Canon EF-S 55-250mm f/4-5.6 IS Lens Review

                                       
 With its 400mm-equivalent focal length, you get the reach and angle of view desirable for shooting portraits and sports, or just to bring the scenes in closer, with the image stabilization essential to keep those long telephoto shots from blurring from camera shake. The Canon EF-S 55-250mm f4-5.6 IS is a lightweight, affordable first or second lens to complement your entry-level or midrange digital SLR.

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.

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.
