Product Description

The 20mm f/1.4 DG HSM Art Series Lens from Sigma is a premium lens designed for full frame cameras, but is compatible with ASP-C sensors as well. The wide 20mm focal length is perfect for an everyday carry setup. Exceptional image quality is derived from the Art Series’ use of both "F" Low Dispersion (FLD) and Special Low Dispersion (SLD) glass. With 15 elements in 11 groups, the 20mm 1.4 DG HSM is designed to reduce flare and ghosting by transmitting and realigning scattered light to the best focal point for high contrast and truer colors, as well as perfect blurred background effects (bokeh).

The barrel of the lens is constructed from a Thermally Stable Composite (TSC) that doesn’t distort or lose hardness with changes in weather. It features new and exclusive Sigma technology, such as an enhanced Hyper Sonic Motor (HSM—quick and silent autofocusing) and a new manual override (MO) switch that disables autofocus to give you total control. It is compatible with the Sigma USB dock (not included) for firmware updates and focus microadjustment. Every part of Sigma’s lenses are manufactured, assembled, and tested in Japan under an integrated production system.
