This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function.   The lens incorporates SLD (Special Low Dispersion) glass in the front lens groups and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range.

The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady, handheld photography.
