Leica Camera officially announced two new APO-Summicron-SL lenses for the SL-system: APO-Summicron-SL 75mm f/2 ASPH Lens and APO-Summicron-SL 90mm f/2 ASPH Lens. The focal lengths of the two SL-Lenses are ideal for all genres of photography and are particularly suitable for portraiture. The Leica Summilux-SL 75mm f/2 costs $4,750 while the Summilux-SL 90mm f/2 is priced at $5,150. Shipping is scheduled to start in February 2018.
About Leica Summilux-SL 75mm f/2 (via Adorama):
Street, portrait, or whatever catches your eye: Conceived as a universal lens for any situation, the APO-Summicron-SL 75 f/2 ASPH. opens up new horizons for photography in the versatile zone between standard and telephoto focal lengths. It is perfectly matched to the cutting-edge SL-System and has been designed for a long life under a heavy professional workload. In addition to this, the maximum reproduction ratio of 1:5 contributes even more to the versatility of the lens, allowing for close-up shots that pop with punchy sharpness and definition.
About Leica Summilux-SL 90mm f/2 (via Adorama):
Its high speed and the unique aesthetics of its depth of focus make this telephoto lens the first choice for portrait photographers. At the decisive moment, its almost silent and simultaneously precise autofocus gives photographers more time to concentrate fully on the creative aspects of their subject, the person in front of their camera. Like all Leica SL-Lenses, the APO-Summicron-SL 1:2/90 ASPH. is perfectly matched to the modern SL-System and is constructed for a long working life under professional shooting conditions.
NEW PRIME LENSES FOR THE LEICA SL-SYSTEM: SUPERIOR PERFORMANCE AND THE FINEST ARTS OF ENGINEERING IN COMPACT DESIGN
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 all genres of photography and are particularly suitable for portraiture. While the APO-Summicron-SL 75 mm f/2 ASPH., for example, enables natural portraits, the APO-Summicron-SL 90 mm f/2 ASPH. is a classic focal length for portraiture and creates the often desired slight compression of perspectives. Both lenses are perfectly matched to the SL-System and – just like all currently available and future SL-Lenses – have been designed and constructed for a long service life in professional use.
All glass elements in an optical imaging system – for example lenses – refract light in certain colours to a different extent. This leads to the effect that not all rays of light from a multi-coloured subject are focused at a single imaging point – the result of this is chromatic aberration. In order to reduce this chromatic aberration to a hardly perceptible minimum, both new Summicron-SL lenses are apochromatic – in short: APO – corrected. For this, most of the eleven elements of the optical system – one of which is an aspherical – feature anomalous partial dispersion and are manufactured from sensitive and specially formulated, high-quality glass types.
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. New, extremely precise manufacturing methods and measuring technologies have been developed especially for the production of these lenses. The results of this are reflected not only in the more compact dimensions and considerably lower weight of the lenses, but also in their excellent imaging performance. In addition, these lenses feature a new, faster autofocus system and a considerably shorter close focusing limit.
As both Summicron-SL primes deliver extremely high imaging performance at their largest aperture, the lenses are also ideal for photography in difficult lighting conditions. The Leica promise of ‘maximum aperture is a usable aperture’ also applies to the new SL-Lenses – stopping down is exclusively a creative imaging tool, and is not necessary for achieving better imaging performance.
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.
The autofocus drive of all SL-Summicron lenses employs extremely powerful and robust stepping motors with DSD® (Dual Syncro Drive™). Thanks to these, the entire focusing throw can be travelled completely in only around 250 milliseconds.
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.
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.
