Overview

The Leitz Wetzlar Super-Angulon 21 mm f/3.4 is a compact lens with a recessed design that causes compatibility issues on digital rangefinders like the Leica M10, obstructing the internal light meter and requiring external metering or Sunny 16 Rule. Optically, it is considered one of the best M-mount lenses, but its handling is challenging for those unfamiliar with manual metering. It suits experienced photographers willing to work around its limitations for exceptional image quality.
