The Leica Summilux-SL 1:1.4/50 mm ASPH. is designed for maximum optical performance and achieves new best values in terms of sharpness. Thanks to the fast internal focusing, the length of the Lens is not changed when focusing.
The Leica Summilux-SL 1:1.4/50 mm ASPH. is the first fixed focal length Lens in the SL system and the
new reference in its class. The fast high-performance lens is ideal for shooting situations under natural lighting conditions and offers shallow depth of field as a means of image composition. Thanks to the very precise autofocus, you can concentrate solely on the subject and the perfect image composition, even under difficult conditions. The optical imaging performance of the Lens meets the highest standards. Especially with an open aperture, the high resolution in combination with the soft bokeh in the blur allows the subject to be clearly separated from its surroundings. This applies to all distance settings thanks to the uniform contrast rendition across the entire setting range.
Construction in detail
The special feature of the construction lies in the design of the motor-driven focusing. In contrast to manually focused fixed focal lengths, whose length usually varies when focusing, the Leica Summilux-SL 1:1.4/50 mm ASPH. has internal focusing. In favor of a consistently high image quality over the entire focusing range, this group is elaborately designed with an aspherical lens, yet light enough to ensure fast autofocus. The optical design features a total of eleven lenses, including two aspherical lenses and four lenses made of glasses with anomalous partial dispersion to correct chromatic aberrations. This complex optical design reduces all monochromatic aberrations as well as chromatic aberrations to a barely perceptible level. Elaborate coatings on all lens surfaces, an optimum design of lens mounts and the rectangular lens hood supplied significantly reduce reflections and stray light.
