I just got my FS100 - Love It!

One thing that's a bit annoying, though is there is a silver colored band / ring right at the front of the lens mount. Mine is loose around, and it just rattles when I move the camcorder, or touch it. Does your ring rattle as well? Unless I'm really moving the camcorder around it's fine, but, just wondering if this is normal or not, and if so, does it bother you?

Have you tightened the screws or is this a different part you are referring too?

No rattle here. For the price you paid for the camera I would call or email Sony right away.
