Concentrated Quality
The 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.
Technical Details
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.
Wide Angle with Wide-Ranging Vision, Clarity in Every Composition
The Super-Elmar-M 21 mm f/3.4 ASPH. was engineered for photography that demands uncompromising image quality. An M-Lens that adds barely any weight, yet offers remarkable visual impact. With its expansive 91-degree angle of view, it captures wide spaces, renders architecture free from distortion and presents landscapes with striking clarity. This lens embodies optical mastery and documentary precision – modest in appearance, yet striking in expression.
The Strengths of the 21 mm Leica M-Lens
The Super-Elmar-M 21 f/3.4 ASPH. stands out for its meticulous detail, linear rendering, and exceptional suppression of glare and reflections. Perfectly suited to architectural photography, street reportage and sweeping nature scenes. The moderate f/3.4 lens speed allows for an exceptionally compact design that pairs seamlessly with M-System cameras. At the same time, the lens maintains exceptional robustness and durability, even through extended use or under challenging conditions. Its natural rendering, coupled with precise correction of optical aberrations, makes it a preferred choice for those who value uncompromising lines and time-tested quality.
Design of the Super-Elmar-M 21 f/3.4 ASPH.
Eight lenses arranged in seven groups – including an aspherical lens – deliver a virtually distortion-free image with uniform sharpness across the entire field of view. Special glass elements featuring anomalous partial dispersion minimize color aberrations, even with high-contrast subjects. Its close focus distance is 0.7 meters. The lens is supplied with a rectangular metal lens hood that not only offers effective protection against stray light, but also accentuates the clear, technical design of this M-Lens with E46 filter thread.
