Equipped with Canon's Optical Image Stabilizer (IS) technology, the Canon EF-S 18-55mm standard zoom lens is ideal for just about any application. IS technology compensates for camera shake by providing the equivalent effect of a shutter speed up to four stops faster. This allows you to take sharp handheld shots even in low-light conditions--a must for sports and nature photography. The lens also offers an aspherical lens element that corrects for aberration, thus producing a topnotch image throughout the zoom range, and a circular aperture that exquisitely renders out-of-focus backgrounds. Despite its minimal size, weight, and cost, the lens expands the picture-taking possibilities any time slow shutter speeds are needed.
