APO 70-200mm F2.8 EX DG / HSM
Four Special Low Dispersion (SLD) glass elements produce excellent image quality throughout the entire zoom range.
New coating and lens design minimise flare and ghost.
Inner focusing and inner zooming systems retain external dimensions for ease of handling.
The HSM models provide silent, high-speed and precise auto-focusing with full time manual focus override.
Sigma Corporation is pleased to announce the launch of the new APO 70-200mm F2.8 EX DG / HSM lens.
This telephoto zoom lens has a large maximum aperture of f2.8 which remains constant throughout the zoom range and it is optimised for digital SLR cameras.Two pieces of SLD (the special low dispersion) glass in the front lens group and another two in the rear group offer excellent correction of chromatic aberration. High optical performance is demonstrated throughout the entire zoom range.
The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance.
An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood supplied and circular polarising filters. Since focusing and zooming do not change its overall length, ease of handling and operation is assured. A rotating tripod mount can be conveniently detached if required.The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon-D mount lenses.
The lens can be used with the 1.4x EX or 2.0x EX Apo Tele Converters (optional), becoming a 98-280mm F4 Autofocus telephoto zoom lens or a 140-400mm F5.6 Autofocus telephoto zoom lens respectively.
