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. A
removable tripod socket (TS-31) is included as a standard component.
