1. A way locking all settings but the trigger and AF point joystick and such so one still can shoot with it and it uses the settings as they where before locking. (Perhaps the movie button could be set to do that as a toggle).
2. Focus Stacking, the hardware are there, just a "few" lines of code to make it happen.
3. Movement trigger. Hardware etc are there (when focus is achieved by something moving into the frame and the focus system decide it's in focus take the shoot (Manual AF, just waiting for something moving into focus). Just a "few" lines of code to make it happen.
