5D mk III - built in mic stereo or mono?
Being stereo or mono has nothing to do with whether the microphone(s) can handle high decibel input with less distortion...
Kind of like asking how the choice of lens affects the dynamic range of the sensor.
But, that being said, it sounds like the mike on the 5DIII is better than the one on the 5DII...
