Thanks for the comments,

I also noticed that the IS is running constantly. Fortunately there is the switch on the lens to turn it off so you don't eat up your battery needlessly. With my 550D it was running only when focusing and may be 2 seconds after that.

I wonder if it's just my lens then that does the restless focus hunting, then. I tested the lens now, and for the most part the images seem to be in focus anyway, so it's still usable.
