G3 - Hear a low paper crackling sound

[RAJNEESHMISRA]

Hi All

I have purchased a new G3, am quite happy with the results but there is a strange sound I hear when I start the camera and the lens is protruding out. I can hear a low sound distinct from a lens zooming sound. It sounds like a paper crackling or something you hear when smoothing out a tin foil. It is low but I can hear it. Is it normal or do I have potential problem on hand?

Appreciate any help.

Thanks

Raj
