Leica Super-Elmar-M 21mm f/3.4 ASPH.
The new Leica Super-Elmar-M 21mm f/3.4 ASPH. is characterized by superb imaging performance and amazingly compact construction. This powerful combination makes it ideal for many applications, such as landscape or photojournalistic photography. Even at maximum aperture, the lens delivers outstanding rendition of details and optimum contrast up to its closest focusing distance.
The sophisticated design and construction comprises eight elements - including one with two aspherical surfaces and another four with anomalous partial dispersion - and plays a decisive role in reducing distortion and vignetting to an absolute minimum. The lens is supplied with a metal, screw-mounted lens hood to prevent flare effects and ensure perfect image sharpness.
To meet the requirements of digital photography, the Leica Super-Elmar-M 21mm f/3.4 ASPH is a benchmark in all optical performance characteristics. The stray light optimization was implemented on a very high level, allowing for backlit shots with crystal clear contrast. The design of the metal lens hood matches the appearance of the current wide-angle lenses of the Leica M system. This lens hood is also compatible with the Leica Super Elmar-M 24 mm f/3.8 ASPH and the Leica Summilux-M 35mm/1.4.
