Overview

The Leitz Wetzlar Super-Angulon-R 21mm f/3.4 is a symmetrical ultra-wide-angle lens designed by Schneider for Leica, introduced in 1963. Its compact design recesses glass behind the mount, causing compatibility issues on digital rangefinders: the barrel obstructs the internal light meter, requiring external metering or Sunny 16 Rule. Optically, it offers distinctive character and performs well on film, but lacks the 'pop' of modern glass. Build quality is high, but handling is challenging for digital users. It suits film shooters who appreciate classic rendering and are comfortable with manual metering.
