The Sigma APO 800mm F5.6 EX DG HSM affords you some of the most extreme zoom power you can find in a lens. The APO 800mm F5.6 EX DG HSM is compatible with tele converters. This means you have the option to increase the focal length of the lens to 1600mm. That is more than enough for the majority of sports and wildlife subjects.
Sigma have incorporated a drop in filter holder in the back of the lens that can accept a circular polarising filter. The filter is supplied with the lens. It also has a built in tripod socket to help with balance.
