Fast-Aperture Portrait-Length Prime. The Sigma 85mm f/1.4 DG DN Art’s fast f/1.4 aperture makes it ideal for shooting in difficult light, achieving shallow depth of field, and giving you ample background separation for portraiture. The rounded eleven-blade diaphragm helps produce large, pleasing bokeh. Using an APS-C sensor camera? You’ll have a focal length equivalent to 127.5mm.
Stepping Autofocus Motor. The stepping autofocus motor 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 eleven-group/fifteen-element optical design includes four high-refractive index glass elements, one aspherical element, and five Special Low-Dispersion elements to minimize chromatic aberrations, distortion, and vignetting while providing maximum sharpness, color accuracy, and clarity. Each of the elements is coated with a Super Multi-Layer coating to further combat lens flare and ghosting.
Manual Aperture Ring. This lens features a manual aperture ring that can be de-clicked with a switch on the side of the lens for video shooters looking for smooth iris transitions or used by photographers looking for an easy way to check and adjust aperture.
High-Quality Build. The Sigma 85mm’s weather-resistant construction means you can use it in adverse conditions. It also boasts a brass bayonet mount for maximum durability.
Dock Compatible. This lens is compatible with the Sigma UD-11 USB Dock, which lets you fine-tune certain lens characteristics and update firmware via the free Sigma Optimization Pro software.
