I’ve finished the Sony 100mm F/2.8 macro review. Click here to check it out. If you’ve read the macro lens shootout, you already know about the lens. On a side note: I sent my Sigma 18-50mm F/2.8 back to the factory to have them check the focus. They had it a month. When I got it back I checked it out—it had the same poor focusing problems as before. But all is not lost! When I opened the box the lens came in, I noticed they included a nice lens cleaning cloth with the Sigma logo! I guess that’ll make me forget the $419 I wasted.
