There are a lot of crazy lenses out there, whether by design or price (some by both), and the Sigma APO 200-500mm f/2.8 EX DG sits near the top of both those categories. Not many photographers ever get the privilege to shoot with one, but this camera reviewer did, and this awesome video takes a look at his experience with this ridiculous lens.
Coming to you from Christopher Frost, this neat video review takes a look at the Sigma APO 200-500mm f/2.8 EX DG. f/2.8 is generally the standard aperture of professional-level zoom lenses and supertelephoto primes — that is until you get into the longest focal lengths (past 400mm). And that is what makes the Sigma lens so ridiculous: not only is it an f/2.8 lens that reaches 500mm (and is the only one to do so to my knowledge), it is also a zoom lens, which explains aspects like its need for its own dedicated battery and its eye-watering price tag (normally around $25,000). Without a doubt, there is no other lens out there like it, and while pretty much none of us will ever get a chance to use it, it is still quite fun to see what you can do with it. Check out the video above to see it in action.
