It’s faster to build a sistem where you focus manually to do reference to phone that using a full auto system with database. You need to build a perfect database of all data’s, and enable to calibrate it be cause some lenses are not perfectly aligned to marker of distance, some lenses suffer of backfocus.

It’s not a standard space, unfortunately. Some lens focus in clockwise direction some other opposite, some lenses have a long run some other small run to do focus. It’s a trivia write a code to found focus with phone lens, but to edit focus lenses you need to know what kind of lenses is connected. Without having to write code for the camera. Inviato dal mio iPhone utilizzando Tapatalkīut that's exactly what I am saying, it would be trivial to write an app that controls a wireless focus system like the title nucleus to give a cinema camera autofocus.

Anyway ask to yourself why only few photocameras with excellent autofocus on photo, not have autofocus or continuos focus on video? Simple answer is that is not simple to do. You forget that phone Os is more complex and sofisticate than a cinema camera. My iPhone has all the hardware and software needed via APIs to take care of autofocus and tracking without having to re-invent the wheel.
