If you havent purchased the camera already, then its a complete no-brainer at the new price. You can spend the savings for the needed data acquisition pieces (ssds, ssd reader)
The original BMCC is more that capable of shooting a "feature" or any other format for broadcast. You will still need all the other "feature" film required goodies, such as lighting, audio, talent, etc..
I speak from experience, having used the camera for "shot for broadcast" tv commercials, and music videos. (I own and shoot with the BMCC EF )
The workflow was a little quirky at first (no remaining time on ssd displayed, no clip management, etc) but the camera has been a rock solid investment as far as picture quality is concerned.
Hope this helps, or was there something in particular you wanted answered?
