Overview

The Leitz Wetzlar Super-Angulon 21mm f/4 is a compact, brass-built lens made by Schneider for Leica. It offers excellent sharpness edge-to-edge with no visible distortion, though corner light falloff is typical for ultrawide designs. Its 39mm filter thread is a convenience. However, on digital M cameras, the recessed rear element blocks the internal meter, requiring external metering or Sunny 16. It suits photographers comfortable with manual metering who value its unique rendering and compact size.
