Used Sigma 20mm f/1.4 DG HSM ART for Sony E - Excellent

Overview

The Sigma 20mm f/1.4 DG HSM Art Lens allows you to capture wide-angle shots of vast landscapes and large structures. Designed for Sony E-mount cameras, the lens's optical design consists of 15 elements in 11 groups. Two FLD and four SLD elements, as well as two aspherical lenses, correct chromatic and spherical aberrations. And, the super multi-layer coating reduces ghosting and lens flare to provide clarity and high image saturation. The Hyper Sonic Motor AF system works silently to acquire focus on objects from a close distance of 10.9 inches. Further, with the manual AF override, you may adjust the autofocus setting by turning the focus ring. Also, the rounded 9-blade diaphragm, along with a fast aperture of f/1.4, creates a shallow depth of field with circular bokeh effect. This Sigma lens is made of a Thermally Stable Composite material, while the brass bayonet mount features a dust- and splash-proof rubber sealing.
