Sigma 70-200mm F2.8 EX DG OS HSM for Canon DSLRs (EF and EF-S Mount)
Canon shooters—APS-C format and full-frame DSLRs alike—seeking a fast (f/2.8), well corrected (two FLD and three SLD elements), short-to-midrange tele zoom might want to have a look-see at the pro-quality attributes of the new Sigma 70–200mm f/2.8 EX DG OS HSM zoom lens.
Fast zooms in the 70-200mm range have long been popular among pro and semi-pro shooters alike, and this is the audience at which Sigma has taken aim with the release of their new 70-200mm F/2.8 EX DG OS HSM. Containing a whopping 22 elements in 17 groups, including two FLD extra-low dispersion glass elements, three SLD (Special Low Dispersion) glass elements and Super Multi-Layer coatings all around, the Sigma 70-200mm F/2.8 EX DG OS HSM has targeted a group known for pickiness when it comes to optics.
Like similarly ranked OEM 70-200mm f/2.8 zooms the new lens is going up against, the Sigma 70-200mm F/2.8 EX DG OS HSM contains many of the features seekers of this class of lens expect. Included among them are a 9 curve-bladed diaphragm for natural looking out-of-focus highlights (nice bokeh), a compact barrel length (7.8" / 8.64cm), a removable tripod collar, HSM motors, up to four stops of image stabilization and close focusing down to 55.1" (140cm).
Included with the Sigma 70–200mm F/2.8 EX DG OS HSM is a soft pouch with strap, front and rear caps, a tulip-style hood, the aforementioned removable tripod collar and a 3-year extended USA warranty.
