There are scan backs for large format digital which can be had for not too much. But they need a view camera, and can't really be used for anything but landscapes (or very slow moving people; maybe sloths).
Cool, you're a Canon shooter. I've just got a lowly 30D, but I'm not a pro. Although, I have made enough money here and there to break about even on my kit.
I was thinking about finding a way to get a 5D MKII, so I could mess with the video side of things too. But it really is a picture camera which shoots video. If I do try my hand a digital video, I think I'll pick up a Red Scarlet, which is a video camera which can also shoot stills.
