Excellent Optical Performance
It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations.
HSM
An inner focusing system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched petal-type lens hood (supplied) and circular polarising filters.
Close-up photography
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability.
Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.
