Finally Sigma announced the world’s first full frame F2 zoom lens namely Sigma 24-35mm f/2 DG HSM Art Lens. Sigma designed it for the prime performance with the capability of zoom lens for creative and artistic applications.
Sigma used one FLD and seven SLD glass elements within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity, and contrast. The lens has also full control over depth-of-field with an aperture range from f/2 to 16, and when used on APS-C camera bodies it has an equivalent focal length of 38.4-56.
It has also a rounded nine-blade diaphragm which helps to produce an attractive out-of-focus quality.
The Sigma 24-35mm f/2 DG HSM Art Lens is sported with a silent Hyper Sonic AF Motor which helps to optimize autofocus algorithm for fast and accurate tracking.
The body of the 24-35mm is constructed of a Thermally Stable Composite material which performs well in all conditions. It’s Super Multi-Layer Coating reduce the flare and ghosting and hence results sharp and high-contrast images and it can also focus at the closeness of 11”.
The optimized AF algorithm helps to produce smooth and fast autofocusing performance with accuracy.
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
