The Sigma 14-24mm F2.8 DG HSM Art lens is the ideal ultra-wide-angle zoom lens for the most demanding photographers. With a constant F2.8 aperture throughout the entire zoom range, it’s designed for 50-megapixel plus cameras for outstanding high-resolution image quality. An updated Hyper Sonic Motor (HSM) provides fast and accurate autofocus. 3 FLD and 3 SLD glass elements; 3 aspherical lens elements; and 1 large-diameter aspherical element minimize chromatic aberration resulting in extremely sharp images.
Outdoor shooters will appreciate the dust- and splash-proof construction with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
