Received news earlier today that sigma have announced the intended launch of a 200mm-500mm F2.8 lens, in both Canon and Nikon fit. I have already asked Ray Fitchett of Sigma UK for a look at one as soon as possible. As yet there is no announcement on price or availability.
“NEW PRODUCT INFORMATION 8th March 2007
APO 200-500mm F2.8 EX DG
The world’s first Ultra-Telephoto Zoom Lens that offers a fast aperture of F2.8 at 500mm focal length
The Sigma Corporation is pleased to announce the launch of the new APO 200-500mm F2.8 EX DG Ultra-Telephoto zoom lens.
The APO 200-500mm F2.8 EX DG is the world’s first Ultra-Telephoto zoom lens that offers a fast aperture of F2.8 at 500mm focal length. It covers the widely used 200 to 500mm focal length range, and maintains its fast F2.8 aperture over the entire zoom range. Four SLD (Special Low Dispersion) glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
Shooting distance and focal length can be viewed on the lens’ LCD panel, which is an additional convenience for the photographer.
A filter can be inserted towards the rear of the lens, and a circular polarizing filter can be used with its ingenious rotation mechanism.
A dedicated 2x APO Tele Converter EX DG II is supplied as a standard accessory with the APO 200-500mm F2.8 EX DG.
Its exclusive design minimises image degradation usually associated with tele converters. When this dedicated tele converter is used with the APO 200-500mm F2.8 EX DG lens, it becomes a large aperture 400-1000mm F5.6 AF Ultra-Telephoto Zoom lens.
Further details and UK SRP are still to be announced.”
This may be a picture of a mock up the lens, as judging by the way it is being help, it doesn’t look as though it is heavy enough to be the real thing. I think that is also a very large lenshood fitted.
