I just received the camera (HMC 150) yesterday. When the camera is off and I tilt it forward and backward I am noticing a sort of internal knocking noise coming from the front area of the camera. However once I power up, the noise goes away. Everything it tight.

Can someone please check their camera and let me know if you are hearing this as well?

thanks.

**Update: I just read that this is the OIS and it is common?

**Update 2: Panasonic makes reference to this in the Manual. It's lens movement and it is normal.
