SIGMA 120-300/2.8 DG OS APO HSM SPORT LENS FOR CANON (CALL IN SOUTH AFRICA

The Sigma APO 120-300mm f2.8 EX DG HSM Lens for Canon Digital SLR Cameras features a large aperture of f2.8 at the 300 millimeter focal length and is optimized for used with digital SLR cameras. This lens transforms a large-aperture f2.8 300 millimeter lens into a zoom lens that allows you to determine the picture composition you want without having to change your vantage point. It has two SLD (Special Low Dispersion) glass elements in front group and another SLD element in the rear group for excellent correction of chromatic aberration. The latest in multi-layer lens coating technology and lens design reduce flare and ghosting, which is a common problem with digital cameras, and it also creates an optimum color balance through the entire zoom range. The lens' AF drive is equipped with a silent, responsive and high speed Hyper Sonic Motor (HSM), which also provides full-time manual focus function. Since focusing and zooming do not change its overall length, this lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and used.
