I've been playing around with the V1 and notice that whenever I jar the camera up and down there is a light "clunk" sound from inside of the camera. This same sound happens whenever the camera is turned off. This happens with both of my V1 cameras so I can only assume this is normal.

Does anyone know what this sound is coming from? The lens maybe?

I am going to assume this is the same things we experience with the DVX100's.

It is the gyro stabilizer 'thingy' and nothing to stress about. When you turn the camera on, it stops doing it, right ? That is because it is now actively spinning.

Assuming of course.
