Overview

The Weltblick 135mm f/2.8 Auto Tele (M42, 55mm filter) is a manual-focus lens praised for its sharpness and pleasing bokeh wide open (Pendragon67). It exhibits good contrast and resolution, though purple fringing may appear in high-contrast scenes. Build quality is solid, with an 8-blade aperture and all-metal construction. The lens is well-suited for Canon DSLR users seeking an affordable, vintage telephoto prime, especially on APS-C bodies like the 600D (Pendragon67). It offers excellent value for its optical performance, though it lacks modern coatings.
