What I have found is on some larger zooms that if you remove the lens from the body while power is on, you can get a rattle. SO turn off the camera before removing the lens.

Of course I know this. But the point is that I found the problem before I got the body.

Yesterday my EOS R arrived. To make sure that this problem is not caused by improperly shutdown in the factory. I put it on my camera, turned on the camera, took some photos, shut down the camera. The problem persists.

One more small point you have to wait at least 5-6 sec after you turn off the camera to dismount the lens. The R keeps the IS on for 5 sec after you turn it off.

I did wait.

I just made contact with a local authorized store of Canon. They tried this on their sample copies and the problem also exists. The problem is reproducible when you hold the lens vertically with the front element facing up then gently shake the lens. But when it's placed horizontally, being gentle shake won't make any sound.
