Of course, I could shoot FF at 2.8, but then I'd also be shooting at an ISO of 12800 for the same shutter speed.  Even as good as FF images are, the OM-D at 1/4 the ISO will always look better.

Is this true though?  At the moment, it appears to be true with the OM-D, but that's only because of the efficiency of that Sony sensor.  In the past, on other 4/3 and m4/3 models it has been otherwise, there has been more than a 2 stop ISO difference in some cases.  Even now though, is there much difference in these samples?

If the sensors were equally efficient, then there would pretty much be no case where m4/3 had an inherent advantage other than size, convenience, and cost.

On the other hand, I think we are also getting to where there are fewer and fewer situations in which full frame has any practical advantage that would be worth the difference in cost.
