Are you asking how will the audio you record with SP-CMC-4U lapel style mics > R-07 compare to audio recorded with the camera mic of a $250 camera?
If that's the question, and assuming all other factors are equal (mainly location in venue), the answer is that the camera audio will likely NOT sound as good in comparison. For starters, the camera will probably record audio in a low-bit .ac3 format (probably 224 or 256 bit). Where as the audio recorded with the R-07 could be as high as 24 bit 4,608 kb/s at 96.0 kHz. Not to mention, the camera will record with an omni mic, while the SP-CMC-4U mics are directional cardiod mics.
