Leica has announced the Super-Elmar-M 21mm f/3.4, a wideangle prime for its M-series rangefinder cameras. Weighing in at less than 10 ounces, it's extremely compact at just under 2 inches in length. It has a minimum focus distance of 0.7m, and uses a dual-sided aspheric element and 4 anomalous partial dispersion elements in its optical construction. On the M8 camera it offers an angle of view equivalent to a 28mm lens. It will be available from June 2011 at a price of £2025.

Leica announces Super-Elmar-M 21mm f/3.4 ASPH.

Compact M lens with improved imaging performance sets new standards in wide-angle
photography

21 June 2011, 18.00 GMT: Leica has today added a new, high-performance wide-angle lens to its portfolio of short focal length lenses for Leica M cameras. The Leica Super-Elmar-M 21 mm f/3.4 ASPH. sets new standards in imaging performance and is characterised by its particularly compact size and suitability for a wide range of photographic situations. Whether used for photojournalism, architecture or landscape photography, the Leica Super-Elmar-M 21 mm f/3.4 ASPH. provides photographers with an extremely small, light and versatile wide-angle lens, particularly suitable for travelling.

The performance of the Leica Super-Elmar-M 21 mm f/3.4 ASPH. is reminiscent of one of the all-time favourite classics amongst M lenses, the Leica Super-Angulon-M 21 mm f/3.4. This much-praised lens was an integral part of the Leica M lens portfolio from 1963 to 1980, and made its name and reputation as an ideal tool for available light photography and photojournalism. Even today, the Super-Angulon-M 21mm f/3.4 is extremely popular and one of the most sought-after M lenses amongst connoisseurs of fine optics.

The new Leica Super-Elmar-M 21 mm f/3.4 ASPH. is a worthy successor, with further improvements over the already outstanding performance of its predecessor. The lens reveals its excellent reproduction of detail and superior contrast at maximum aperture. Of particular note are the extremely effective flare characteristics of the Leica Super-Elmar-M 21 mm f/3.4 ASPH., which allow the capture of fascinating 'contre-jour' images with absolute clarity and contrast.

The intricate optical design and construction of the lens are responsible for its outstanding sharpness and imaging qualities. The Leica Super-Elmar-M 21 mm f/3.4 ASPH. is constructed with eight lenses in seven groups. At the same time, the use of one lens element with two aspherical surfaces and four lenses with anomalous partial dispersion ensure that aberrations are reduced to an absolute minimum.

As with all Leica lenses, the Super-Elmar-M 21 mm f/3.4 ASPH. was designed and developed by Leica specialists in Solms, Germany, and represents the perfect combination of optical and technical expertise. Particularly reliable and with enduring value, every Leica lens is manufactured from only the highest quality materials and is assembled with meticulous precision, completely by hand. The combination of cutting-edge technologies and extremely thorough manufacturing processes guarantees consistently excellent quality.

The Leica Super-Elmar-M 21 mm f/3.4 ASPH. is supplied with a high-quality, all-metal lens hood, which should be mounted at all times. The hood not only protects the lens effectively against reduction of contrast by extraneous light, but also against damage and the accumulation of dirt on the front lens element.
