Avengers: Age of Ultron cinematographer Ben Davis, who also shot Guardians of the Galaxy, used the Blackmagic Pocket Cinema Camera to get shots within the action sequences of the film.
We previously saw the Canon 5D Mark II show up as a crash-cam and POV camera on Captain America. The Pocket Cinema Camera doesn’t really come off as a surprise to work in tight spaces for action shots. It is smaller and cheaper than HDSLRs like the 5D Mark II. Additionally, it has an incredible 12-bit RAW image in a form-factor the size of a compact camera.
