Default Rattling sounds on startup?

I've noticed that when the FZ10 starts up and the lens is extended, there is some kinda rattling sound, like the motor is stuck or something. Is this normal?

I would call the 'normal' sound of the lens extending in or out as more of a whirr. Not a rattle. If you really feel it's a "rattle", can you bring it to a store (or just drop by a store) that has an FZ10 and compare the sound?

No, it shouldn't rattle, but the "turn on" noise is much louder than when you zoom in and out.

there is more of a heavy vibration upon lens extension on startup. I checked 3 pieces in Ritz and all were like that.

What you are hearing is a combination of two things - both are normal.

1. The large lens body tends to amplify the mechanical noise from the internal gear drive.

2. The OIS lens element is suspended by two magnetic coils. At startup the coils are not yet energized so the element has some mechanical movement.

Item 2 is the same on the FZ1 though you don't hear it as much due to the smaller body.

Nothing to worry about.

more than that, bob, I think panasonic, in its jest for a quick startup, provided a quicker extension speed, which invariably leads to a vibrating sliding motion. If it were a tad slower, it would not make this brrr....bzzz sounds upon startup

SHHHH! Bob's going to record that as a complaint, and the next model will end up with a slower startup!

You're absolutely correct (on the faster speed)!
Early in the testing I spent an afternoon comparing the "noise" from several pieces. The issue comes up from time to time but the reliability appears solid. I see no need to worry.
Thanks guys!

from an engineering stand point, I can say that it is as harmful as second hand smoke. It will affect you, but it will be long before you even notice the results. By that time, I am pretty sure most of the owners will have moved up to some other digi-cam.

How will it affect us? The drive mechanism is operating well within the design specs. An audible sound is not necessarily negative. Actually, after having disassembled the lens about a dozens time the design is very simple with far fewer moving parts than you might imagine. I'd be interesting in hearing your thoughts on this.
Thanks!
