The 18-200mm f/3.5-6.3 DC Macro OS HSM C (Contemporary) Lens For canon
Digital Cameras from sigma is an all-in-one lens covering an 11x zoom from
wide-angle to telephoto, with a 35mm equivalent focal length of 27-300mm. An
optical stabiliser (OS) system is built into the lens, which reduces the
appearance of camera shake. This can be especially helpful when shooting at
long focal lengths or up-close macro shots. OS also allows you to use slightly
longer shutter speeds, making it possible to shoot hand-held in low-light
conditions. The built-in Hyper Sonic Motor delivers quick and quiet autofocus.
