On a professional shoot, they'd handle it just like a conventional camera. record the sound separate using a slew of mics and HDD recorders.

I'd still record the audio to the camera though, as the editor can use this as temp material for the edit and as a sync guide.

The only way to fix issues with this type of audio would be to use a mix of expansion, de-essing and noise reduction/automation. It's almost not worth it though because it's already being processed and probably over-modulated by the onborad compressor. Also, by sheer convention, the distance from sound source will most often prevent a clean recording. Byt he time the editor levels the audio, room and ambiance will follow, to a degree that will void a professional sound.

If you're shy on a recorder, use a laptop and mbox. I've done this and it works fine. just use the camera audio as guide for sync.
