The LEICA Super-Elmar-M 18mm/f3.8 ASPH is a compact lens despite its very large angle of view. It offers excellent imaging performance. Vigneting and distortion are hardly visible with the Leica Super-Elmar-M 18mm/f3.8 lens in photographical practice, aspects usually difficult to master in the design of super wide angle lenses. This lens offers extremely sharp, crystal-clear and evenly illuminated pictures from edge to edge. The lens is equipped with a rectangular, patented lens hood, contributing substantially to the compact dimensions.
