"Induce"? It's the camera that induces the vibrations. The support system may
enhance/exacerbate or tend to absorb/damp,
but it doesn't start it. (Except for wind, which has nothing to do with the QR
plate.)

Really? I just pulled down the 3047 head to check. I can try to move, tap, play
with the plate any old way, and it acts
like it's welded to the head. I've used that head on the 3236 legs with all
kinds of body lens combos for the sorts of
moderately long exposures where camera induced vibration is a problem and never
seen a sign if it.

I generally agree. Although in the case of my non-QR version of the Manfrotto
monopod head and of the Velbon PH-253 ball
head, the big thumb wheels make them very quick and easy, without the extra
weight of the QR stuff.
