You might not have noticed because of its massive girth, but the Sigma 200-500mm lens actually has a camera connected to its huge mass. And it just goes to show you how incredibly huge this APO F2.8 lens really is. The EX DG is the first lens that offers a fast F2.8 aperture at a lens size of 500mm while maintaining the fast speed even when zoomed. The lens also comes equipped with an LCD panel to preview your focal points and shooting distance.
A standard accessory of the EX DG is an APO Tele Converter 2x EX DG II, which is supplied with the massive Sigma lens and offers even more reach than the already massive 500mm. This thing is so huge it needs its own handle. — Andrew Dobrow
