This is the first Leica M lens with a specifically patented ‘floating element’ used to maintain imaging performance at a very high level even in close-focus ranges down to 0.7m.
• During focusing, the rear most optical component (elements 7/8) moves relative to the rest of the optical system and produces brilliant image quality in near focus ranges.
To maximize the benefits of the ‘floating element’ an extremely precise adjusting mechanism has also been utilized that had to fit into the restricted space inside this compact M-lens
At full aperture, the LEICA SUMMILUX-M 50mm f/1.4 ASPH. offers high contrast rendering even for the finest structures. This performance can only be raised slightly by stopping down. Another notable feature of this lens is that it is virtually distortion-free.
The normal vignetting for such high-speed lenses at full aperture is strongly reduced by stopping down slightly. Furthermore, the use of the most advanced coating technology ensures a high degree of anti-glare.
The LEICA SUMMILUX-M 50mm f/1.4 ASPH. also offers special features in terms of its handling: The built-in lens hood not only provides protection against stray light and dust, it can also be locked in the extended position to guard against accidental retracting.
In addition to the familiar knurled ring, the lens is equipped with a finger grip that allows easy focusing using one finger. The balanced proportions of the lens also provide comfortable usage for longer periods of time.
6-bit lens identification code
The digital Leica M writes the lens data it reads off the code to the EXIF file and utilizes this information to process the image data for optimal image quality. In the digital Leica M, this allows compensation of system-immanent vignetting customized according to the lens attached. Therefore, when using the digital Leica M, this feature results in even a slight improvement of the accustomed high image quality produced by Leica M lenses.
In flash mode, the output of the pre-flash is determined by the focal length information supplied by the 6-bit code.
