Well, I'll believe you, but it seems unusual to me. If I pick up a metal rod, and hold it by the end, it will ring more than if it I hold it at more balanced position. But, I can also see how the lens tripod mount would act as a fulcrum producing a see saw vibration... Well, I only posted what I did based on other peoples experience, guess that means I should do these things for myself to make sure.

Tripod collars are all very well and good in terms of transfering the load from camera to lens. Not a bad thing where a heavy lens is involved. They do, howerver, promote shutter and mirror induced vibration. The compromise is that while you are putting less strain on your camera body, you are going to have more problem with camera shake.
