Re: 550D / T2i Overheating Issue. Solutions? Ok for documentary?

You can use an external audio recorder and input a line into the camera. This will give you a separate audio with better quality.

I wouldn't rely on this. If you are a professional, you need to step up and spend the cash. On the lower end Canon XH-A1, on the higher end Sony EX-1.

Buying a DSLR isn't really cost effective when you add up all the excessories, Lens, extra batteries, media cards. You'll need 2-3 lenses in your bag. Separate audio device, etc.
