fi rst shot in continuous shooting.
Equal priority

Equal priority is given to focusing and continuous shooting speed. In low
light or with low-contrast subjects, continuous shooting speed may slow
down.
Shooting speed priority

Priority is given to the continuous shooting speed instead of achieving
focus.
Focus priority

Priority is given to achieving focus instead of the continuous shooting
speed. The picture will not be taken until focus is achieved.

become slower or the shooting interval may become irregular.

o
set, setting [Focus priority] may give better results.
