LEICA SUMMILUX-M 50 mm f/1.4 ASPH. 1
Leica Camera AG has unveiled a new highspeed standard lens for the Leica M System offering maximum imaging performance:
the new LEICA SUMMILUX-M 50mm f/1.4 ASPH. It supersedes the predecessor lens with the same speed, which, notwithstanding
a few minor modifications, had been part of our range since 1962. The aim of this new development was to create a reference lens
to push the technical boundaries of photography using standard focal lengths into new dimensions. The LEICA SUMMILUX-M 50mm
f/1.4 ASPH. delivers virtually the same outstanding performance throughout all apertures and focus settings. Whether using selec-
tive focus at close range, high-contrast available light applications or an extended depth of field to capture landscapes, the
LEICA SUMMILUX-M 50mm f/1.4 ASPH. handles every situation with ease. It therefore delivers on its promise to be a genuine
universal lens in impressive fashion. Every innovation currently available in lens technology – aspherical lenses, glass with anoma-
lous partial dispersion, glass with a high refraction index and a floating element – has been combined to create a lens that sets the
new standard in this focal length class.

MTF graphs
The MTF is indicated both at full aperture and at
f/5.6 at long taking distances (infinity). Shown
is the contrast in percentage for 5, 10, 20 and
40 lp/mm accross the height of the 35 mm film
format, for tangential (dotted line) and sagittal
(solid line) structures, in white light. The 5 and
10 lp/mm will give an indication regarding the
contrast ratio for large object structures.The
20 and 40 lp/mm records the resolution of finer
and finest object structures.
