Designed to capture edge-to-edge high resolution imagery throughout the entire zoom range, the Sigma 24-70mm f/2.8 DG DN Art lens is compatible with the latest mirrorless camera bodies. This large-aperture standard zoom lens delivers exquisite detail and accurate color composition, thanks to eight low-dispersion elements and three aspherical elements in the body of the lens. Proprietary coatings keep images crisp and distortion-free, and the autofocus is compatible with eye-detection technology, which is used frequently in mirrorless camera systems. True-to-life color One “F” Low-Dispersion (FLD) and two Special Low Dispersion (SLD) elements in the Sigma 24-70mm f/2.8 DG DN Art lens work together to help minimize chromatic aberrations and color fringing, increasing color accuracy. Three aspherical elements reduce distortion, improving overall image clarity. With a minimum focusing distance of just over 7” and a maximum magnification of 1:2.9 at the wide-angle end, you'll achieve truly remarkable detail. Defined, clear images In addition to a Super Multi-Layer coating, lens surfaces in the Sigma 24-70mm f/2.8 DG DN Art lens are treated with Sigma’s proprietary Nano Porous Coating (NPC). This porous silica layer reduces the refractive index better than other antireflection coatings currently in use, resulting in crisp image quality without ghosting or flaring. Increased control Depending on the camera body used with the Sigma 24-70mm f/2.8 DG DN Art lens, a programmable Auto Focus Lock (AFL) button allows you to assign various functions, helping you to streamline your shoot. A zoom lock mechanism prevents the lens barrel from extending unexpectedly, and dust- and splash-proof construction help keep your lens safe in a wide range of conditions.
