APO-SUMMICRON-SL 75 f/2 ASPH., black anodized finish

APO-Summicron-SL 75mm f/2 ASPH. from Leica is an optically refined short tele prime designed for full-frame L-mount mirrorless cameras. Complementing the slightly long, versatile focal length is a bright f/2 maximum aperture that affords great control over depth of field and also suits working in less-than-ideal lighting conditions. One aspherical element is used to reduce distortion and spherical aberrations for improved sharpness and accurate rendering. The apochromatic optical design uses anomalous partial dispersion glass to suppress color fringing and chromatic aberrations for high clarity and color accuracy, and one aspherical element is 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. Floating elements system and an internal focusing design maintain consistent image quality throughout the focusing range, from 1.6' to infinity. Complementing the optical assets is a Dual Syncro Drive stepping motor, which delivers fast and quiet autofocus performance, and a floating elements system maintains consistent imaging quality throughout the focusing range. Additionally, an AquaDura coating has been applied to the exposed elements as Weather-sealed design protects against dust and moisture to benefit working in inclement shooting conditions.
