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.
75mm - The universal portrait focal length
With its more natural perspective compared to a 90mm focal length, where depth is reproduced with less compression, it is ideally suited for many applications including reportage and portraits - particularly in smaller rooms. Its small dimensions result in not only outstanding handling but also a Leica M viewfinder image that is almost completely free of shadowing, thus allowing totally undisturbed viewing of the subject. Whether you are using full stop to deliberately "isolate" critical parts of the subject or working in high-contrast available light - both very common in applications with these focal lengths - or stopping down for sharp reproduction of more extensive areas of the subject, the LEICA APO-SUMMICRON-M 75mm f/2 ASPH. is convincing in any situation: At full stop, it offers excellent contrast reproduction, even for very fine structures. This performance can only be slightly improved by stopping down. Another outstanding feature is the extremely low distortion of only 1%. The vignetting that is normal for fast lenses at their maximum opening - up to approx. 1 stop in the corners of the image here - is further reduced by stopping down: At f/2.8, it is negligible, except for the extreme corners and at f/5.6 it is negligible even in the corners.
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.
