I'm looking for a Camera Mic to do low budget tech videos in place of the dredded in camera mic. I'll be using it both indoors and out, probably no farther than 15-20 ft. distance. Budget is $75, camera being used is a Cannon ZR930, I'm not worried about mounting. Here is the microphone I'm thinking of getting this one:
Does anyone have a better recommendation for less than $75? Also I plan to periodically use a 3.5mm extension to position the mic away from the camera, about how long can the extension be without causing too much noise in the line?
