I knew about the 24fps, but not about the 60fps. That's awesome. Now If only firmwares were a little bit easier to synchronise with the camera.
I never done any on my cameras and I should do it for my D300. I sometimes get banding problem that is fixed with the first firmware released. It's probably easier than I thought, just never get through all the steps. Still I'm exited to see a video taken at 60fps with the 5D MarkII
