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