Leica Summilux-SL 50 mm f1.4 ASPH

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 depth of field 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.


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.


Refined optical systems guarantee the exceptional imaging quality of the Leica SL-Lenses. Aspherical elements are employed for the correction of monochromatic aberrations. Specially formulated glass types eliminate chromatic aberrations. In the design of the lenses, particular care has been taken to ensure homogeneous imaging performance at all focal lengths and settings. This allows the choice of the ideal aperture for the creative effect you have in mind in every situation. As Leica SL-Lenses already achieve extremely high contrast values at maximum aperture, they are particularly suitable for the creative use of planes of sharpness and unsharpness and the distinct isolation of subject details. In addition, sophisticated coating on all lens surfaces effectively minimizes reflections, stray light, and flare.


The shorter register due to the omission of the mirror and its related components is exploited by newly developed optical and mechatronic constructions. These allow lenses used with the camera to deliver even better performance in all disciplines. For the preservation of consistent imaging quality at closer focusing distances, the SL-Lenses feature floating elements that are positioned separately with their own motors. For this, only particularly light focusing elements that fulfill the demands of a fast, responsive, and almost-silent autofocus system are employed in the lenses. Thanks to their encapsulated construction and seals impervious to water and dust, SL-Lenses are ideally protected against potentially damaging environmental influences. In addition, Leica AquaDura® coating provides effective protection of the exposed surfaces of lenses against dirt and scratching.
