Camera dillema need some suggestions
The sony nex 6 would be the best for videos. The extra money spent on the 5d mark II wont really help in that area. But have you considered a camcorder for videos?
Another thing I dont think it might be advisable to get two cameras. You could spend the money on lenses.
I want a more cinematic look and different lens options and you can't get that with a camcorder - camcorder is for home videos not short filmmaking.
