Product Details

Leica APO-Summicron-M 75mm f/2 ASPH Lens For Leica M-Series Cameras, Model 11637

Since its launch, the Leica Apo-Summicron-M 75mm f/2 ASPH. has set new performance standards in the Leica rangefinder system. The speed of this powerful lens gives it a particularly wide range of uses from portrait to reportage photography and it counts as one of the best lenses in the M system. Used with the digital Leica M9, the application potential of this telephoto lens is enhanced even further. The focal length extension factor of the digital rangefinder camera turns the compact lens into a powerful telephoto lens with a focal length of 100 mm, making it an ideal partner of ambitious Leica M8 photographers.

The compact Leica Apo-Summicron-M 75mm f/2 ASPH. harnesses all the technical possibilities of today's high-performance optics to achieve a combination of high speed and remarkable imaging quality. It features aspherical surfaces, special glass types with partial anomalous dispersion and floating elements. It is the ideal lens on either an analog or digital Leica rangefinder camera delivering intimate views of scenes, nature, landscapes and people, irrespective of whether they are at infinity or at the close-focus range of the lens. With resolving power well above that of the best colour photo films, it is also a first-rate documentary tool.

Together with the Leica Summicron-M 28mm f/2 ASPH. wide-angle lens, the Leica Apo-Summicron-M 75 f/2 ASPH. offers the best and most elegant high-performance combination available today in 35 mm rangefinder photography.


  • The compact high-performance telephoto lens
    The new LEICA APO-SUMMICRON-M 75mm f/2 ASPH. extends the range of telephoto lenses in the Leica M system with a fast high-performance model that is simultaneously extremely compact.
  • Optimum image quality at close and long range
    To maintain the outstanding imaging performance even at the minimum range of 0.7m - the Summilux-M 75mm only achieves 1m - as on the Summilux-M 50mm ASPH., a so-called floating element is used. This final lens element (no. 6/7) changes its position relative to the rest of the optical system during focusing. While the fundamental technology is common in SLR lenses, to achieve this in a compact M lens with its very limited space, the Leica designers had to develop a brand new, extremely precise adjusting mechanism. Its use allows the benefits of this design to be utilized to the full, while at the same time guaranteeing the familiar silky smooth and absolutely accurate focusing of the M lenses.
  • Quality down the finest detail
    A feature that has now become a standard for Leica lenses has also been included on the new LEICA APO-SUMMICRON-M 75mm f/2 ASPH.: The built-in lens hood, which protects against stray light and dirt, can be locked in its extended position to prevent it accidentally being pushed back in.
