Now SIGMA is introducing the 14-24mm F2.8 DG HSM | Art as the ultimate ultra-wide-angle zoom. While minimising distortion, this lens offers outstanding F2.8 brightness throughout the zoom range and delivers top-level image quality at every focal length and every shooting distance. For these reasons, it is the definitive wide-aperture ultra-wide-angle zoom lens.
Outstanding Art line image quality
Designed to team up with 50-megapixel-plus cameras and offer top-level optical performance throughout the zoom range, the 14-24mm F2.8 DG HSM | Art incorporates three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one large-diameter aspherical element. Effective distribution of these high-refractive-index glass elements further enhances the corrective effect of the FLD and SLD glass. This optical system minimises transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.
The first element in the optical system is a large-diameter aspherical lens. Optimising the power distribution of this and the other lens elements minimises distortion to 1% or lower.* As a result, points of light appear as points without streaking from the centre of the image to the edge, and the light volume is also abundant throughout the frame. In addition, simulations performed from the design stage onward have helped minimise flare and ghosting. In combination, these technologies ensure excellent ultra-wide-angle performance.

Compatible with Canon Lens Aberration Correction
The Canon mount lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera correction of peripheral illumination, chromatic aberrations, distortion and more, further enhancing image quality.
*Function not available on all Canon cameras. Further, available corrections may vary by Canon camera model.
Like SIGMA’s Sports line lenses, the 14-24mm F2.8 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.
