Sigma’s 14-24mm F2.8 DG HSM | Art ultra-wide-angle zoom lens minimizes distortion while offering outstanding F2.8 brightness throughout the zoom range. Designed to team up with 50-megapixelplus cameras, this lens incorporates three FLD glass elements, three SLD glass elements, and three aspherical lens elements. The first element in the optical system is a large-diameter aspherical lens. Optimizing the power distribution of this and the other lens elements minimizes distortion to 1% or lower (at infinity focus) and points of light appear as points without streaking from the center of the image to the edge. 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.
