In the past I've used my 50-200 lens and a 1" extension tube to shoot macros but I finally broke down and bought my first macro lens, an Olympus M.Zuiko ED 60mm f2.8. On my E-M1 camera the lens functions as a 120mm [35mm equivalent] focal length and should make a nice portrait lens as well. I've just taken a few test shots with it and so far I'm pretty happy with it.
