摘要： A lens apparatus comprising an image pickup optical system having a focus lens, a focus state detection unit which detects focus state of the image pickup optical system, a distance detection unit which determines the distance to the subject, an actuator which drives the focus lens, a controller which controls the operation of the actuator according to the output from the focus state detection unit and a distance range setting unit which sets a distance range in focus operation for the focus lens, wherein the controller compares distance information from the distance detection unit and distance range set by the distance range setting unit to control the operation of the actuator which drives the focus lens based on the comparison results.
