One of Sigma Corporation’s well known products is the Sigma 200-500mm f/2.8 APO EX DG Ultra-Telephoto Zoom Lens, a professional-level telephoto lens made for Canon digital SLR’s. So if you’re turning serious about your picture-taking hobby and want to move on to being a professional photographer, you could include this behemoth of a zoom lens.
But first, you had to have sufficient funds to buy that because its retail price goes around $25,000. From the price alone, this lens is certainly no joke. Second, it is quite hefty as it weighs 16 kilograms (35 lbs), so make sure your arms are strong enough to lug this gigantic lens around. But it sure makes a good upper-body workout!
This lens is quite fast for a standard photograhy, as it has f/2.8 aperture even at 500mm, which allows distant objects to be shot at high-shutter speeds in a dimly-lit environment. Plus, this 200-500mm comes with a dedicated 2x teleconverter to turn it into a 400-1000mm f/5.6 autofocus. A 72mm filter holder can be inserted at the back of the lens. The lens hood, on the other hand, blocks out unnecessary light.
The Sigma 200-500mm f/2.8 APO EX DG Ultra-Telephoto Zoom Lens runs on a dedicated Li-on battery to provide the power needed for focusing and zooming. This lens is available for Sigma, Canon and Nikon mounts.
