Provided are a camera system, a camera, an interchangeable lens, and a compatibility determination method of a camera system capable of simply and quickly determining compatibility between the camera and the interchangeable lens. An eleventh contact (CC) provided in a camera () and an eleventh contact (LC) provided in an interchangeable lens () are composed of contacts in which an open drain output is possible. In a case where the camera () supports a specific function, the eleventh contact (CC) on a camera-side is set to a first polarity. In a case where the camera () does not support the specific function, the eleventh contact (CC) on the camera side is set to a second polarity. In a case where the interchangeable lens () supports the specific function, the eleventh contact (LC) on an interchangeable lens-side is set to the first polarity. In a case where the interchangeable lens () does not support the specific function, the eleventh contact (LC) on the interchangeable lens side is set to the second polarity. The eleventh contact (CC) on the camera side and the eleventh contact (LC) on the interchangeable lens side, which are mutually connected, are at the first polarity only in a case where both contacts are at the first polarity. Therefore, in a case where the polarities of the eleventh contact (CC) on the camera side and the eleventh contact (LC) on the interchangeable lens side are detected, it is possible to determine presence or absence of compatibility in both the camera () and the interchangeable lens ().

Provided are a camera system, a camera, a lens, an accessory, and an accessory detection method of a camera system capable of simply and quickly detect presence or absence of an attachment of the accessory and a type of the accessory. Data for accessory detection is transmitted from the lens to the camera. In a case where the accessory is attached between the lens and the camera, the accessory relays the data for accessory detection. At the time of relaying the data for accessory detection, the accessory adds own accessory information to update the data for accessory detection. The camera detects the presence or absence of the attachment of the accessory and the number of attachments of the accessory based on the received data for accessory detection. Further, in a case where the attachment is detected, the camera acquires information on the attached accessory.

Provided is an interchangeable lens digital camera that is capable of correcting a rolling shutter distortion in a live view image without delay in displaying the image. At the start of live view imaging, a lens controller in an interchangeable lens controls a shake detection sensor to detect the direction and amount of a shake, and produces deviation information on the basis of shake detection signals from the shake detection sensor, the deviation information indicating fluctuation in direction and amount of the shake for one frame of the live view image in the form of a parameter. The deviation information is transmitted to a body controller of a camera body through a serial communication unit, to correct the rolling shutter distortion on the basis of the deviation information.

A camera system, a camera body, and a communication method capable of satisfactorily acquiring lens information necessary for image processing or the like for a frame of a video from an interchangeable lens are provided. Three-wire serial communication is performed in which a request signal is transmitted to the interchangeable lens in synchronization with a synchronization signal (VSYNC) of an imaging element in a video recording mode, and a response signal is received from the interchangeable lens. In a communication mode in the video recording mode, the number of transmissions of a first request signal relating to acquisition of lens information such as a focus position, a diaphragm value, and a zoom position is limited. Accordingly, communication other than communication relating to acquisition of lens information can be performed in a period of one frame.

A finder device can be switched between the OVF mode and an EVF mode. A subject display area and an information display area are set in an EVFLCD. In the OVF mode, nothing is displayed in the subject display area of the EVFLCD, and an information image is displayed in the information display area. An EVF shutter is set such that the light transmittance of a first area, which corresponds to the subject display area, becomes a low transmittance and the light transmittance of a second area, which corresponds to the information display area, becomes a high transmittance. The first area, which is set at low transmittance, blocks light that leaks from the subject display area.
