Leica SUMMILUX-M 35 mm f/1.4 ASPH. User Manual

LEICA SUMMILUX-M 35 mm f/1.4 ASPH.
1
The outstanding imaging performance of this very compact lens is due to the application of aspherical technology. It delivers high
contrasts, excellent detail rendition over the entire image area, good field flatness, and it has extremely low coma. Because all
these qualities remain practically unchanged in the close-up range down to 0.7 m (28 in), this Summilux lens is the universal wide-
angle lens. Its applications range from portraits at medium distances all the way to landscape photographs. The 35 mm lenses are
already considered to be standard lenses in the Leica M system. With its large aperture, this lens masters all photographic situa-
tions superbly.
