OK, so now I have the 100-300. Question: Lens OIS on and IS in camera off? In a few quick tests that seems to be the way to go. And I can probably live with the camera IS off most of the time out doors anyway. It's actually smaller than I thought it would be. I mean I'm not going to carry it in my cargo pants pocket like I can with the 14-42. But still easily manageable. Still need to decide between the Pan 14 or the body cap lens.
