Further to our discussions about sound, I saw a Zoom H4N audio recorder in action on a Canon 5D Mk2 shoot a couple of weeks ago, and I'm going to get one for myself.
It's a portable audio recorder with XLR inputs and on board mics. There's a video about using it with DSLRs here (including mounting it on your camera), which is part infomercial for Zoom, part infomercial for Zacuto, but still has a lot of interesting stuff in it. http://vimeo.com/4782593 Rupert http://twittervlog.tv
