I used 5DII/ML as main studio camera (handheld b-cam was iPhone 7 Plus running 24FPS app) and you can spot the 5D/ML b-roll mixed in throughout. This rig was intended for my Canon/ML but because the monitor shipped with a micro-HDMI I couldn't use it with the 5DII, and substituted my Sony a5100 for the beach reel in the middle. I'm looking to add a EOS M to the mix and will shoot another version of this using that.

Nice work! Can you describe the creation and setup process in the camera a little more detail?
