EOS R8 or Canon EF 70-200mm? Screen shakes and loud noise

[zabdiel]

Happens whenever I turn on my camera, and use said lens (ef 70-200mm is ii). Screen shakes and a loud noise emits (from either the camera or lens, I'm not sure). But when I use another lens, like my ef 50mm 1.8, I have no issues.

Is there a question? One or the other needs servicing.

Specifically, when the Canon EF 70-200mm lens is attached, the camera screen shakes and emits a loud noise, though other lenses work without problems. Another user, "ebiggs1," suggested that either the camera or the lens may require servicing.
