Sigma 24-35mm f/2 DG HSM ART Lens for Nikon F

The Sigma new 24-35mm lens incorporates the latest Sigma technology, including an optimized autofocus (AF) algorithm for smooth, fast, and accurate focusing, as well as manual focus (MF) override functionality. As with many Sigma Global Vision lenses, Thermally Stable Composite (TSC) compound material is used, which has a high affinity to metal parts, consistently performs well at extreme temperatures, and reduces the size and weight of the lens. In addition, its Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high-contrast images, even in backlit conditions. It's ideal for close-up shooting, portraits and deep-focus landscape photography.
