Hello to everyone, Actually i have just bought Sony HX5V camera and its really a great deal. But i have question, tht sometime when i movie camera speedily from dark light to bright light or bright light to dark light without zoom (1X) then sometimes sound comin from camera lens like "click" (i think its autofocusin) only at Camera mode, but its wont happen in Movie mode. and also its wont happen at night time. Is this normal?
