Leica APO Summicron SL 35mm f/2 ASPH. Overview

A favored and versatile focal length coupled with an optically refined design, the Leica APO-Summicron-SL 35mm f/2 ASPH. is a general wide-angle prime designed for full-frame L-mount mirrorless cameras. The bright f/2 maximum aperture strikes a balance between speed and overall weight and size, offering a portable form factor along with the ability to excel in available light conditions. The apochromatic optical design uses anomalous partial dispersion glass to suppress color fringing and chromatic aberrations for high clarity and color accuracy, and five aspherical elements are also featured to reduce spherical aberrations for improved sharpness. Multi-layer coatings have also been applied to limit flare and ghosting for increased contrast when working in strong lighting conditions. Complementing the optics is a Dual Syncro Drive stepping motor, which delivers fast and quiet autofocus performance to suit both stills and video applications. Additionally, an AquaDura coating has been applied to the exposed elements and seals have been incorporated in the lens design to benefit working in harsh environmental conditions.

Wide-angle 35mm f/2 lens is designed for full-frame Leica L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 52.5mm equivalent focal length.
Bright f/2 maximum aperture benefits working in low-light conditions and also affords greater control over depth of field for working with selective focusing techniques.
Five aspherical elements are used to reduce distortion and spherical aberrations for improved sharpness and accurate rendering.
Apochromatic design employs anomalous partial dispersion glass to suppress chromatic aberrations throughout the aperture range for increased color accuracy and clarity.
Multi-layer coatings have been applied to individual elements to suppress surface reflections, flare, and ghosting for increased contrast and color fidelity.
Dual Syncro Drive stepping motor delivers quick, precise, and near-silent autofocus performance to suit both photo and video applications. This system also avails full-time manual focus override.
Water-repellent AquaDura coating has been applied to the front and rear optical surfaces to protect against moisture and other elements.
Weather-sealed design protects against dust and moisture to benefit working in inclement shooting conditions.
Leica mirrorless shooters looking for a solid, everyday wide-angle prime should look no further than the newly announced APO-Summicron-SL 35mm f/2 ASPH Lens for full-frame Leica L-mount cameras. Like other Summicron-SL lenses, the 35mm includes Dual Syncro Drive stepping motor for extremely fast and quiet focusing capabilities, making this a great option for street and event photographers. Studio shooters and manual focus fans will appreciate a new focusing ring construction that uses a ring magnet to relay focus adjustments in the lens while keeping the lens sealed against the elements and protected from impact.Matching the characteristics of other Summicron-SL lenses, this 35mm f/2 is compact, while producing images that rival faster and larger lenses of the same focal length. An apochromatic design incorporating anomalous partial dispersion glass and five aspherical elements keep images sharp with minimal distortion. Additionally, multi-layer coatings manage flare and ghosting. A minimum focusing distance of 10.63" adds the ability to get up close to subjects and an aperture range of f/2-f/22 offers allows you to keep as much or little in focus you desire. The 35mm f/2 continues the exacting quality expected of the Summicron-SL series of lenses including weather sealing and a water-repellent AquaDura coating to optical surfaces for protection against moisture.
