Sigma lenses : 170-500mm f5-6.3 APO DG

Sigma 170-500mm f5-6.3 APO DG

This compact apochromatic ultra-telephoto zoom lens reduces distortion aberration to less than 1% by using aspherical lenses, and colour aberration in the secondary spectrum is compensated for using three pieces of Special Low Dispersion Glass (SLD). the five group zoom and rear focus systems ensure smooth automatic focusing, stability, and ease of use. A removable tripod collar is included as a standard component.
