- Powerful high-performance lens
- Sealed against dust and splashes of water
- Fast and quiet focusing
- Creative use of sharpness and blurring
The Leica 50mm f/1.4 Summilux-SL ASPH Lens is the first SL prime lens in the Leica portfolio. This autofocus lens delivers outstanding optical performance and sets the next generation benchmark from the leaders in optical technology. Its large maximum aperture makes the high-performance lens the ideal partner in situations with challenging lighting conditions and enables the use of shallow depth of focus as a creative tool.
Particularly when shooting at maximum aperture, the combination of its resolving power and soft bokeh in unsharp areas clearly isolates subjects from their surroundings. Thanks to uniform contrast rendition throughout the focusing range, this applies at all distance settings. With its internal focusing design, the overall length of the lens remains unchanged when focusing. This lens does not compromise on any aspect of optical performance.
The Leica Summilux-SL 50mm f/1.4 ASPH optical design contains a total of 11 elements, of which two are aspherical elements and four are made from glasses with anomalous partial dispersion for the correction of chromatic aberrations.
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 Summilux-SL 50 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.
L-MOUNT - A new era of creative freedom
The L-Mount marks the start of a new era of lens compatibility without compromise. Never before has one lens mount standard allowed for an almost limitless array of options in combining different interchangeable lenses with cameras featuring different sensor formats.
With the alliance between Leica Camera, Panasonic and Sigma, a combined 250 years of experience in the field of lens and camera construction will be consolidated in one platform. For the photographer, this opens up the chance to compile endless variations of camera-lens combinations from the extensive product portfolios of all three manufacturers, and so continually find the best solution for any photographic situation.
