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 4
stops faster than the same size lens without Image Stabilizer. In other
words, if the slowest 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.
