Ahhh, yes but does it drop just previous to making an exposure? I just looked and it does not ... so that is good. It would indicate that using live view is a more vibration free method of making the photograph. But the shutter still has to close and then open again ... probably not of great consequence ... I wonder now how much difference there is between live view release and mirror up tripping. Or using a 2 second delay. Should do some rigorous testing some day.
