Sigma 300-800mm f5.6 EX DG HSM Lens - Canon Fit

This digitally optimised lens covers the ultra-telephoto range up to 800mm and has a fast maximum aperture. Its new lens coating reduces any flare and ghosting, a common problem with digital cameras and also creates an optimum colour balance.

The lens incorporates two ELD (Extraordinary Low Dispersion) glass elements for effective compensation of chromatic aberrations and ensure sharp, quality images with high contrast.

The addition of an HSM (Hyper Sonic Motor) makes quick, silent AF function a reality. The lens is also capable of full-time manual focus.

Focusing and zooming do not change the lens' actual length, ensuring its easy of use either handheld or on a tripod.

A 46mm filter can be inserted near the rear of the lens, and the included circular polarizing filter can be used in situ.

A heavy duty tripod bush is included as astandard component for use with tripods and monopods. Multiple threaded holes allow accurate balancing of lens and camera body. This is also designed as an easy grip when carrying the lens.

When this lens is used with the optional 1.4x EX or 2x EX Apo Tele Converters, it becomes a 420-1120mmF8 MF lens or a 600-1600mm F11 MF lens respectively.
