Sigma 200mm To 500mm f/2.8 APO EX DG Zoom Lens
Some say bigger is better, and with this lens you have (perhaps) the world's most impressive commercially-produced for the general public lens every created by humankind. It's also the largest high speed ultra-telephoto zoom available. Sigma’s APO 200mm to 500mm F2.8 / 400mm to 1000mm F5.6 EX DG, is the first large-aperture ultra telephoto lens to have an F2.8 aperture at 500mm. With its specially designed attachment mounted becomes a 400-1000mm F5.6 ultra telephoto lens capable of auto-focus shooting.
It has ELD (Extraordinary Low Dispersion) and SLD (Special Low Dispersion) glass for maximum correction of aberrations. Perfect fast moving nature subjects and sports such as surfing, polo and soccer and as it excels at tracking fast moving objects it is a great surveillance lens. Here, Sigma’s achievement is unsurpassed and stands alone.
This massive ultra-telephoto zoom offers an impressively-fast f/2.8 aperture throughout its entire zoom range, all the way up to 500mm! Combined with the included dedicated high-quality 2x teleconverter, this lens can be converted for use as a 400-1000mm f/5.6 lens. Now combine this with your analog or digital SLR camera, and you got full-frame game!
If you have a APS-C sized digital SLR camera, the zoom ratio is higher! Of course this will set you back $25,999, yet on Amazon you also get some nice accessories too.
And as always, in the end what really matters is that you...
