Lens to body attachment problem

[Livin The Dream]

Whilst out shooting xmas day for the first time with my new 5D body and 70-200 mkII I noticed a bit of slipping between body and lens. It's more noticeable because of the size of the lens. Instead of a positive solid lock it's possible to rotate it slightly. All other lenses are ok and this lens was ok on my 50d, is there something I can do or best to send it to Elstree?

Do nothing. As long as the lens doesn't twist off then don't worry.

My L lenses have a little movement when attached, it does no harm and doesn't affect anything with the camera. If the movement is only a small rotational movement then there's nothing wrong.
