摘要： A lens barrel comprises a first zoom/focus lens group and a second zoom/focus lens group configured to respectively vary a focal distance and imaging distance by moving in an optical axis, a first actuator configured to drive the first zoom/focus lens group, a second actuator configured to drive the second zoom/focus lens group, and a drive controller configured to independently control the first actuator and the second actuator. The drive controller is configured to wobble the first zoom/focus lens group by reciprocating only the first zoom/focus lens group out of the first and second zoom/focus lens groups in a optical axis direction.

摘要： An image pickup apparatus of the present invention is an image pickup apparatus including an ultrasonic motor 35 that moves a focus lens 24, and further including a correction control part 100 that operates the ultrasonic motor 35 under a predetermined condition. The correction control part 100 is capable of executing a correction process by measuring a frequency characteristic of an applied voltage at the time of operating the ultrasonic motor 35 at a predetermined rotation speed, comparing the frequency characteristic with a preset reference frequency characteristic, and correcting the frequency characteristics on the basis of a difference between the frequency characteristic and the reference frequency characteristic so as to calculate a correction frequency characteristic. Accordingly, even when the frequency characteristic of the ultrasonic motor varies due to wear of the ultrasonic motor and mechanical components coupled thereto, a stable drive can be maintained over a long time.

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 camera system includes an interchangeable lens and a camera body to which the interchangeable lens can be mounted, either directly or via an adapter. A lens microcomputer of the interchangeable lens is configured to hold lens information including information related to a focal point detection method. A body microcomputer of the camera body is configured to select a focal point detection method on the basis of lens information. The body microcomputer is configured to select a contrast detection method as the focal point detection method if the interchangeable lens is compatible with a contrast detection method. The body microcomputer is configured to select a phase difference detection method as the focal point detection method if the interchangeable lens is not compatible with a contrast detection method, and the adapter is compatible with a phase difference detection method.
