Plastic lens mounts add to dust control problem

    If you use a lens with a plastic bayonet, run your finger (or a q-tip)
    around the rim of the lens mount. See that black stuff? That's fine,
    black powder created by abrasion from the metal camera lens mount,
    screw holes, etc, rubbing against the softer plastic lens mount each
    time the lens is taken on or off the camera. That powder can and will
    in-part end up on your sensor. This contrasts strongly with the far
    lower wear level of metal to metal lens mounting systems. In
    addition, the plastic powder is light and has a greater tendency to
    float around when the lens is removed.

    Are you sure you're rubbing your finger around the right circle?
