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 21
mm 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.
