Well-suited to wildlife, sports, and portraits, it scales up to 105–300mm on most DSLRs. Autofocus is fast and quiet, and the build robust. Sorry, though—no extra moisture or dust resistance.
An update of Sigma's pro-quality 70-200mm f/2.8 APO EX zoom of the late 1990s, Sigma's new 70-200mm f/2.8 full-frame, digitally-optimized (DG) macro zoom ($889, street) offers improved coatings for suppressing flare, dramatically closer focusing, and "full-time" manual focus that allows manual touch-up, even when set to AF. This is also the first Sigma moderate tele zoom to use elements of high-tech and expensive ELD (Extraordinary-Low-Dispersion) glass-a component of the firm's longer APO super teles-for better control of chromatic aberration.
