Amazon.com Product Description:
The Sigma APO 170-500mm f5-6.3 DG Lens for Minolta Digital SLR Cameras is an ultra-telephoto zoom that offers high performance with both digital or film SLR cameras. Optimized for digital SLR cameras, it features a new multi-layer lens coating and a lens design that reduces flare and ghosting. This lens uses one aspherical lens and three SLD (Special Low Dispersion) glass elements for excellent correction of all types of aberration, resulting in better picture quality on both film and digital SLRs.

The new multi-layer lens coating and lens design also creates optimum color balance through the entire zoom range. Ideal for sports, nature, wildlife, and landscape photography, this lens features a five-group zoom and rear focus system that ensures high performance stability and ease of use. Since the front of the lens does not rotate, a circular polarizing filter can be easily attached and usedd. A zoom hood is supplied with the lens to prevent flare and ghosting as well as extraneous light that is harmful to image quality. A removable tripod collar is also included as a standard component.
