I am looking at improving the audio that I get from my videos on my 7D: the wind and camera vibration on the audio is terrible. I see from other threads that a couple of people use Røde videomic pros, but I was wondering whether anyone uses the pro stereo version. I am tempted by the thought of better ambient sound from this mic but am worried that it will collect too much general noise (particularly from birders standing nearby) to be useful. Any advice or opinions gratefully received.
