Canon 100MM f2.8 L IS USM Lens Loose or Elements Shifting Noise

[llehmann]

I recently picked up my Cannon 100mm Macro lens and heard a strange noise coming from inside. Sounds like the elements of something has come loose. When you give it a light shake... something doesn't sound right? 

I Googled the problem and found this video which shows the exact sound I am hearing from my lens.

Has anybody seen or heard of this? Does your lens sound like this? I never noticed the sound before?
Thanks

Hi, I have a the 100-400 is usm lens that has a very similar issue, noisy when slightly shaken when of camera and held vertical, i can see the inner lens components moving around, when connected to the camera and switched on the inner components do in fact "energise" and become centre, however when the camera is switched off the inner components "fall" to the side of the main lens body and "rattle" when slight movement is applied. Surely this cannot be right and will eventually damage the lens?? Does anyone else have a similar issue the this model of lens or is my lens faulty??
