Sigma has presented new lens for Nikon cameras which was already available for Canon devices for some time, it is the APO 200-500mm F2.8 EX DG. The big and heavy lens has weight of 15.7Kg, and a length of 726mm. In terms of technical specifications, the new APO is the “world’s first” telephoto zoom lens with an aperture of F2.8 and a focal length of 500mm. Thanks to 4 Special Low Dispersion glass elements, it is easy to make corrections and have a top-notch performance. Information about the shooting distance and focal length appears on the LCD panel, and if you want to use a filter, there’s a special spot on the rear of the lens to do so.
