High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively.
