"Bring your photographic subjects closer with this Canon EF-S 55-250mm f/4-5.6 IS Image Stabilizer Telephoto Zoom Lens. It is designed with Canon's Optical Image Stabilizer technology and is compact and light. 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). The image stabilizer effect is 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. Filter Size - 58mm Max. Diameter - x Length 2.8 in. x 4.3 in./70 x 108mm (maximum lens length) Weight - 13.8 oz./390g Canon 1 year limited warranty"

"High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm f/4L USM."
