Re: Why do you have to turn off IS/VR?
It's not the non existence of vibrations. But when you mount it on a tripod, the tripod itself can vibrate but at frequency which the VR/IS cannot keep up. Find the longest lens and mount it on a tripod, then tap it and see how fast it vibrates compares to holding it in your hand and you'll know what I mean. It has to do with the vibration properties of solid beams.
