Leica 50mm F/1.4 Summilux-M Aspherical Black 6 Bit (Built-In Hood) M Mount Lens {46} Description


Leica Camera AG's new highspeed standard lens for the Leica M System offers 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 the 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 delivers on a promise to be a genuinely universal lens.  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.

Originally introduced in 2004 this Summilux-M 50mm f/1.4 ASPH has been very successful and developed a well earned reputation as one of the best lenses around.  The same optics are also available in a special "Black-chrome finish" model 11688 version with styling harkening back to vintage Leica lenses which was introduced in 2015.  The 11688 tends to be more expensive and lack the convenient built-in lens hood of this 11891.

The 50mm f/1.4 Summilux-M Aspherical is an especially solid general purpose lens choice for any Leica M owner.
