I've poked around the Mu-43 forums but can't find the answer to this question: when mounting a P 12-35 f/2.8 on an E-P5, is there any reason to favor the Power OIS on the lens vs. the 5-axis S-IS built into the body? Any reason to have both turned on at the same time? I'm guessing the answer to the latter question is, "Don't do it!" because the 5-axis probably uses accelerometers in the body and doesn't know that the lens might be stabilized independently. Great forum. I've learned so much already: thanks!
