Fast ultra-wide-angle lens

The Super-APO-Summicron-SL 1:2/21mm combines the worlds first APO lens with 21mm with latest technology made by Leica.

The 21mm focal length can be used flexible for several use cases -especially for landscape, interior, street and architectural photography.

Natural skin tones, smooth transitions into bokeh, exceptional contrast in details, and edge-to-edge sharpness are a matter of course for Leica APO-Lenses.

The universal wide-angle zoom
Interiors, group portraits, landscapes, and more: This Vario lens expands the options offered by the SL-System into the realm of wide-angle photography and ideally complements the existing portfolio of Vario lenses for the Leica SL.

In addition to excellent imaging quality throughout the entire range of focal lengths and at all apertures, the high-performance lens also offers simultaneously fast and quiet autofocus. This is driven by a specially developed focusing drive comprising a stepping motor and linear positioning and moves a single, very light focusing element that, due to its low mass, contributes to the high focusing speed.

The newly designed optical system contains a total of 18 elements in 12 groups. These include two asphericals for the correction of monochromatic aberrations. Three elements made from glass with anomalous partial dispersion correct chromatic aberration, while an improved mount geometry and high-quality coating ensure optimum suppression.
