Yesterday my RF 70-200 f/2.8 arrived. When I took it from the box, I found it made rattling sound when I gently shook it. Looks like the floating lens element for IS are movable even when it's disconnected from the camera.

I know some rather old lenses with IS do make rattling noise when being shaken, but I'm not sure this is true on this newly released lens.

So for anyone who also have this lens, is this reproducible on your copy? I'd appreciate if you can tell me.

BTW, I haven't put it on my camera because my EOS R is still on its way.

I just checked mine. In the closed position I did not notice any rattling at all. I didn't vigorously shake it but did move it up and down as well as flipping it over a few times.

However, I usually remember to turn off my camera before removing the lens so it was probably shut down correctly. You might want to put the lens in the camera and make sure it's functioning and then turn it off and remove it to see if that changes things.

I just shook mine. It does make some noise and you can see the floating IS element wobble around. I tried to shake it really hard (like while running with the lens in a backpack) and the noises stay the same. Doesn't sound alarming to me. It must be designed to do this and last for decades. When I turn the camera on the sound and movement is less as the IS unit is powered.
