It was recently suggested by Bill Putnam, a photojournalist, that a solution to the problem of photographing and recording audio at the same time would be to use a Light Wave Mini Mount. Rather than switching his camera for his audio recorder and vice-versa to do so, he attaches the Light Wave Mini Mount to the camera's flash shoe for his microphone and does both. He uses a mono microphone with a narrow sound cone.
The downside to this system is that the microphone will catch the sound of the shutter, and possibly one's breathing...but it's an idea to be considered. I suppose it would be workable for ambient sound, by editing the shutter noise out...but that would not work for interviews.The other downside is that the mount is quite pricey at $165.
