Today’s eBay Daily Deal: BuyDig via eBay has the optically-stabilized Sigma 17-50mm F2.8 EX DC OS HSM for Canon for $429.99. They’re an authorized Sigma retailer, and this ties for the lowest price from an authorized dealer that we’ve seen, since tracking this lens in 2011.
Compare with other authorized retailers who are currently asking $569 for this lens. This lens was due for a price-drop as the Canon equivalent EF-S 17-55mm f/2.8 IS saw a price drop from $1059 to $829 last year. At a little more than half the price, this Sigma version is a fantastic deal.
