what mic were you using?

where was it placed relative to the sound source?

and what the hell do you expect from a $4or5k camera?

i don't think there's a pro around who expects 'serious' sound from its
on board audio, even when using, say a senn me66 or equiv. the frequency
it does an adequate, if not exceptional job with is that centred on
speech. recording anything serious would usually involve some off board
equipment, dat recorder, whathaveyou.

add to this the known quality difference between hdv and dv audio, and
you have your answer i think.

but hey, bloody great pics it takes, no?
