loud, you will need some sort of manual audio control. Without manual audio control, you will be relying on the camera's auto audio gain. When the audio is loud, there is a high risk that the auto audio gain will be overwhelmed resulting in very muddy audio being recorded. Also, when REALLY loud, it will "peak" resulting in static being recorded. These audio recording problems cannot be fixed later.

Some low-end Sony and Canon camcorders have a simple "normal" or loud audio toggle in the menu. MicRefLevel or Mic Attenuator, respectively. Better camcorders have a 12-14 step manual audio gain control and prosumer and above have a thumbwheel control.

I do not believe any of the cameras on your short list have any sort of manual audio control.

You could also pick whichever camera or camcorder you want and get the audio with an external "audio field recorder" with manual audio control. Zoom, M-Audio, Edirol, Tascam and many others make these. As was pointed out to me a few weeks ago, Zoom has one - with a camera included (though small lens and imaging chip likely will result in poor low light behavior for video recording.
