The Sigma Corporation is pleased to announce the launch of the new APO 150-500mm F5-6.3 DG OS HSM Ultra telephoto zoom lens covering a telephoto range up to 500mm
This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close with short perspective. Sigma�s original OS (Optical Stabilizer) function offers the equivalent of using a shutter speed approximately 4 stops faster. 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 minimises 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 F7-8.8 MF ultra-telephoto zoom lens or a 300-1000mm F10-12.6 MF ultra-telephoto zoom lens respectively. A removable tripod collar (TS-31) is included as a standard component.
Available April 2008
