Designed as a reference lens for the M-mount system, the silver 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.

This ‘Made in Portugal’ lens features the same stringent design and construction tolerances and pristine quality as Leica lenses made in Germany, but is available for a lower cost to USA customers.

Versatile normal-length prime lens is characterized by a bright, fast f/1.4 maximum aperture to control depth of field for selective focus techniques, as well as to benefit working in low-light conditions.

One aspherical element is incorporated within the optical design, along with anomalous partial dispersion and high refractive index glass elements, to control aberrations and distortions at all aperture and focus positions.

A rear floating element is employed to maintain consistent performance throughout the focusing range, even at the minimum focusing distance of 2.3′.
