The Sigma 100-300mm f/4 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.
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
It is also possible to use this lens with Sigma 1.4x EX and 2x EX APO Tele Converters to convert it to an ultra tele-zoom lens.
