Do you use IS when you shoot football where your shutter speed exceeds the 1/focal length rule of thumb with a super telephoto lens? If I shot at 1/1000s with a 400mm super telephoto lens, should I turn IS mode on 2 or 3 or leave it off?
This question probably is more tailored to those that shoot college/pro football with good stadium lighting.
I've shot noon games before with a 70-200mm and always left IS off.
