Sigma Launches DG Version of Ten Telephoto Lenses

The Sigma Corporation is pleased to announce the launch of ten DG EX telephoto lenses.
The recent rapid growth of the digital single lens reflex (SLR) camera market has greatly increased the demand for digitally optimised lenses.

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. The EX DG telephoto lens series is designed to deliver ultra high performance with digital SLR cameras.

The following lenses are all fully dedicated and matched to work with our 1.4x and 2x tele converters giving the utmost in image quality. All these 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.

70-200mm F2.8 APO EX DG
A popular telephoto zoom lens with a large constant maximum aperture of F2.8. Four Special Low Dispersion (SLD) glass elements ensure high quality images at all zoom settings. Featuring HSM technology and internal focusing, this lens offers fast and quiet auto focusing without rotating the front element.

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.

100-300mm F4 APO EX DG
This telephoto zoom lens provides a large F4 aperture at all focal lengths. With minimal light fall-off, superior peripheral brightness is ensured. It’s an ideal lens for digital SLR cameras. Internal focus design and HSM system for silent and high speed auto focus.
