This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows
photographers to bring the subject close and short perspective. Sigma's original
OS (Optical Stabilizer) function offers the use of shutter speeds approximately
4 stops slower. It is ideal for sports, wildlife and landscape photography with
handheld shooting. Three SLD (Special Low Dispersion) glass elements provide excellent
correction for chromatic aberration. This lens is equipped with a rear focus system
that minimizes fluctuation of aberration caused by focusing. The super multi-layer
lens coating reduces flare and ghosting. High image quality is assured throughout
the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures
a quiet and high-speed AF as well as full-time manual focusing capability. The
addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce
a 210-700mm F7-9 MF ultra-telephoto zoom lens or a 300-1000mm F10-13 MF ultra-telephoto
zoom lens respectively.
