Designed as a reference lens for the M-mount system, the black Summilux-M 50mm f/1.4 ASPH. from Leica is a versatile normal-length prime characterized by its bright maximum aperture and sophisticated optical design. Comprising eight elements in five groups, the lens features one aspherical element to reduce spherical aberrations and both anomalous partial dispersion and high refractive index glasses are used to control color fringing and chromatic aberrations for improved clarity. Additionally, a floating elements system is used to maintain consistent image quality throughout the focusing range, down to 2.3'. Additionally, the lens features a built-in extendable lens hood and is threaded to accept 46mm screw-in filters.
