It features an 18-200mm zoom ratio (the 35mm film equivalent focal length is 29-320mm) and has a maximum aperture of f/3.5-5.6. Designed to appeal to entry-level and advanced amateur users looking for a lens with an optical Image Stabilizer and large focal length range, it weighs just 595g and 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 Autofocus Lens features a 4 stop Image Stabiliser (IS) extends low light options to previously unavailable levels. Photographers normally shooting handheld at 1/250 sec can switch on IS to obtain a similarly steady and blur-free result with a shutter speed of just 1/15 second. Image blur in low light and at long telephoto lengths is significantly reduced. The zoom ring can be locked in place at its widest focal length in order to prevent the lens from physically extending while not in use.
Two UD (Ultra-low Dispersion) elements and several aspherical elements are used to suppress the effects of secondary chromatic aberrations, to obtain crisp, sharp, high-contrast images without fringing throughout the zoom range. Optimised Super Spectra lens coatings and lens element shaping, suppress flare and ghosting. Coatings also help achieve true color balance and increase contrast for vivid hi-fidelity images.
