Overview

The Isco-Gottingen Tele-Westanar 180mm f/4 lens for M42 mount is described as having clean, clear glass for its age, but with a notable optical flaw: a circular brighter area in the center of images. It has a small nick on the front element, and the focus feels dry and loose, while the aperture works but feels clunky. The barrel shows moderate to advanced wear. This lens is suited for collectors or those seeking a project lens for parts or repair, given its optical and mechanical issues.
