The Sigma 50mm f/1.4 DG HSM Art lens is a professional-level fixed focal length lens made by Sigma Corporation.[1] It was announced at CES in January 2014 and immediately became highly anticipated amid reports that Sigma was not aiming to compete against Canon or Nikon's 50mm prime lenses but rather the newly released Zeiss Otus 55/1.4, a lens costing US$4000.[2] Retail prices for the Sigma 50mm lens had not yet been announced but it was initially expected that it would sell for around US$1350.[3] However, when official pricing was announced on April 11, 2014, the retail price was even lower: US$950.[4]

Lens reviews of the Sigma 50mm f/1.4 DG HSM Art have been largely very positive, and have confirmed the expectations that it is significantly sharper than the 50mm f/1.4 prime offerings by Canon and Nikon[5] while also significantly cheaper. Chromatic aberration is minimal across the aperture range, as is distortion, and the lens is sharpest at f/5.6, after which it is marginally softer as diffraction effects become more prominent.[6]

In recent reviews it has been shown that the Sigma 50mm f/1.4 DG HSM is sharper and has smoother bokeh than the Canon 50mm F/1.2 Lens.[7]
