Overview

The Isco Gottingen Edixa Westanar 135mm f/3.5 is a vintage telephoto prime with solid build and smooth focus. Optically, it offers good resolution and sharpness, with a 15-blade aperture producing very nice bokeh. Weaknesses include evident chromatic aberration wide open, though it clears by f/5.6, and a long minimum focus distance. The lens lacks coatings, so a sunshade is recommended. It suits users seeking a budget portrait lens with unique rendering, but may be less ideal for those wanting modern convenience or close focusing.
