Fast Wide-Angle Prime. The Leica 21mm f/2 ASPH Super-APO-Summicron-SL’s wide-angle focal length and bright f/2 maximum aperture make it exceptional for landscapes, interiors, architectural shooting, studio work, and even photojournalism.
Apochromatic Optical Design. The 21mm’s apochromatic eleven-group/fourteen-element optical construction incorporates multiple anomalous partial-dispersion glass elements, three of which are aspherical. All that glass means virtually nonexistent chromatic aberrations and color fringing for exceptionally sharp, clear, and color-accurate images from the widest aperture setting.
Focus, Focus, Focus. The Dual Synchro Drive autofocus system provides fast, accurate, nearly silent performance, and the 8.3-inch minimum focusing distance lets you get in close.
High-Quality Build. This lens’s compact, lightweight design makes it great for everyday shooting situations, and the front of the barrel is threaded to accept 67mm filters.
