Zoom noise in video mode on Sony Rx100

Hi,

I just got the Rx100 on Saturday and have been playing with it all day yesterday and today.. However i found something interesting in video mode .. When zooming while shooting a video , the zoom ring noise is captured very clearly in the video in quiet scenes .. It is really clear when you play back on TV .. That is such a bummer for otherwise good camera .. So is this normal or something wrong with my unit .. I doubt it as i think Mics are so close to the zoom lens they wil capture any sound near or close ..

PS : I had enable wind reduction on. Maybe i should turn it on

Any thoughts
