摘要： A camera system includes an interchangeable lens and a camera body. The interchangeable lens has a focal adjuster including a focus lens group, an absolute position detector configured to detect the position of the focus lens group with respect to a movable range, and a relative position detector configured to detect the movement amount of the focus lens group. The camera body has a first focal detector configured to detect the focal state on the basis of a contrast value and a second focal detector configured to detect the focal state by phase difference detection method on the basis of the optical image. When the first focal detector is used for focal adjustment, a detection of the focal state is performed on the basis of only the information obtained by the relative position detector.

摘要： A lens barrel includes a focusing lens, a driver, and a controller. The focusing lens changes a state of focus by moving in the direction of an optical axis. The focusing lens is subject to a load which is dependent upon the position of the focusing lens along the optical axis. The driver is coupled to the focusing lens and produces a driving force to move the focusing lens along the optical axis at a predetermined speed. The controller is coupled to the driver to adjust the driving speed of the driver relative to the position of the focusing lens.
