Re: Canon 70-200, f4: clacking noise when shaking lens?

I know one more "test" won't make this a scientific study, but out of curiosity I just listened to mine. (f/4 IS version)

So I wouldn't be accused of abuse from shaking  I simply held mine vertical and slowly tilted it one way then the other. Inverted it and repeated the same.

There was a very slight sound/feel of some internal movement. Definitely not enough to be concerned, for me anyway. It operates smooth and takes sweet pictures so I'm not going to worry about it. Just thought I'd add my observation.
