I was using a 2x Extender with the 300mm on an EOS3, with a remote switch. The ball-head was locked up solid, as I was shooting in a permanent hide in one of the local nature reserves. I did not use mirror lock-up. I didn't actually take any shots like this, but turned IS off when I saw the floating effect, so it may have had no effect, but I don't know. With a loose head for panning, I would certainly leave IS on.
