Leica Unveils 75mm f/2 and 90mm f/2 Lenses for the SL System
Leica has announced two new prime lenses for its Leica SL-System: the APO-Summicron-SL 75mm f/2 ASPH and APO-Summicron SL 90mm f/2 ASPH.
As part of a new line of “high-performance Summicron-SL lenses,” the two lenses have been designed and constructed in Germany using “exceptional materials” to allow for a “long work life.”
Both lenses have fast and silent autofocus systems, with a “considerably” close focus limit: 0.50 meters (19.69 inches) for the 75mm, and 0.60 meters (23.62 inches) for the 90mm. The entire focus range can be traveled in an impressive 250 milliseconds. That’s thanks to the “extremely powerful and robust” stepping motors with DSD (Dual Syncro Drive).
Leica says that it paid meticulous attention to the prevention of stray light and reflections during the construction of the lenses, and together with high-quality coatings to each lens surface has meant for unavoidable reflections to be reduced to a minimum.
The lenses are also Apochromatic (APO), meaning they are corrected to allow photographers to capture photos in high contrast situations with minimal chromatic aberration. They’re constructed of 11 elements (in 9 groups), one of which is aspherical, and all elements feature anomalous partial dispersion.
Both lenses have 9 diaphragm blades, are sealed, and have a filter thread of 67mm. The 75mm lens weighs 720 grams, and the 90mm weighs 700 grams.
The Leica 75mm f/2 and 90mm f/2 lenses will be available in February 2018, costing $4,750 and $5,150 respectively. Leica will also be launching a 35mm f/2 and 50mm f/2 lens to the join this new series in the second half of 2018.
