This telephoto zoom lens is designed with Canon's Optical Image Stabilizer
technology while retaining compactness and lightness, in response to
demands of photographers. This high zoom ratio lens is equivalent to a focal
length of 88-400mm in the 35mm format (when used on Canon EOS
cameras compatible with EF-S lenses), and the image stabilizer effect
equivalent to a shutter speed about 4stops faster than the same size lens
without Image Stabilizer. In other words, if theslowest shutter speed you
could formerly hold a 250mm lens steadily was 1/250th of a second, with
Canon's 4-stop stabilization correction, you could hand-hold at shutter
speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to
correct chromatic aberration for excellent image quality throughout the zoom
range. This new EF-S telephoto lens with great features delivers excellent
performance at an affordable price for all photographers.
