An optical apparatus which is mountable to a camera, comprising: a zoom lens optical element arranged within the optical apparatus; a focus lens optical element which is driven by a motor; a storage section which is adapted to store preset zoom control information including a predetermined speed and a predetermined driving position or a predetermined driving direction for the zoom lens optical element; a preset zoom control section (1 to 18) which is adapted to perform a preset zoom control operation for the zoom lens optical element by using the preset zoom control information, the preset zoom control operation being performed by driving the zoom lens optical element to the predetermined position at the predetermined driving speed or driving the zoom lens optical element in the predetermined driving direction at the predetermined driving speed; an auto focusing control section (6, 29 to 34) which is adapted to control an auto focusing operation for the focus lens optical element by generating a motor control signal based on a signal outputted from the camera and driving the motor by using the motor control signal; and a controller which is adapted to control the preset zoom control operation by the preset zoom control section and the auto focusing operation by the auto focusing control section, and said controller is further adapted to perform the auto focusing operation after the preset zoom control operation has been performed, when the zoom lens optical element is moved toward a telephoto end in the preset zoom control operation, and perform the auto focusing operation before the preset zoom control operation has been started, when the zoom lens optical element is moved toward a wide angle end in the preset zoom control operation. a zoom lens optical element arranged within the optical apparatus; a focus lens optical element which is driven by a motor; a storage section which is adapted to store preset zoom control information including a predetermined speed and a predetermined driving position or a predetermined driving direction for the zoom lens optical element; a preset zoom control section (1 to 18) which is adapted to perform a preset zoom control operation for the zoom lens optical element by using the preset zoom control information, the preset zoom control operation being performed by driving the zoom lens optical element to the predetermined position at the predetermined driving speed or driving the zoom lens optical element in the predetermined driving direction at the predetermined driving speed; an auto focusing control section (6, 29 to 34) which is adapted to control an auto focusing operation for the focus lens optical element by generating a motor control signal based on a signal outputted from the camera and driving the motor by using the motor control signal; and a controller which is adapted to control the preset zoom control operation by the preset zoom control section and the auto focusing operation by the auto focusing control section, and said controller is further adapted to perform the auto focusing operation after the preset zoom control operation has been performed, when the zoom lens optical element is moved toward a telephoto end in the preset zoom control operation, and perform the auto focusing operation before the preset zoom control operation has been started, when the zoom lens optical element is moved toward a wide angle end in the preset zoom control operation.
