With close-focusing to 7.25 inches and magnification at 1:2.6, it’s perfect for tabletop shooters. Our tests found it optically superior to some pricier glass.
With Sigma's new 18-50mm f/2.8 macro ($420, estimated street), we jog past another milestone: This was the industry's first digital-only lens to be released in a secondgeneration version. The closest focusing of any Sigma zoom, this 30-85mm (equivalent, with our test camera's 1.6X lens factor) features a wider barrel and larger filter size, and much closer focusing (from 7.25 inches, rather than 11.25 inches) than the 18-50mm it replaces, at about the same price.
