The Sigma APO 150-500mm F5-6.3 DG OS HSM lens is a super-telephoto lens produced by Sigma Corporation. It contains three SLD (Special Low Dispersion) glass elements to provide correction for chromatic aberration. It is aimed toward advanced consumer level photographers, and is available in Nikon, Canon, Pentax and Sigma camera mounts.
The optical construction consists of 21 lens elements divided into 15 groups. The 9-bladed diaphragm begins at f/5 when shooting wide open, progressing towards f/6.3 at 500mm. As expected with similar long telephoto zoom lenses, optical quality drops off at the extremes of the telephoto range.
Autofocus is achieved using a moderately fast hypersonic motor for quiet operation. Additionally, all focus elements are internal so in operation the front element does not rotate or extend during focusing, which is useful when a polarizing filter is employed.
