ABSTRACT:
In a camera having a lens unit and a viewfinder, a power focus limiter is provided which is capable of narrowing the focusing range by using a driving motor. The device consists of an actuator, a motor control circuit, a driving motor and a detecting sensor, and a display device that provides a visual reference of the focusing range presently set to the operator. The system allows the focusing range to narrow quickly, while at the same time the operator can confirm whether the focusing range is in the desired range without moving his eye from the viewfinder.
