Is anyone aware of better macro lens for the Olympus EM-5 micro 4/3's camera than the 12-50mm lens that has macro built in?
The Olympus 12-50mm provides 1:3 magnification, so it's technically not a macro lens but a good close-up lens. True "macro" lenses have at least 1:1 magnification. Still, it's pretty good, and Robin Wong had a nice post reviewing the capabilities:

The Olympus 60mm f/2.8 for m4/3 is a great lens, including for use as a macro lens since it does 1:1 macro. Close focus distance is about 3.5"
The Olympus 50mm f/2 for 4/3 is also a great lens; it does 1:2 but will do 1:1 with the EX-25 extension tube. Close focus distance is about 2". It will not auto focus very quickly with the EM5, but it's usable (I've used it on an EM5 and gotten great shots). The advantage of the 50mm is you can also use the EC-14 or EC-20 teleconverters on the lens.
I also use the Nikon Micro-Nikkor 105mm f/2.8 AI-s. It does 1:2, but with the PN11 extension tube it does 1:1 and the extension tube has a tripod collar which is really handy. Close focus distance is about 6". Add the Nikon E2 extension with aperture button and you can easily open the aperture for focus and close for exposure. And its a nice lens for normal shooting.
And there is the Nikon Micro-Nikkor-P 55mm f/3.5. It does 1:2, but with the M2 extension tube it does 1:1. The lens is too slow for use other than macro.
Finally, there is the Olympus 35mm f/3.5 for 4/3; it does 1:1 macro but it's focal length is so short you have to really get close to your subject. Close focus distance is about 1".
If you can find one, the Olympus SRF-11 ring flash or STF-22 twin flash attach to all three macro lenses, but are effective only with the 60mm. The FR-1 adapter for the 50mm and 35mm is 2" deep, which is not compatible with the close focus distances of these lenses. The FR-2 adapter for the 60mm, however, is only 1" deep and that leaves some room (but not much)
I have modified an FR-2 adapter for use with a step-up ring, and that helps with the 50mm but also means I can mount the flash on the Nikon lenses. With the Nikon 105mm, that makes for an awesome combination with very good working distance.
I also have a Nikon SB-21 Macro Speedlite, its really a twin flash unit, but it has a 52mm screw on adapter so it works native with everything but the 60mm (which needs a step-up ring). That's a totally manual flash setup, but it works well enough.
My recommendations will depend upon how manual you want to go. If you don't mind manual, then the Nikon 105mm plus extension tubes has the best working distance, which is important for flexibility in lighting. It is long (8") and heavy, so hand holding is difficult, but the working distance is very good.
Otherwise, the 60mm f/2.8 provides good auto focus and exposure, but has less working distance. It is out of the box compatible with the Olympus ring flash, and it is light.
