EA, Prized for event, portraiture, and sports shooting, the Nikon F-mount Sigma 70-200mm f/2.8 DG OS HSM Sports Lens is a flexible telephoto zoom characterized by its bright and sophisticated design. The fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects. In regard to the optical layout, an impressive 10 low dispersion elements are used to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. A Super Multi-Layer Coating is also featured, and helps to suppress ghosting and flare when working in strong lighting conditions.
Complementing the optics is an Intelligent OS system, which minimizes the appearance of camera shake for sharper results when shooting handheld. A Hyper Sonic Motor is also used to provide quick and quiet autofocus performance along with full-time manual focus override. The physical design of the lens also incorporates several seals to guard against dust and moisture, and a water- and oil-repellent coating has been applied to the exposed elements to prevent moisture, fingerprints, or smudges from sticking to the surface. Additionally, a fixed rotating tripod collar is featured, and has a removable Arca-type compatible foot for wide compatibility with different tripod or monopod heads.
