I rented a couple of cameras and lenses to see which one I'd buy and made this video. I haven't worked with DSLR footage before so I don't know how to get rid of the rolling pixels/blocky digital stuff. I ended up buying the 7D in case you were wondering. :)

Here are the specs:

Canon 5DmarkII
Canon 7D
24-70mm f 2.8L USM
70-200mm f2.8 IS MKII
Edited in Premiere Pro CS5
Colored in After Effects- Synthetic Aperature's Color Finesse
