Leica announced the new APO-Summicron-SL 35 mm f/2 ASPH. Lens under the L-Mount segment for the Leica SL mirrorless camera, as well as all cameras released as part of an alliance between Leica, Panasonic, and Sigma.

The company claims to have paid particular attention to preventing glare and ghosting in the lens. Thanks to the optical and mechanical design, as well as to the coatings on each lens surface, the lens provides a high level of image quality throughout the entire field of the frame, even with an f/2 aperture.

The front element of the lens has Aquadura coating, which repels dust, moisture and water spray. Inside the lens (and all Summicron-SL lenses) there is a powerful DSD (Dual Syncro Drive stepping motor can be travelled completely in only around 250 milliseconds, providing ultra-fast focus.

Inside it, a total of 13 extremely complex lenses ensures the very highest levels of the image quality attributes so typical for Leica: natural skin tones, soft transitions into the bokeh, outstanding contrast in details and consistent sharpness from corner to corner and edge to edge of the distortion-free image.

It features a totally new concept for manual focusing in which a ring magnet with alternating north-south magnetization is embedded in the focusing ring. The magnetic field changes its polarity when the ring is turned. A sensor monitors the status of the magnetic field and sends the data to the main processor. The drive then shifts the lens to the corresponding focusing position on the basis of the angle of rotation and the rotational speed – this, in turn, enables even faster and more precise manual focusing.
