Compact, lightweight and a wide magnification range - this standard
zoom lens features a wide focal length range from normal to telephoto
equivalent to 29-320mm in the 35mm format. It features an Optical
Image Stabilizer for up to 4-stops of effective correction even at
full zoom. Since Canon's optical image stabilization system is in the
lens, not in the camera, you can see the stabilized, steadier images
through the viewfinder. And the circular aperture can give beautiful
background blur effects. This new wide zoom ratio EF-S lens delivers
excellent high-speed performance at an affordable price.
