Here is what Sony Support says: “I’m sorry to inform you that the Camcorder may not be able to record properly near strong radio waves or radiation. Similar is the case with the magnetic fields and mechanical vibration. Please avoid recording the Camcorder under these conditions.”
This is a MAJOR design flaw. We do event video and radios are used all the time. We knew to keep our own radios away from the camera, but we were doing a broadcast shoot for Time Warner and the scorekeeper about 3 feet away had a radio and our main camera went all blurry a few times because of this. Guess its time to get rid of the Sony and pick-up some more Panasonic AC130s.
