Don't recall exactly how it does work (something about phase-shifting on the natural vibration) but the canon IS lenses work properly on the film EOS cameras, so that tech at least can't be dependent on holding steady on the sensor. Maybe there's something different in the Nikon / Olympus / otherguys approach.-- R.
