Have had my D 60 for over a year and have only had this problem recently. Up until I got a Canon 70-200 2.8L IS I would always leave the camera in my bag without a lens and the dust cap on. Since I have this new lens, (and a new bag in order to hold it all) I have been leaving the 70-200 on the camera with camera switched off. Twice now after having left it in the case for about a week, both batteries are completely drained. Oh, yea, I have the battery grip on the camera as well, but I have always had it this way.
Will Canon's 70-200 2.8L IS drain batteries if left attached to the body??
Anyone else had this??
