Excellent Low-Light Performance. The Leica 50mm f/1.4 Summilux-M ASPH is an updated version of the classic Leica 50mm Summilux’s extraordinary f/1.4 speed. It permits usable shutter speeds even in poor light situations, making it particularly useful in reportage photography.

Advanced Optical Design. It provides cutting-edge technology: aspherical lenses, glass with anomalous partial dispersion, glass with a high refraction index and a floating element. It provides close-focus abilities, excellent sharpness at wide-open apertures, has a built-in, lockable hood, and is digitally encoded with automatic, in-camera correction of vignetting on the Leica M10 / Leica M-E Typ 240
