Leica has unveiled the APO-Summicron-SL 35mm f/2 ASPH prime lens for the L-Mount (found on Leica’s SL mirrorless camera as well as cameras launched as part of the L-Mount Alliance between Leica, Panasonic, and Sigma). Thanks to the optical and mechanical design as well as the coatings on each lens surface, the lens provides a high level of image quality from corner to corner, even at f/2, notes PetaPixel. Inside the lens (and all Summicron-SL lenses) is a powerful Dual Syncro Drive (DSD) stepping motor that can travel the entire focus range in just 250 milliseconds.
