I'm just getting into film making, and obviously sound on my T2i will not suffice to my needs. I am on a low budget. My friend who works with an indie group suggested getting a clip on mic, and using that for now, and then later add another one. I was looking at a shotgun mic. What method do you suggest? and what equipment should I look at new/used for under $100? I also need money for a rig. Please excuse any dumb comments ignorance I might have let slip..
