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 Canon EF 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.
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.
