The APO-Summicron-SL 75 mm f/2 ASPH. and the APO-Summicron-SL 90 mm f/2 ASPH. are the first two of a new line of high-performance lenses for the Leica SL-System. The focal lengths of the two SL-Lenses are ideal for portraiture.
In the construction of the APO-Summicron-SL lenses, particular attention has been paid to the prevention of stray light and reflections. Together with an optimisation of the optical and mechanical design, the application of high-quality coating to lens surfaces reduces unavoidable reflections to an absolute minimum. In order to reduce the chromatic aberration to a hardly perceptible minimum, both new Summicron-SL lenses are apochromatic corrected.
Both the construction and the design of the cutting-edge Summicron-SL line represent the next step forward in the development of lenses for the Leica SL-System. The results of this are reflected not only in the more compact dimensions and considerably lower weight of the lenses (ca. 700 g), but also in their excellent imaging performance. In addition, these lenses feature a new, faster autofocus system and a considerably shorter close focusing limit.
The APO-Summicron-SL 75 mm f/2 ASPH. will be available from 25 January 2018, and the APO-Summicron-SL 90 mm f/2 ASPH. from 8 February 2018.
