Olympus 60mm/f.2.8 macro for m4/3: Multiple floating element internal focusing to 1:1 true macro... 6.53 ounces in weight... Weather resistant... Slim design with arguably Olympus's best manual focusing* and overall handling. Sharp wide open at all distances. I own it. ...BTW, E-PM2 bodies are really cheap now; use also with your telephotos for reach, and with DA Limited lenses in MF with aperture-setting adapter [i.e., Fotodiox].
* Qualification: Being an m4/3 lens, it is focus-by-wire in MF mode. But macro/close-up can be a different game with IBIS and tilt, touch-screen auto-focus (E-PL5, et.al.)
