Leica has announced its new APO-Summicron-SL 35mm f2 ASPH lens, an L-mount lens designed to be used with Leica’s SL mirrorless cameras as well as Panasonic and Sigma cameras as part of the L-Mount Alliance.

“Innovative production methods and new technologies paired with impeccable imaging performance make the latest lens of the Summicron-SL series the new benchmark for the classic reportage focal length,” Leica says.

The company says it paid particularly close attention to preventing stray light and reflections in the lens. 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 f2.

This lens features 13 elements in 11 groups, including five aspherical elements. Also feature a hydrophobic Aquadura coating on the exterior lens surfaces. The body of the lens is sealed against both dust and moisture.

“The lens can be used without a second thought to perform in almost any weather conditions,” Leica says. “By design, the Leica SL-System and its lenses instill confidence in the user that they will always be able to get the shot regardless of extreme environmental elements.”

As with other lenses in Leica’s Summicron-SL collection, the 35mm f2 ASPH lens features a Dual Syncro Drive (DSD) steeping motor for fast autofocus. Leica says the lens ‘completely travels the entire focus range in just 250 milliseconds.’

The lens measures 102mm / 4.02in long and 73mm / 2.87in in diameter and weighs in at 720g / 25.4oz.

The APO-Summicron-SL 35mm f2 ASPH. lens will go on sale in mid-April for $4,595 at Leica Stores, Boutiques and authorized retailers.
