My video setup for the Canon 7D and Zoom H4n Field Recorder
 

This is the video setup I have:

For those unfamiliar, the Zoom H4n is a field recorder not an external mic. Under normal use, you need to slate the audio and then sync it in post processing.

I have connected the H4n directly to the 7D via the headphone out. This way I avoid having to sync the audio later. With this setup, I have the option of treating the H4n as an external mic, or if audio quality is important or I'm required to be far from the sound source, I can also place the H4n next to the sound source and sync later.

I have a connection to my iPhone emitting a 20Hz tone because magic lantern isn't available yet for the 7D. The 20Hz tone will suppress the AGC but the frequency is low enough that it is not audible (unless you have amazing hearing).

Questions?

Crazy! What do you use this set-up for? I was going to get a simple mic like this:

Yea, it does look a bit crazy ;)

After reading various forums and reviews, the Zoom H4n appeared to be the best audio solution. I got the Zoom H4n because of its versatility and good microphone. The setup is more complicated and a bit more time to set up but it's worth it. Not only can I use it on or off camera, it also allows 4 simultaneous inputs. So for instance, if I am recording a live band event, I can have the built-in mic on the Zoom to record ambient sound, while simultaneously I can plug the recorder directly into the soundboard to record the music.

Hmmm.....gonna have to go to ProVision for more advice...

Very nice. I am impressed. I'm just lazy and won't probably use my 7D for much Video. I have the JVC Everio for that!
