Hi there!

I bought the Lumix TZ3 before Xmas and boy am I a happy photographer..? It is much better than a couple of digital compacts I have worked with in the past!
Having said that I have come across something that may become a future problem and I would like your input on that.
I noticed that the camera emits two kinds of sound from its body while on any dial position (apart from playback and clipboard).
One is a continuous electronic "nnnnnnn"
And the other sounds more like a mechanical whirling.
Both of them are faint and you have to bring the camera close to the ear in order to hear them.
Is this something common or should I get anxious. It is a brand new camera!
Thanx for reading and Happy new year to all..!
