The Sigma Corporation began production of the DG wide-angle lens series in 2000. This range has grown to include 13 models by February 14th 2005. Sigma is now launching ten new EX DG telephoto lenses including three fixed focal length telephoto lenses.

come complete with matched lens hoods and fitted padded cases. HSM focusing
is used extensively throughout the range.
50-500mm F4-6.3 APO EX DG
This lens ensures a superior level of precision from 50mm standard to 500mm ultra telephoto. Four Special Low Dispersion (SLD) glass elements effectively compensate for chromatic aberrations. High optical performance is demonstrated throughout the entire zoom range.

80-400mm F4.5-5.6 APO EX DG OS
Using Sigma’s original OS (Optical Stabiliser) function, two types of sensors inside the lens detect vertical and horizontal movement of the camera. By moving a portion of the optical system to compensate for movement, this function delivers outstanding results in compensating for camera shake.
