Wide-Angle Zoom. The Sigma 14-24mm f/2.8 DG DN Art’s combination of wide-angle focal range and fast f/2.8 aperture makes it great for shooting in available light, and particularly well-suited to astrophotography. The rounded eleven-blade diaphragm helps produce large, pleasing bokeh. Using a APS-C sensor camera? You’ll have a focal length range equivalent to 21-36mm.

Hyper Sonic Autofocus Motor. The Hyper Sonic Motor system provides fast, smooth, and nearly silent autofocus operation for stills and video alike. You can just rotate the focus ring at any point for manual-focus override. A built-in Autofocus-Lock button can be assigned additional functions, giving you more options and capabilities.

Advanced Optics. This lens’s thirteen-group/eighteen-element optical design includes three aspherical elements and five Special Low-Dispersion elements to minimize chromatic aberrations, distortion, and vignetting while providing maximum sharpness, color accuracy, and clarity. All of the lens elements have a combination Super Multi-Layer Coating and a Nano Porous Coating to further combat flare and ghosting.

High-Quality Build. The Sigma 14-24mm’s Thermally Stable Composite build is dust- and splash-resistant so that you can use it in adverse conditions. It also boasts a brass bayonet mount for maximum durability.
