I know the IQ topic and double line issue have been covered extensively in other posts but I could not find the answer to this question: Can I completely disable the OIS Of the Panny 45-175 on an E-M5? It seems to me that if I disable the IBIS, then the lens OIS is turned on. The lens does not have a switch to turn it off. I am asking because I bought the Panasonic on the Amazon Gold Box deals last week. Wanting to see if the lens experienced the double line issue, I proceeded to take comparison shots with both lenses. Sure enough, on tripod, at 1/125, the Panny's images are blurry compared to the Oly. But if I take the Panny off the tripod, turn IBIS on, I actually get better results than with the Oly. It's a bit counter intuitive!
