Kurtmunger (Click here) tested the Tamron 60mm f/2.0 macro lens for Sony: “I would highly recommend the Tamron 60mm F/2 lens when used out in the field at longer distances, where F/2 can come in handy for getting a defocused background, or hand-held available light situations. For people wanting a good macro lens with plenty of working distance, and will be using it at close focus, I’d recommend the Sony 100mm macro.”
