Canon EOS5DmkII, One night in Beijing. from Dan Chung on Vimeo.
Guardian photographer Dan Chung has posted a video shot on the Canon 5D MkII. Dan, a recent convert to Nikon bought the 5D MkII to use as a video camera and the clip above was shot using Nikon and Contax lenses with an adapter using manual focus. If you register on Vimeo, it will allow you to download a mid res 720p version of the video.
There's a forum thread on this video on the DVi forums.
I should hopefully be getting a review unit of the camera soon, so stay posted!
