LEICA SUMMILUX-M 35 mm f/1.4 ASPH.
1
The LEICA SUMMILUX-M 35 mm f/1.4 ASPH. is a further revised version of the popular wide-angle lens of the Leica M rangefin-
der system. Thanks to the latest developments in the fields of optics and precision engineering, the new 35 lens sets a whole new
standard in the fast wide-angle lens portfolio. Regardless of whether it's a matter of selective focus in the close-up range, high-
contrast available light applications or landscape shots with immense depth of field, the lens delivers persuasive arguments in
any situation. In comparison with its predecessor, the new LEICA SUMMILUX-M 35 mm f/1.4 ASPH. now incorporates a floating
element: the lenses behind the aperture blades are constructed as a floating group that changes its position relative to the front
lens group during focusing to ensure that the LEICA SUMMILUX-M 1:1.4/35 mm ASPH. achieves equally outstanding imaging per-
formance at closer focusing distances. Another new feature is a full-metal, rectangular, screw-mount lens hood that contributes
significantly to the even more compact dimensions of the lens. 
Even wide open, the LEICA SUMMILUX-M 35 mm f/1.4 ASPH. reveals performance characteristics without precedent in the field
of compact 35 mm lenses: outstanding imaging performance over the entire focusing range, from infinity to minimum focus,
excellent contrast, even in the finest structures, superb rendition of details across the entire image field, good field flattening
and, stopped down to f2 and onwards, almost complete freedom from coma effects. It is hardly possible to improve this excellent
optical performance by stopping down.
