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.
