 Sigma 800mm ultra telephoto lens
The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. The Hyper Sonic Motor (HSM) ensures an ultra-quiet, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon mount lenses. A 46mm filter can be inserted near the rear of the lens, and a circular polarising filter can be used in situ. By adding a 1.4x EX APO teleconverter (optional extra), you can use this lens as a 1120mm F8 MF ultra-telephoto lens or as a 1600mm F11 MF ultra-telephoto lens with a 2.0x EX APO teleconverter.
