Overview

The WEP Auto Telon 135mm f/2.8 is a vintage telephoto lens with a simple optical design. It offers decent sharpness in the center but suffers from softness and chromatic aberration at the edges, especially wide open. Build quality is typical for its era: all-metal construction with smooth focusing, though the aperture ring may feel loose. It suits photographers interested in retro character or budget telephoto options, but those seeking modern edge-to-edge sharpness should look elsewhere.
