of the Isco-Gottingen Westanar 50mm f/2.8 with a more usual aperture control.
The optical design:reversed Tessar, cemented doublet in the front position. That's why the lens is good at close range and is not so good at infinity.
Filter diameter - 41 mm
