Super-ELMAR-M 18mm camera lens

The Leica Super-ELMAR-M 18mm f/3.8 ASPH. camera lens features a lens element with two aspherical surfaces, ensuring outstanding optical performance across the image plane and at all f-stops. With the lens set to maximum aperture and mounted on a traditional Leica M or digital LEICA M8 model, vignetting - an effect which is inherently more prevalent with super wide angle lenses - amounts to a nominal 2.3 stops or 1.7 stops on an M8. Stopping down to f/5.6 reduces the vignetting to a value of 1.3 or 1 respectively. Maximum distortion, in turn measures only 1.8 percent and is virtually undetectable to the human eye. The LEICA ELMAR-M 18mm f/3.8 ASPH, not only offers optimum image performance, it has compact dimensions - for its focal length - and provides all Leica M users with an economical
introduction to super wide-angle photography.
