Remote Controller’s Remote Focus State

The focus product has one dial (focus control) that controls two separate parts of the camera: focal length and aperture. However it can only control one of these at any one time and is an absolute dial, meaning that a specific rotational position of the dial corresponds to a specific focal length or aperture.

This means that whenever the dial control mode is changed, the dial first has to be reset to the new mode’s previous dial position before the dial can be used to adjust the setting of the new mode.

Example workflow:

  1. Use dial to set an Aperture of f2.2
  2. Change dial control mode to focal length (set DJIRCRemoteFocusControlType)
  3. Use the dial to change the focal length
  4. Change dial control mode back to aperture
  5. Adjust dial back to f2.2
  6. Now the dial can be used to adjust the aperture.

  • YES if the focus control works. The control can be either changing the Aperture or Focal Length. If it is NO, follow the DJIRCRemoteFocusControlDirection to rotate the Remote Focus Device until it turns to YES again.

    BOOL isFocusControlWorks

  • Remote Focus Control Type

    Declaration

    Objective-C

    DJIRCRemoteFocusControlType controlType
