Excerpt: The news last week that Canon’s rare, 1200mm super telephoto lens was on sale again reminded us of another giant piece of glass that generated tons of buzz when it was introduced in 2008: the Sigma 200-500mm F2.8 APO EX DG.
Excerpt: With an f/2.8 aperture through its entire 200-500mm zoom range and f/5.6 at 1,000 (using its 400-1,000mm adaptor), this near-comically sized super lens from Sigma is the ultimate zoom lens for pro wildlife, sports, and astrophotographers. Granted, it’s also the size of a Fiat so prepare to check another bag if you plan to take this one on vacation. Not to get too technical, but I’m sure you’re wonder just what the hell is inside that 35 lb. green tube of awesomeness.
