Thank you for purchasing a Canon product. The Canon EF-S55-250mm f/4-5.6 IS lens is a high-performance telephoto zoom lens equipped with an Image Stabilizer, and has been developed for digital SLRs compatible with EF-S lenses*. It is equipped with an Image Stabilizer effective for hand-held shooting at slow shutter speeds. * As of February 2010, only the EOS 7D, EOS 50D, EOS 40D, EOS 30D, EOS 20D, EOS 20Da, EOS REBEL T2i/550D, EOS REBEL T1i/500D, EOS REBEL XSi/450D, EOS REBEL XS/1000D, EOS DIGITAL REBEL XTi/400D DIGITAL, EOS DIGITAL REBEL XT/350D DIGITAL, and EOS DIGITAL REBEL/300D DIGITAL are compatible with EF-S lenses. ¡"IS" stands for Image Stabilizer. Conventions used in this instruction Features 1. The Image Stabilizer gives the equivalent effect of a shutter speed four stops faster*. This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots). 2. UD lens elements for excellent imaging performance. 3. Great close-ups at 1.1 m/3.6 ft at all focal lengths. 4. A truly round aperture hole results in a nicer background blur. * Based on [1/(focal length x 1.6)] second. Generally, it requires a shutter speed [1/focal length] second or faster to prevent camera shake (in 35mm format. With an EF-S lens, it would be [1/(focal length x 1.6)] second). Warning to prevent lens or camera malfunction or damage. Supplementary notes on using the lens and taking pictures. ENG-1
