Predictive Focus Tracking (Viewfinder Photography)
In AF-C mode or when continuous-servo autofocus is selected in AF-A
mode, the camera will initiate predictive focus tracking if the subject
moves toward or away from the camera while the shutter-release
button is pressed halfway.
This allows the camera to track focus while
attempting to predict where the subject will be when the shutter is
released.
