I've got a shoot coming up where I'll be capturing various outdoor montage scenes. A character riding a bike through the city, walking on a sidewalk, etc. No dialogue. The audio I'll need for these shots isn't particularly important, but from time to time it's nice to get decent scratch audio to mix into the background while music is playing over the montage. The internal MIC is pretty okay for this I guess, but it tends to sound a bit more "hollow" and doesn't always mix well with the audio I get from my other MICS (I use an NTG-3 for outdoor dialogue booming and Audix hyper for my indoor dialogue.) I guess what I'm looking for here is an easy, decent camera-mountable shotgun (or other type of MIC) that will work decently well. Any suggestions from other C100 users?
