Description
When the distance to the subject changes abruptly, the
camera waits for the specified period (long, normal, or
short) before adjusting the distance to the subject. This
prevents the camera from refocusing when the subject is
briefly obscured by objects passing through the frame.
The camera immediately adjusts focus when the distance to
the subject changes. Use when photographing a series of
subjects at varying distances in quick succession.
