How specifically does it work? Is it that fluid lens controlled by an
electric field design? I can't imagine there would be a stepper motor with movable glass in those tiny camera modules. -- Alfred Molon ------------------------------ Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site

The lens moves. It just uses the same principle than in a CD/DVD: the glass is displaced by an acoustic coil, Like a loudspeaker.
