ABSTRACT:
When the present position of a focus lens is on the closest distance side with respect to a predetermined position, the focus lens is driven and controlled using a TV-AF method without using the output result of an external ranging unit, and thereby a malfunction of an AF control due to parallax between an image pickup optical system and an external sensor is prevented.
