I have the s570 and it sounds like a fan in the background -.- I'm going to return it and get the sony one ! gawd ppl say that nikons are amazing but I can't record anything without it sounding like there's a stupid fan behind me
the cause of this, is because of the lens of the camera, not really the les, but when you are moving, the camera is estabilizing image, so it make noise.
:( yeah mine L11 do the same, it have video size 640x480 * and video q is normal but that fck noise :( maybe i can replace that mic with other but nothing i allready broke display :D
