The Sigma Corporation is pleased to announce the new APO 200-500mm F2.8 EX DG. Lens.

This lens is the world’s first ultra telephoto zoom lens that offers a fast aperture of F2.8 at the 500mm focal length.  It covers widely used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. 

This lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports.  SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations.  The super multi-layer lens coating reduces flare and ghosting and provides high image quality from the extremely large aperture. 

The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. 

The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation.  This battery is housed within the lens body.  The addition of a specifically designed dedicated “Attachment” produces a 400-1000mm F5.6 ultra telephoto zoom lens that still retains auto focus. For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens` built-in LCD panel.
