What does a photographer do?

The lenses of movie cameras are all manual lenses, and there is no autofocus function. Focal staff helps photographers focus in real time through experience or distance measurement. What is more difficult is that when the person being photographed moves back and forth, the focus needs to follow this person all the time, and the focusing component needs to judge how far this person is from the camera in order to screw the focus of the lens to a proper position.
