Sigma 170-500mm f/5-6.3 APO DG announced

Sigma 170-500mm f/5-6.3 APO DG

The new multi-layer lens coating and lens design reduces flare and ghosting, and creates an optimum color balance resulting in better picture quality through the entire zoom range on both film and digital SLRs.

This lens uses one aspherical lens and three SLD (Special Low Dispersion) glass elements for excellent correction of chromatic aberration, making high-quality images a reality throughout the entire zoom range.

Since the front of the lens does not rotate during focusing, a circular polarizing filter can easily be attached and used. A lens hood and removable tripod collar are included as standard components.
