Since Magic Lantern is now supporting RAW on the 7D, I'm going to make an attempt to use my 7D as the A camera for interviews for the documentary I'm shooting about my daughter and her horse. I figure it will be a great opportunity to play with RAW workflow without having to spend a lot of money. The only thing I need to pick up is some super fast high capacity CF cards. They're fairly pricey, but they'll be a nice addition to my DSLR kit regardless.
I realize that the firmware for this capability is still beta and may be unstable, but using it on this project is fairly low risk.
I'll be shooting/posting some tests as soon as the cards come in.
