Sigma 50mm f/1.4 Art HSM DG

a “bright” prime lens from the Sigma Art squad, which includes entirely high-quality optics with an eye on creative types of filming. The “insides” of the model are formed by an optical scheme consisting of 13 elements in 8 groups. To minimize chromatic aberrations, special SLD elements are used here, and aspherical lenses are used to reduce reflections and glare. Also under the hood of the Sigma 50mm f/1.4 DG HSM Art is a fast ultrasonic Hyper Sonic Motor autofocus drive.

The model demonstrates excellent sharpness from open apertures and draws beautiful artistic bokeh. The minimum focus distance for it is claimed in the range of 40 cm. When focus, the elements of the optical scheme of the lens move inside the body, which means it does not change dimensions and provides the ability to install filters (77 mm) on the front lens. Fix weight is 815 grams, length — 100 mm, diameter — 85 mm. The lens is available in versions for the Canon EF, Nikon F and Sony A “running” SLR systems, as well as the “native” Sigma SA.
