I guarantee the 1D-C will be a flop. I work in video and TV, and people are pretty bummed about it, especially since it's $15K.
Canon video is going to lose their shirts, and Sony is going to capitalize big time.
I used to work in academic science. My lab mates and I would go to a scientific meeting, see the latest golliwog instrument, and say wow that's great, but no one will ever buy that, it costs way too much. Now I work in pharma, and I have a multimillion dollar annual capital budget - what was insanely overpriced before is now quite affordable. Point is, Canon seems to be targeting big-budget studios and filmmakers with their recent cinema releases (note: they call it the Cinema EOS line, not
the 'video' line), and not indie filmmakers. Canon's goal isn't to please everyone, it's to turn a profit. If the quality is high, just as I have no problem spending $1MM on a piece of scientific instrumentation, major studios will have no problem spending $15K on a camera. Heck, buy ten, they're cheap. Probably not a flop, again, provided it delivers on quality.
