The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus.
The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This lens has a minimum focusing distance of 43.3inches (110cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.5.
