  • Patent number: 8665360
    Abstract: 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.

  • Patent number: 8662767
    Abstract: A camera body includes a housing, an imaging element and a body mount. The body mount is fixed to the housing, and has a portion to which an adapter can be mounted. The body mount is disposed at a position away from the light receiving face of the imaging element by the amount of a flange back. A lens back of an interchangeable lens unit is longer than the flange back. The flange back is shorter than the length obtained by subtracting the adapter length, which is the length of the adapter in the optical axis direction, from the lens back.

  • Patent number: 8414205
    Abstract: An intermediate accessory enables a camera and an exchange lens to communicate with each other through an information processor configured to provide predetermined processing for information received from one of the camera and the exchange lens, and to transmit information that has undergone the predetermined processing, to the other of the camera and the exchange lens, while the camera and the exchange lens are being attached. The intermediate accessory obtains lens identification information from the exchange lens, which is used to identify the exchange lens. The intermediate accessory enables a camera and an exchange lens to communicate with each other without intervening the information processor and transfers to an operation restricting mode used to restrict at least part of an operation the intermediate accessory, when the lens identification information indicates a specific exchange lens that does not require the predetermined processing.
