You may be right, but I have used them 300mm and 600mm IS lenses on a tripod as well as my 100-400mm IS and not a problem. Maybe I was lucky. BTW, have you experienced this well known floating image yourself? I have also used the 28-135mm IS on a tripod with slow shutter speeds and the results were perfect.
