Well, the red beats this thing handily and it can be had for under twenty grand.
The thing is that when you do video you don't get the full sensor. These cameras->video tricks do a sort of reverse interleaving. The chips themselves don't run more than 10fps. So the camera uses line 1 for frame 1, line 2 for frame 2, line 3 for frame 3, line 1 for frame 4, and so on. The practical upshot is that the 5k sensor gets knocked down to a thousand lines of resolution rather quickly. But then, because you're literally moving boundaries each frame, these weird aliasing artifacts appear. The quickest way to see them on the 5D is to take the camera and pan it right/left quickly, you'll see the image going all wavy. Some of the effect is the rolling shutter but it exposes the how the software is actually making the image.
So, you can't move the camera unless you're very very careful. You might as well shoot slates and sync audio in post as deal with the onboard stuff. The camera can't record longer than five minute takes because of a provision under Japanese export law that would make it officially a video camera. None of these problems are insurmountable but they're certainly there.
That being said, I have a friend who's planning on shooting a feature this fall on one of these things. I think he's crazy, but it's the crazy people who change the world.
