Sigma’s unique OS (Optical Stabiliser) technology
This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma’s original OS function. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. It offers the equivalent of using a shutter speed approximately 4 stops faster.

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.
