The Leica Summilux-M 50mm f/1.4 ASPH. delivers virtually the same outstanding performance throughout all apertures and focus settings. Whether using selective focus at close range, high-contrast available light applications or an extended depth of field to capture landscapes, this lens handles every situation with ease.\n\nEvery innovation currently available in lens technology - aspherical lenses, glass with anomalous 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.\n\nAn extremely fast standard lens that is used a great deal in reportage photography. Its extraordinary speed of f/1.4 permits usable shutter speeds even in poor light situations.\n\nThis lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).
