i use them both at the same time. 7D has better looking video. I would go 5d2 as well, or AF100. resolution is iffy on the HMC, and dont take me wrong, I love mine, it has made
me a lot of money. An EX1 wouldn't be bad either. You could buy a T21 and some fast primes for about 2K, then use the rest of your money for audio and lighting.
Thanks for the post. This question may not relate to the thread, but Would you rather use a 5d2 or AF100?
Also, thanks for suggesting the T2i with fast primes..
