Prime IQ with Z00m Versatility
The Sigma 50-100mm f/1.8 DC HSM Art Lens pares an all around telephoto focal length range with a fast constant maximum aperture, designed for Canon EF, Nikon F (DX), and Sigma SA Bayonet DSLRs, and delivers a 75-150mm (35mm) equivalent focal length expanse. The bright constant maximum aperture provides consistent low-light performance all through the entire zoom range and also allows enhanced control over focus adjustment for shallow depth of field and discerning focus applications. Complementing the all-around telephoto range is a state-of-the-art optical design that includes three F Low Dispersion elements, a single Special Low Dispersion element, and a single high-refractive index, high-dispersion glass element. This low dispersion design combination works to noticeably diminish chromatic aberrations and color fringing all through the entire zoom range, along with delivering a high degree of contrast and clarity. In addition, a Super Multi-Layer Coating has been added to lens elements to cut down on lens flare and ghosting to take advantage of working in strong lighting situations. An unprecedented combination of focal length and speed, the Sigma 50-100mm f/1.8 lens provides an array of best-liked telephoto perspectives in
flexible combination with a maximum aperture.
Refined physical construction along with internal focus and zoom mechanisms complements the imaging capabilities and limits the overall length of the lens during shooting. A Hyper Sonic AF motor delivers quick focusing speeds and quiet operation as well as providing the ability to manually override focus any time during shooting for enhanced control. Also ideal quick shooting applications, the nine-blade diaphragm made up of fluorine-coated polycarbonate, together with a carbon feather film for exceedingly smooth, controlled performance when shooting at high shooting speeds. A tripod collar is integrated into the layout, for greater stability when working with a tripod or monopod.
