FX9 lens movement noise

[iatacs19]

Hi,


I just got an FX9 black and it's great. But, I have a question about the mechanical noise the lens makes when it moves. Is it supposed to make a motor-like noise? When it start up and comes out it makes a bzzz sound and same when Zooming wide and tele. It's not loud, but sounds like a scrolling-scratchy sound.
