Do you think of implementing Bluetooth into Axiom?
Well there is a new Crowdfunding campaign for a new controller: https://www.indiegogo.com/projects/flow-an-intuitive-precise-wireless-controller
It is open source and Linux based and could be a perfect camera control unit.
Think of just using this small wireless bluetooth device as folow focus, iris and iso controller, start / stop gestures, and even more...
And you could attached it easily to your tripod head or quickly to a handle if shooting handheld.
There would be so many controlling possibilities for the Axiom camera.
