I've got the Canon t3i and i LOVE it for filming. As far as which camera to get, esp for filming, I don't think there's much of a video difference between the two cameras since they both have the flip screen and can shoot 1080p at 30 and 24 fps, and 720p at 60fps. That's about as deep as my knowledge goes between the two, but my best advice would be to go to a local CAMERA store and ask the reps. I went to mine and they literally knew everything about every camera, they should be able to hook you up too but it definitely helps to save a little money to get the extra stuff youll need, sd cards, mic, lens hood, and filters
hope this helps
