Sigma 50mm f/1.4 DG HSM Art Lens for Sony E

The Sigma 50mm f/1.4 DG HSM Lens for Sony E-mount is a fast and versatile prime lens designed to deliver exceptional optical performance. It incorporates three Special Low Dispersion glass elements and one molded glass aspherical element to minimize sagittal coma flare and chromatic aberrations, resulting in high image sharpness and clarity. The lens’s large diameter and floating system also correct for vignetting, ensuring maintained peripheral brightness. A Super Multi Coating is applied to reduce flare and ghosting, enhancing contrast and color fidelity. With its bright f/1.4 maximum aperture and rounded nine-blade diaphragm, it is an ideal lens for portraiture, offering selective focus and smooth bokeh.

The lens features a Hyper Sonic Motor (HSM) that provides quick, smooth, and quiet autofocus performance with full-time manual focus override. The lens’s physical design incorporates Thermally Stable Composite (TSC) material for durability in various environments, while the brass bayonet mount ensures rigidity and precise mounting.
