The Canon EF-S 55-250mm f/4-5.6 IS Lens is a compact and lightweight telephoto zoom lens that is specifically designed for the range of EOS digital SLR cameras that use the smaller EF-S lens mount. Combining powerful performance with high image quality, this lens offers the equivalent of 88-400mm in 35mm format, and is ideal for photographers seeking an affordable, versatile lens for general-purpose telephoto photography. The EF-S 55-250mm f/4-5.6 IS Lens incorporates Canon's 4-stop compensation Image Stabilizer technology. This allows the use of shutter speeds up to 4 times slower with no perceptible increase in image blur. Automatic panning detection automatically turns off the Image Stabiliser in either the horizontal or vertical direction when following moving subjects.
