I set out to test the effectiveness of the E-PM2 image stabilization against that of the E-M5 using the Olympus 75mm f/1.8 lens at a variety of shutter speeds with or without in-body image stabilization (IBIS, mode 1) engaged. For each setting I took 10 handheld images without burst mode, refocusing for each shot. 100% center crops are shown below for each series. All samples are presented below without commentary. Main findings: -E-M5 IBIS is more effective than E-PM2 IBIS, especially at low shutter speeds. -At all shutter speeds with both cameras, IBIS gave more consistent results than no IBIS. -At 1/100s, the sharpest results from both cameras came with IBIS off. This was particularly noticeable with the E-PM2, where none of the shots with IBIS on were critically sharp. UPDATE: Kyle and Art made me aware of the role for the anti-shock setting. I set it to 1/8s as they suggested and got the following results with the E-M5: Seems to me that this setting completely addresses the issue with IBIS at 1/100s, albeit at the expense of a slight increase in shutter lag and viewfinder blackout time.. Preliminary results are that even with this setting the E-PM2 results were not ideal at 1/100s. I'm continuing to look at this and will update with any new findings.
