Interchangeable lens and camera body |
| abstract |
PROBLEM TO BE SOLVED: To provide an interchangeable lens capable of accurately adjusting a focus. An interchangeable lens 3 attached to a camera body 2, the optical system including a focus adjustment lens 33, a drive unit 331 for driving the focus adjustment lens 33 in the optical axis direction of the optical system, and a focus adjustment lens. The focus adjustment lens detected by the detection unit 332 that detects the position and the image plane movement coefficient that changes depending on the position of the focus adjustment lens and corresponds to the movement amount of the image plane with respect to the movement amount of the focus adjustment lens. The first value, which is the image plane movement coefficient at the position, and the image plane movement coefficient that minimizes the amount of movement of the image plane with respect to the amount of movement of the focus adjustment lens within the drive range of the focus adjustment lens by the drive unit. And a transmitting unit that transmits the second value to the camera body, the transmitting unit repeatedly transmitting the first value and the second value to the camera body.
