ABSTRACT:
An electronic still camera is comprised of a zoom lens for magnifying an incident optical image, a focusing lens for focusing the incident optical image, a motor for driving the focusing lens, a photo-electric converting unit for converting the optical image incident thereon through the zoom lens and the focusing lens into an electrical signal, a focus detecting circuit for detecting the focused state of the incident optical image, and a zoom lens state detecting circuit for detecting the state of the zoom lens, wherein when the movement of the zoom lens is detected by the zoom lens state detecting circuit, the focusing lens is moved by the motor so as to focus the incident optical image on the basis of the detected result of the focus detecting circuit.
