Compact proportions with a powerful zoom range of 11x – make an ideal general-purpose zoom for photographers on the go. Great low-light performance is assured by a 4-stop Image Stabilizer. The EF-S 18-200mm f/3.5-5.6 IS is a compact, EF-S lens with high magnification – approx. 11x. It features an 18-200mm zoom ratio (the 35mm film equivalent focal length is 29-320mm) & has a maximum aperture of f/3.5-5.6. Designed to appeal to entry-level & advanced amateur users looking for a lens with an optical Image Stabilizer & large focal length range, it weighs just 595g & measures 78.6 x 102mm. The lens offers 0.45m minimum focusing distance at all zoom position. The EF-S 18-200mm f/3.5-5.6 IS is designed exclusively for use with EOS cameras featuring an EF-S lens mount – including the EOS 50D, EOS 1000D, EOS 450D, & earlier models. High image quality has been assured with the addition of two high-precision aspheric lenses to correct aberration including curvature of field & distortion. Chromatic aberration common in wide-angle shooting is also combated by the inclusion of two UD lenses, ensuring optimum image quality & corner-to-corner detail. Canon’s patented lens element coating minimises the ghosting & flare caused by reflections off the camera image sensor & internal lens surfaces. Light transmission is enhanced & reflections are reduced to deliver clear crisp images. A 4-stop optical Image Stabilizer – specially designed for the lens’ specific focal length range – works to counteract image blur, which can occur during handheld shooting, or at slow shutter speeds. Automatic panning detection ensures effective performance when tracking moving subjects. &, as the IS system is based in the lens, results are visible through the viewfinder during framing. 11x zoom lens – 18-200mm 4 stop Image Stabilizer Automatic panning & tripod detection Close focusing distance of 0.45m Aspherical & UD lens elements Super-Spectra lens coatings combat ghosting & flare Zoom lock maintains minimum size Circular aperture for pleasing background blur
