Sigma 70mm F/2.8 EX DG Macro Lens ...- User Rating: Summary for Sigma 70mm F/2.8 EX DG Macro Lens ...- Great Macro & Wide Aperture Lens Notes on Sigma 70mm F/2.8 EX DG Macro Lens ...- I have been very please with the results obtained through this lens. It is ultra sharp, has a great macro range and the f/2.8 lets me use it as a portrait or low light lens as well!
The only slight negatives I can see are its size (will fit full frame), a little on the heavy side but reasonable for a macro lens of this size with all that glass. It does sometimes have a problem auto focusing in macro mode in low light, but I usually shoot in manual focus to get exactly what I want. The focus limiter switch greatly helps with this if you are going to shoot in auto focus though, as you can limit it to the macro range or the infinity range in addition to leaving it open to its full range of both.

If you judiciously use the focus limiter, it's perfectly suitable (actually even excellent) for portraiture. The fast aperture also helps keep ISO (and therefore noise) low, too.
