Sigma 24-70mm F/2.8 EX Macro Review
Photopurity has taken some time to review the 24-70mm F/2.8 EX DG Macro lens from Sigma. When it comes to non-OEM lenses you’ll find that many photographers downplay the performance of Sigma and Tamron the two largest third party optic vendors.

I’ve handled dozens of optics from both Sigma and Tamron (as well as Tokina and a few others) and my general conclusion is that this reputation is born of either ignorance or perhaps a ...
