my boss got this HMC150 from Panasonic recently - it is brand new - never even been tested. as you hold the camera on the top handle and tilt it back and forth at 45 degree angles there is some clicking noise coming from within the camera body it seems. tilt it up, titlt it down and not to fast or hard even. it sounds like something is loose in there, a very soft clickcing, almost like a can of guiness or a spray paint can. it is toward the lens - seems to be around the zoom thing. it is like a plastic flap is tapping against other plastic. anyone have idea of this?
