Sigma also introduced a new telephoto zoom lens at the PMA show. It is the totally new designed 70-200 F2.8 with a very short minimum focusing distance. From the outside it looks a lot like the old one but internally it is a completely new optical design. It is expected to be ready in June/July.

Sigma Press release:
Sigma Corporation is pleased to announce the launch of the new APO 70-200mm F2.8 EX DG MACRO HSM lens. This large aperture telephoto zoom lens has a minimum focusing distance of 100cm (39.4”) throughout the entire zoom range. It is very convenient for close-up photography. This lens uses two ELD (Extraordinary Low Dispersion) glasses and two SLD（Special Low Dispersion） glasses for utmost correction against chromatic aberrations.

This lens’ super multi layer lens coating reduce flare and ghost, which is a common problem with digital cameras. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF. The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling. A removable long tripod collar (TS-41) is included as a standard component. When this lens is used with the 1.4x EX DG APO or 2x EX DG APO Tele Converters (optional), it becomes a 98-280mm F4 AF telephoto zoom lens or a 140-400mm F5.6 AF telephoto zoom lens respectively.
