The-Digital-Picture have reviewed the new Sigma 24-70mm F2.8 EX DG MACRO lens.

“The Sigma 24-70mm F/2.8 EX DG Lens is a well-built, well-spec’d lens with a decent price. It does not outperform (physically or optically) Canon’s similarly spec’d EF 24-70mm f/2.8 L USM Lens, but it costs less than half as much.”
