Product Details

Leica Summilux-M 50mm f /1.4 ASPH Lens - 11891

A combination of the know-how of Leica's engineers and the latest developments in manufacturing technology has resulted in this outstanding standard lens. It delivers high-contrast images, with high-resolution detail, even at its widest aperture, and 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. The properties of this lens not only make it ideal for any photo situation demanding a handy all-rounder with the natural image angle of the 50 mm standard focal length, but also for available light situations, selective-focus shots, and even fine art photography - usually the preserve of much larger formats. Its wide-ranging versatility also makes it a top choice in assembling a Leica M lens outfit.

Leica Camera AG has unveiled a new highspeed standard lens for the Leica M System offering maximum imaging performance: the new LEICA SUMMILUX-M 50mm f/1.4 ASPH. It supersedes the predecessor lens with the same speed, which, notwithstanding a few minor modifications, had been part of our range since 1962. . The aim of this new development was to create a reference lens to push the technical boundaries of photography using standard focal lengths into new dimensions. 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, the LEICA SUMMILUX-M 50mm f/1.4 ASPH. handles every situation with ease.. It therefore delivers on its promise to be a genuine universal lens in impressive fashion. Every innovation currently available in lens technology – aspherical lenses, glass with anomalous partical dispersion, glass with a high refraction index and a floating element- have been combined to create a lens that sets the new standard in this focal length class.
