An ultra-telephoto zoom up to 500mm producing high performance with digital or film SLR cameras.

  • Aspherical lenses and SLD glass provide correction for all types of aberration throughout the entire zoom range.
  • Rear focus system ensures fast auto focus.

The Sigma Corporation is pleased to announce the launch of the new 170-500mm F5-6.3 DG lens. This compact ultra telephoto zoom lens covers a useful range up to 500mm.

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.
