Leica Summilux-M 50mm 1,4 Asph.

The Summilux-M 50mm f/1.4 ASPH. delivers high-contrast images with high-resolution detail – even at its widest aperture, or down to its minimum focusing distance. This is made possible by a number of factors including the use of a floating element, special glass types with unique refraction properties, and elements with aspherical surfaces.
