Canon EF-S 55-250mm f/4.0-5.6 IS II Telephoto Zoom Lens for Canon Digital SLR Cameras
Incorporating Canon's Optical Image Stabilizer technology, this Canon 55-250mm telephoto zoom lens captures long distance, low-light shots far better than many comparable lenses, helping you photograph the far-off action of athletes or zoom in for an intimate portrait with a blurred background. The 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). More significantly, the image stabilizer effect creates an equivalent shutter speed of roughly four stops faster than the same size lens without an image stabilizer. In other words, if the slowest shutter speed you can hold a 250mm lens steadily is normally 1/250th of a second, this Canon lens will let you hand-hold shutter speeds as slow as 1/15th of a second. The lens also boasts a UD-glass lens element to correct chromatic aberration to create excellent image quality throughout the zoom range. Delivering an excellent performance at an affordable price for all photographers, the 55-250mm lens carries a one-year warranty.SpecificationsFocal length: 55-250mmMaximum aperture: f/4 to f/5.6Lens construction: 12 elements in 10 groups, including one UD-glass elementDiagonal angle of view: 27 degrees (at 50 feet) to 6 degrees (at 15 feet), with APS-C image sensorsFocus adjustment: DC motor, gear-driven (front focusing design)Closest focusing distance: 3.6 feet (0.31x maximum close-up magnification)Filter size: 58mmDimensions: 2.8 inches in diameter and 4.3 inches longWeight: 13.8 ouncesWarranty: 1 yearThis telephoto zoom lens is designed with Canon's Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. 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), and the image stabilizer effect 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.
