I have only ever used Olympus lenses so find I am unsure about the best settings with the Panasonic 12-32 lens. My initial tests show IS not seeming to work well, with blurred shots at 1/60. 1. In Menu C should I have Lens IS Priority on or off. Is this setting even relevant to Panasonic lenses? Initially I had this OFF. If it is ON, does that turn off the camera's IS? I'm guessing I should leave it Off? 2. In Menu K, do the Lens Info Settings have anything to do with IS? If they do, what should I set it to 12mm or 18mm or 32mm?
