The first EF lens with a zoom range from 100mm to
400mm, the EF 100-400mm f/4.5- 5.6L IS USM lens offers high resolution, superb
contrast, neutral color balance, and Canon's original built-in Image Stabilizer
function. High zoom magnification is achieved by means of a 6-group
configuration with 5 movable groups. 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 from 5.9' to infinity.
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.
