Thank you JRS for your comment and very useful info and very accurate. However, I do shoot all the time with the IS off when on a tripod. I can not hand hold very well at all and still have camera shake quite a bit with IS lenses and that is why I have to chose wisely on what I handhold and what I don't. I try to leave wildlife and equestrian to handholding and everything else to tripod or I am very unhappy with the results. I wish I could say that I didn't turn it off and go back out and shoot with it off and have this whole mess be done with, but I can't.
Thanks again..
