Leica 50mm f/1.4 ASPH Summilux-SL Lens

The new reference lens of this focal length

The Leica Summilux-SL 1:1,4/50 mm ASPH. is designed to deliver maximum optical performance and establishes new benchmark standards in terms of sharpness. Thanks to internal focusing, the overall length of the lens remains unchanged when focusing.

The Leica Summilux-SL 50 mm f/1.4 ASPH. is the first prime lens in the SL-System portfolio and the new reference lens in its class. This extremely fast, high-performance standard lens is ideal for capturing subjects in natural lighting and offers the advantages of shallow depth of focus as a creative tool. Thanks to the outstanding precision of its autofocus, it allows you to concentrate fully on your subject and the composition of a perfect picture. The imaging performance of the lens fulfills even the most stringent standards. Particularly at maximum aperture, its high resolving power and the pleasingly soft bokeh in out of focus areas isolate the subject clearly from its surroundings. Thanks to the consistent contrast rendition throughout the focusing range, this applies equally for all distance settings.

Construction details

A special feature of its construction is the motorized focusing system. In contrast to manually focused prime lenses, where the length generally varies when focusing, the Leica Summilux-SL 50 mm f/1.4 ASPH. has internal focusing*. To ensure high imaging performance throughout the entire focusing range, the focusing group is elaborately constructed with an aspherical element, yet remains light enough to guarantee fast automatic focusing.Its optical design contains a total of 11 elements. Of these, two are aspherical elements and a further four are made from glasses with anomalous partial dispersion for the correction of chromatic aberrations. This complex optical construction reduces all monochromatic and chromatic aberrations to a hardly perceptible minimum. Advanced multilayer coating on all lens surfaces, the optimum design of the lens tubes, and the rectangular lens hood provided with the lens significantly reduce reflections and stray light.

Black-chrome finish model

The black-chrome finish design version of the Summilux-M 50 mm f/1.4 ASPH. is exceptional and exclusive. The matte black look model is made of solid brass. The traditional design is inspired by its predecessor from 1959 and reflects its typical features, such as the scalloped focusing ring and a finely knurled aperture ring.  In addition, the feet scale design is in red. Furthermore, a round metal lens hood and a metal lens cap are also included in the package.
