Canon EF 100-400mm f/4.5-5.6 IS USM

The EF 100-400mm f/4.5-5.6L IS USM is Canon's fourth Image Stabilizer lens. It is a high-performance L-series telephoto zoom lens
offering sophisticated features and high image quality which is to succeed the existing EF 100-300mm f/5.6L lens. Besides having an
Image Stabilizer, this new lens also features enhancements such as ring USM for silent AF, rear focusing, a longer focal length
range, and fluorite and Super UD elements which correct secondary chromatic aberrations for high image quality. It is the first EF
zoom lens to have both rear focusing and a floating system to obtain high image quality at all focal lengths. Compatible with Extender
EF 1.4x and EF 2x. With the EOS 3, autofocusing (at the centre focusing point only) is
possible while the EF 1.4x is attached to the lens.

A truly professional L-series telephoto zoom lens with Image Stabilizer, making hand-holding practical even at its 400mm focal length.
Both a Fluorite and a Super UD-glass element ensure outstanding contrast and sharpness, and it accepts the EF Extenders 1.4x II
and 2x II. A ring-type USM makes AF fast and silent down to 5.9 feet (1.8m), and, of course, it offers full-time manual focus override.
This durable L-series lens is regarded by many pros as one of the world¿s finest telephoto zooms for hand-held outdoor use.
