Leica Super-Elmar-M 21mm f/3.4 ASPH. Lens

The Leica Super-Elmar-M 21mm f/3.4 ASPH. is a highly adaptable wide-angle prime lens designed for Leica M-mount rangefinder cameras. This exceptional lens is distinguished by its advanced optical construction and remarkably slim profile. It incorporates one double-sided aspherical element along with four elements that exhibit anomalous partial dispersion, effectively reducing spherical and chromatic aberrations as well as distortions, while ensuring consistent sharpness across the entire aperture range. Additionally, the aspherical element aids in achieving a compact design, and the manual focusing mechanism allows for capturing subjects as close as 2.3 feet.

• Wide-angle prime utilizes one double-sided aspherical element to reduce spherical aberrations and distortion for improved sharpness throughout the aperture range.
  
  
• Four anomalous partial dispersion glass elements help reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
  
  
• Aspherical element also contributes a compact design measuring 2.1 x 1.7".
  
  
• Manual focus design affords a minimum focusing distance of 2.3'.
  
  
• The front of the lens has 46mm-diamter threads to accept optional filters and the lens is male threaded to accept the included lens hood.
