LEICA SL 35MM F/2 APO-SUMMICRON ASPH

Leica APO-Summicron-SL 35mm f/2 ASPH.

As a moderate wide-angle prime, the APO-Summicron-SL 35mm f/2 ASPH. is almost a universal lens. Its fast autofocus, robust design and construction and exceptional imaging quality make it an outstanding lens for reportage and a convincing choice for other areas of photography such as architecture, landscapes, portraiture and studio work. It is perfectly matched to the cutting-edge SL-System and has been conceived for a long working life under professional shooting conditions.

AF System with Dual Syncro Drive™

The AF system of the Summicron-SL lenses is fast, precise, and almost silent. They thank their outstanding AF performance figures to the autofocus drive unit they share. These are limited only by the mass of the lens elements moved when focusing, the travel from infinity to the closest focusing distance and, of course, the amount of space available. In order to preserve the compact dimensions of the lenses, the integration of these components must follow an integral approach.

In the Summicron-SL lenses, the drive units installed are extremely powerful and robust stepping motors with Dual Syncro Drive™. Thanks to these, the entire focusing throw can be traveled completely in fractions of a second. This means that the Summicron-SL lenses achieve values that are among the best in the full-frame system segment in terms of speed, precision, and noise emissions. 

Higher Contrast for greater perceived depth

With an initial aperture of f/2, the SL-Summicron lenses are significantly more compact than faster lenses, but still allow photographers to work with similar depth of field. The reason for this is contrast: the zone of highest contrast is perceived by viewers as being sharp, while zones with lower contrast are regarded as being unsharp.

In the case of SL-Summicron lenses, this difference in contrast is considerably higher than that of conventional lenses: sharply focused objects show much higher contrast than objects that are out of focus. This means that objects “snap” more distinctly out of the foreground or background and more effectively isolate the subject. This creates a three-dimensional visual effect with very impressive apparent depth.
