Sigma 100-300mm F/4.0 EX DG IF HSM Autofocus Lens for Nikon AF-D

The Sigma 100-300mm F/4.0 EX DG IF HSM  telephoto zoom lens provides a large constant f/4 maximum aperture at all focal lengths. The use of Apochromatic design and 4 SLD (Special Low Dispersion) glass elements give full correction of chromatic aberration and provide a high level of optical performance.

The AF drive for the Nikon mount is equipped with the silent, responsive and high speed Hyper Sonic Motor and provides fulltime manual focus override. A removable tripod mount is provided with the lens. Handholding is easy since focusing and zooming do not change its overall length.
