E-PM1 (and probably E-PL3 as well since they had the same sensor-shutter assembly) had problems with IBIS, it was basically unusable (not all cameras seemed to have that problem, but it was widespread nonetheless). My E-P2, on the other hand, had excellent stabilization system, and E-M5 is even better in this regard, even beating all the Panasonic lenses' stabilization systems.
