some great points, thanks. It makes me take another look at the quality of the 60mm macro vs the 50mm macro. I never read any comparisons because I so love the 50mm, and the 60mm was the only choice for the OMD, that I didn't want to hear that the 60mm didn't stand up well to the 50. The 50 is such a great lens that if I were building a macro rig, and the 60 was not as pretty, I'd go for the EM-1 for a macro rig just to build a rig around the 50..
love the small size of the em-5 for wide angle. I swim a lot when I'm shooting wide.
