100-500 lens issue

[Hali]

Well I guess I get to send something else to Canon Repair. Lets see how it goes this time.
I took the 100-500 out to shoot surfers and the surf today, when I got home and went to clean the lens I noticed that the lens itself is wiggling inside the casing. I have never dropped the lens so I don't know what happened, this is the second lens I've had this problem with.
Has anyone else had a problem with it?

Wish me luck.

The Secret of the Broken Element: A Canon RF 100-500mm f4.7-7.1 Teardown

... you're not talking about the image stabilization wiggle, are you? All Canon lenses with IS have a moving element.

That was a heck of an article. It takes some serious nerve to pull something like that apart (I would have liked to have seen if they could put it back together.

No, this goes beyond the IS wiggle. The IS wiggle is a little movement, this was the whole inside of the lens moving around and making a noise.
