From the ManufacturerEquipped with Canon's Optical Image Stabilizer (IS) technology, the Canon EF-S 18-55mm II 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.SpecificationsFocal length: 18 to 55mm Maximum aperture: f/3.5 to f/5.6 Lens construction: 11 elements in 9 groups Angle of view: 74 degrees @ 20 feet to 27 degrees @ 50 feet Focus adjustment: Autofocus (DC motor) with manual focus option Closest focusing distance: 9.8 inches Filter size: 58mm Dimensions: 2.7 inches in diameter and 3.33 inches long Weight: 7.1 ounces Warranty: 1 yearProduct DescriptionThe Canon 2042B002 EF 18-55mm f/3.5-5.6 IS II Zoom Lens is a standard zoom lens designed with Canon's Optical Image Stabilizer technology while retaining the compactness and lightness of previous models.
