Videos & Movies on Canon qestion
There is the "Digital Video Talk" here. Also, http://cinema5d.com/ is quite popular. The Canon 5DII has been used in "House" "24" and to shoot B roll stuff for regular cinema.
Video on the 5DII is spectacular, but I use a Zacuto viewfinder, Rhodes mic and shoulder rig as a minimum setup. You also need a powerful computer to process those hefty HD videos. Just a heads up.
Interestingly, Photoshop CS6 has video-handling capabilities, which is kinda cool.
