Product Info for Leica Super-Elmar-M 18 mm f/3.8 ASPH Lens
Leica Super-Elmar-M 18 mm f/3.8 ASPH 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 by Leica. 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.
The Leica Super ElmarM 18 mm f/3.8 ASPH. will help you capture the expansiveness of space like few other tools. Nominally larger than a standard lens, it boasts an extreme angle of view of up to 100 degrees and reaches far into the field of super wide angle lenses, at the same time guaranteeing the outstanding lens qualities that are typical for Leica. The Leica Camera Accessory broadens the horizon not only in architecture and landscape photography but in many other areas as well.
This camera accessory by Leica successfully merges ambitious wide angle photography with the very best of optical quality and compact design. This is achieved thanks to a patented, spacesaving, yet extremely effective lens hood. The lens corresponds to a universal 24 mm wide angle lens when mounted on a Leica M8 model of Digital Camera Accessories and a super wide angle lens with an impressive angle of view when mounted on an analogue Leica M model. Its retrofocus-like architecture features eight lens elements of which one boasts two aspherical surfaces to ensure outstanding image quality already at open aperture.
