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 characterised 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 colour fringing for improved clarity and colour accuracy. A Super Multi-Layer Coating is also featured, and helps to suppress ghosting and flare when working in strong lighting conditions.
