That's a good idea. What I do is just crank up the internal mics and with the 6k or 8k setup the camera so I don't have to worry about framing(i.e. with the 6k going to 1080p, frame it so it doesn't matter if the person moves around). Then I external record with a cmit 5u shotgun mic and earphones (really not paying attention to the camera at that point), then join it up in post (there's a bunch of new programs to basically join external audio with the scratch mics now). This way if the camera messes up in anyway I still have the audio (and put b-roll over the audio). Another thing I find is it's more important to pay attention to the audio and have the headphones on, then messing with the camera (if I don't have the headphones on and paying attention to that, the sound is almost always hopeless).
No, not at all. 90% of what I do these days is just color, plus some post supervision. If people ask for opinions on an internet forum, they're going to get them. Most of the time, when people ask questions like this they tend to ignore the obvious answer, which is hire a professional. My opinion is that the camera operator and DP already have enough headaches to worry about. Saddling them with sound on top of everything else is far too much work and will yield inferior results.
