Sigma 800mm f5.6 EX DG HSM Lens - Canon Fit

The Sigma 800mm ultra telephone lens has been digitally optimised  with a new multi-layer coating technology that lowes bothe ghosting and flare. This also ensures an accurate colour balance and high definition results.

Incorporating two extraordinary low dispersion glass elements to reduce chromatic aberration to a minimum and ensure sharp, quality images. The internal focus system ensures the overall length of the lens does not change during focusing, making sure of easy handling.

The Hyper Sonic Motor ensures an ultra-quiet, high speed AF function as well as full-time manual focusing capability for mount lenses.

A 46mm filter can be inserted near the end of the lens, and a circular polarising filter could also 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.
