Sigma 24-35mm f/2 DG HSM Art Lens Features & Specs, Announced

Update: Already announced ! You can see pre-order option at B&H Photo Video and Adorama. Price is not available yet, shipping date will at the end of July. It will be available for Canon EF mount, Nikon F mount and Sigma mount.

Here are first full specs and features of to be announced Sigma 24-35mm f/2 DG HSM Art Lens. The Sigma 24-35mm F2 DG HSM Art is the worlds first full frame F2 zoom lens. Covering a common prime lens lineup, the 24-35mm F2 DG HSM was designed for prime performance with the versatility of a zoom lens. Premium FLD glass, with performance equal to flourite, and seven SLD glass elements allow for outstanding image quality. A large diameter aspherical lens, a complicated element to manufacture, allows for a stunning level of brightness. This complicated optical formula creates outstanding image quality throughout the focal range, and even at the widest of apertures. An updated AF algorithm makes for smooth, accurate and fast autofocusing while multi layer coating control flare and ghosting. The Sigma 24-35mm F2 DG HSM Art is another notch on Sigma’s belt for pure photographic innovation.

Features:

• 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, resulting in outstanding optical performance
• A video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens’ stability and allowing use of circular polarizing filters
• A 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-focus areas of the image
• Specifications: Lens construction containing 18 elements in 13 groups; a weight of 33.2 ounces; a diameter and length of 3.4 inches by 4.8 inches, respectively; a minimum aperture of F16; and angle of view (35mm) of 84.1° to 63.4°; minimum focusing distance of 11 inches; and a maximum magnification ratio of 1:4.4
