2. Olympus image stabilization is preferable if you already own (or plan to purchase) Panny stabilized lenses.

Thank-you so much for this detailed analysis!. I own a G1, with a broken internal flash, the kit lens plus a 45-200 also from Pana, and an Oly flash. Your point 2 intrigues me: so in-lens stabilization adds to in-body stabilzation? With slow shutter speeds I should keep both on if I use those lenses on an OMD?

No. What bowportes tries to say is that he thinks it is better to use the stabilization in the E-M5 body (IBIS) than the stabilization in the Panasonic lens (OIS) when both are available. Under no circumstance should you try to use both at the same time. When both are active simultaneously, they will overcompensate for camera shake with blur as a result.

Personally, I disagree with his judgment about which of the two systems to use when both are available, at least for the OIS lenses I have. Two of those are probably the same as yours (my older body is a G1 which I bought used together with a 14-45 and a 45-200). With the 14-45, I use OIS rather than IBIS since the OIS on this particular lens, unlike IBIS, is able to counteract the shutter shock that may cause blur at certain shutter speeds (around 1/100 s). With my other OIS lenses (45-200, 100-300), I don't see much of a difference between OIS and IBIS. In practice, this means that I usually keep IBIS on (since it works with pretty much all my lenses, zooms and primes, Oly and Pany) but turn it off when I mount the 14-45.

If you parse the structure of my post, I prefaced the entire second list with "this does NOT necessarily mean."  What I intended to say was, "This does NOT mean ... that Olympus image stabilization (IBIS) is preferable if you already own Panny stabilized lenses." In other words, "the stabilization you already have with Panny OIS may be about as good as what you would get on the EM5 through IBIS."  I was trying to leave it open, and noting that the extent to which IBIS is an EM5 advantage depends upon the lenses.  For someone who owns the Panny 12-35mm and 35-100mm and doesn't plan to use any other lenses, the EM5's IBIS isn't really an advantage over the G5.  I wasn't very clear. Maybe this is clearer.
