Description: This compact ultra telephoto zoom lens covers a range up to 500mm and optimized for digital SLR cameras. The new multi-layer lens coating and lens design reduces flare and ghosting. This lens uses one aspherical lens and three SLD (Special Low Dispersion) glass elements for excellent correction all types of aberration, resulting in better picture quality on both film and digital SLRs.
