OMD versus G5, IQ

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.
