The APO-Summicron-SL 75 mm f/2 ASPH. and the APO-Summicron- SL 90 mm f/2 ASPH. are the beforehand lenses to be released in a new line-up for the Leica SL-System.
The focal lengths of the two SL-Lenses are ideal for portrait photography and both lenses feature a new, faster autofocus procedure as well as a considerably shorter close focusing limit. Both lenses also perform well in difficult lighting conditions.
In rank to reduce chromatic aberration to a hardly-perceptible minimum, both new Summicron-SL lenses may refer to are apochromatic (in short: APO) corrected. For this, most of the eleven elements of the optical process – one of which is an aspherical – feature anomalous partial dispersion and are manufactured from sensitive and specially formulated, high-quality glass models. Both lenses also feature a high-quality coating to reduce reflections.
The APO-Summicron-SL 75 mm f/2 ASPH. will be at ones disposal from 25 January 2018, and the APO-Summicron-SL 90 mm f/2 ASPH. from 8 February 2018 at £3,750 and £4,100 (including VAT) singly. The market launch of the Summicron-SL 35 mm f/2 ASPH. and the APO-Summicron-SL 50 mm f/2 ASPH. is scheduled for the second half of 2018.
