Sigma 14-24mm f/2.8 DG HSM Art Lens for Sigma SA

An ultra-wide zoom lens with a constant f/2.8 aperture, the 14-24mm f/2.8 DG HSM Art Lens from Sigma is an outstanding option for architectural and landscape shooters with full-frame Sigma SA  cameras. A part of the esteemed Art-series of lenses, a sophisticated optical design is used that incorporates three FLD, three SLD, and three aspherical elements to help reduce chromatic aberrations and keep distortion under control. A Super Multi-Layer coating has also been applied to suppress lens flare and ghosting for accurate color fidelity and high contrast.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The lens features a rounded 9-blade diaphragm that gives a smooth look to out-of-focus areas, which stops down to f/22, and offers a minimum focus distance of 10.2". Finally, a weather-sealed brass bayonet mount helps keep water and dust away from your equipment when shooting in rugged conditions.
