Shutter Slap? your thinking thats what is causing the blurred EM5 shots?

My E-M5 has shutter shock issues between 1/20 and 1/200 (approximately) with the 100-300 as well as other longer lenses (40-150, 45-200, 75/1.8) and I have reasons to think that I have tested this more carefully than just about anyone else on this forum. For the 100-300, you need at least 1/250, preferably 1/320 regardless of whether you use IBIS or OIS. With the 100-300 at 300, the impact of the shock is clearly visible even when shooting from a pretty good tripod with long anti-shock enabled.

I put it down to IBIS and my technique first round...we shall see soon I'll shoot them all side x side birding and compare shutter speed, ISO, and F-Stops...

I don't think IBIS is causing the problem. It's just that it can't correct for the shutter shock, presumably because the speed/frequencies involved are far higher than those of human handshake. OIS can't either. The only lens where I have found a difference between IBIS and OIS when it comes to the ability to counter the shutter shock is with the 14-45. In this case, OIS is preferable on that ground.

Yes, I found the shutter slap is a limiting factor, even on my GH3.  I agree that 1/250s is a good starting point for consistent results.  But I have been finding good results with 1/200s if I use the Hi-speed burst as the shutter doesn't stay open between shots so there is less vibration after the first shot.  The negative is that you loose liveview but the slightly faster shutters speed is worth it to me.  I have tried the silent shutter but I noticed at most an additional 1/3 stop improvement but was concerned about the slow sensor read where movement can be skewed.  So the OIS also seems to be limited and not much benefit with the silent shutter in my use.
