Sigma 120-300mm f/2.8 EX APO DG IF HSM Autofocus Lens For Nikon AF DSLRs

The Sigma 120-300mm f/2.8 EX APO DG IF HSM is a fast, high-performance telephoto zoom lens designed for Nikon F-mount SLR and DSLR cameras. Offering a constant f/2.8 maximum aperture throughout its entire focal range, it combines the subject isolation and light-gathering capabilities of a prime telephoto lens with the framing flexibility of a zoom. Engineered with an Apochromatic (APO) optical design featuring four Special Low Dispersion (SLD) glass elements, internal focusing, and internal zooming, this lens maintains its physical length during operation. Driven by a Hyper Sonic Motor (HSM) for quick, quiet autofocusing, it is an ideal choice for sports, action, wildlife, and event photography.
