Closer to the action
With its high speed and unique depth of focus, the APO-Summicron-SL 90mm f/2 ASPH. is the ideal choice for portrait photographers. Its nearly silent and precise autofocus allows photographers to focus more on the creative aspects of their subject.
Like all Leica SL lenses, it is perfectly integrated with the modern SL system and built for durability in professional shooting conditions.
Constructional details of the APO-Summicron-SL 90mm F/2 ASPH.
The APO-Summicron-SL 90mm f/2 ASPH. features an optical system with 11 elements, including one aspherical surface. A high proportion of these elements is made from specially formulated glass to correct chromatic aberrations. Their anomalous partial dispersion minimizes color fringing, ensuring sharp highlights free from distortion.
AF System with Dual Syncro Drive™
The Summicron-SL lenses feature a fast, precise, and nearly silent autofocus system, thanks to a shared drive unit. Their performance is influenced by the mass of the lens elements, focusing range, and available space, requiring compact integration.
Engineered with double internal focusing, the system uses lightweight elements to create small, efficient drive systems. Powerful, robust stepping motors with Dual Syncro Drive™ enable rapid and precise focusing, meeting the demands of contrast-based autofocus.
As a result, Summicron-SL lenses excel in speed, precision, and minimal noise, making them among the best in the full-frame segment.
