Overview

The Leitz Wetzlar Super-Angulon-R 21mm f/4 is a symmetrical wide-angle lens designed by Schneider for Leica, introduced in 1963. Its optical formula protrudes into the camera body, which can cause issues on digital rangefinders. On film, it is praised as a 'cracking bit of glass' with interesting character traits, though it lacks the 'pop' of modern wide-angles. Build quality is typical of Leica-era lenses. It suits film shooters seeking classic rendering, but not those wanting modern sharpness or digital compatibility.
