The Canon EF-mount 50mm f/1.4 DG HSM from Sigma is a fast normal-length prime ideal for capturing sharp images with accurate colour and smooth bokeh. As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Optically, three Special Low Dispersion glass elements and one molded glass aspherical element work to reduce chromatic aberrations, while the lens' large diameter and floating system help to correct vignetting. A Super Multi Coating has been applied to lens elements to reduce flare and ghosting for improved contrast and accurate colour. This is complimented by a bright f/1.4 maximum aperture and a rounded nine-blade diaphragm that make it a great choice for working with shallow depth of field and in low light situations.

The lens uses an integrated HSM (Hyper Sonic Motor) for quick, smooth, and quiet autofocus performance with full-time manual focus override. Alongside this, the lens is constructed using a Thermally Stable Composite material for durability, and a brass bayonet mount also offers rigidity and mounting precision. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
