Canon EF 100-400mm f/4.5-5.6L IS II USM Camera Lens

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. This lens is compatible with Extender EF 1.4x and EF 2x. Fluorite and Super UD glass completely eliminate secondary spectrum for superb color rendition. Autofocusing is fast and silent with Canon's ring USM, and AF speed is further enhanced through an advanced, lightweight rear focusing design that incorporates a floating element for consistent image quality at all focusing distances. 

This lens is also equipped with a dual-mode Image Stabilizer suitable for panning as well as stationary subjects. With full-time manual focus, one-touch zooming with a wide grip, and a special ring that permits adjustment of zooming friction, this is a lens that's extremely easy to use, and ideal for a wide variety of applications including nature, wildlife, sports, and documentary photography.
