The Canon Zoom Telephoto EF 100-400mm f/4.5-5.6L IS (Image Stabilizer) USM Autofocus Lens is the first EF lens with a zoom range from 100mm to 400mm. This EF 100-400mm f/4.5- 5.6L IS USM lens delivers high resolution, superb contrast, neutral color balance, as well as Canon’s built-in Image Stabilizer. High zoom magnification is made possible by a 6-group lens configuration with 5 movable groups.

Autofocusing is fast and silent with Canon’s ring USM. The AF speed is further enhanced by an advanced, lightweight rear focusing design that incorporates a floating element for consistent image quality at all focus distances, from 5.9′ on. Fluorite and Super UD glass eliminate secondary spectrum for superb color rendition.
