The Leica 50mm f/1.4 M Aspherical Manual Focus Lens (Silver) 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. Every 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.
This 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
