I have to agree with Paul on this one. The general advice in the photo world is to turn off SR/VR/IS when the camera is supported or when panning. In reality, I've almost always forget to turn it off, and haven't ever had an image degraded because of it. Now, I just leave it on and foget about it. If I were to have a problem I would shut it off. As with many things, I read the instructions and then do what works.
