Patent number: 8665360Abstract: 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.Type: GrantFiled: January 31, 2013Date of Patent: March 4, 2014Assignee: Panasonic CorporationInventors: Dai Shintani, Kenichi Honjo, Norikazu Katsuyama
