The Sigma 120-300mm f/2.8 EX APO DG IF HSM telephoto zoom lens provides a large constant f/2.8 maximum aperture at all focal lengths. In essence, it transforms a large-aperture 300mm f/2.8 lens into a zoom lens that allows you to determine the picture composition without having to change the vantage point.
The use of Apochromatic design and SLD glass elements, an AF drive equipped with the silent, responsive and high speed Hyper Sonic Motor, and Internal Focusing all ensure optimal quality and usability. The DG design makes it fully optimized for use with digital SLR cameras.
