I have the 500 f/4, 100-400, 70-200 f/2.8 and the 28-135, all IS lenses too. The 500 & 70-200 lenses are exclusively used on tripods with IS engaged. They all have the jitters as the IS engages, some more than others. I don't know hundreds but I do know at least a dozen whose IS lenses do the same as mine. It's a mystery. I am not brave enough to leave all lenses set to Mode 2 all the time. I will need to experiment more.
