Sigma 24-35mm f/2 DG HSM Art Lens for NIKON

Features:

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.

• Large-diameter, aspherical lens elements, which require advanced technologies to produce, one "F" Low Dispersion (FLD) glass, and seven Special Low Dispersion(SLD) glass elements with two aspherical lenses. The advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration and field curvature
• Video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens' stability and allowing use of circular polarizing filters
• Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function. Smoother AF is achieved when the this AF algorithm is optimized
• Full-time MF by rotating the focus ring of the lens while auto focusing
• A nine-blade, rounded diaphragm creates an attractive blur to the out-of-focusareas of the image
