Abstract
A camera control unit obtains information related to an optical correction of an interchangeable lens from an intermediate accessory by a second communication via a second communication path. The camera control unit controls a communication in a manner that the above-described information is used for the optical correction of the interchangeable lens.
Claims16
An imaging apparatus to which an interchangeable lens and an intermediate accessory, which is attachable between the interchangeable lens and the imaging apparatus, are attachable, the imaging apparatus comprising:
- first communication terminals configured to communicate with the interchangeable lens;
- second communication terminals configured to communicate with the intermediate accessory;
- and
- a communication control unit configured to obtain information related to a method for a correction and information related to a parameter for correction via one of the second communication terminals and to receive lens information to be corrected via one of the first communication terminals.
An intermediate accessory which is attachable between an imaging apparatus and an interchangeable lens, the intermediate accessory comprising:
- first communication terminals through which information communicated between the imaging apparatus and the interchangeable lens passes;
- second communication terminals configured to communicate with the imaging apparatus;
- and
- a communication control unit configured to transmit, via one of the second communication terminals, information related to a method for a correction of optical information of the interchangeable lens and information related to a parameter for the correction of the optical information,
- wherein lens information to be corrected transmitted from a lens apparatus pass through one of the first communication terminals.
A control method for an imaging apparatus to which an interchangeable lens and an intermediate accessory, which is attachable between the interchangeable lens and the imaging apparatus, are attachable, and which includes first communication terminals configured to communicate with the interchangeable lens, and includes second communication terminals configured to communicate with the intermediate accessory, the control method comprising:
- obtaining information related to a method for a correction and information related to a parameter for correction via one of the second communication terminals;
- and
- receiving lens information to be corrected via one of the first communication terminals.
A control method for an intermediate accessory which is attachable between an imaging apparatus and an interchangeable lens and includes first communication terminals through which information communicated between the imaging apparatus and the interchangeable lens passes, and includes second communication terminals configured to communicate with the imaging apparatus the control method comprising:
- transmitting, via one of the second communication terminals, information related to a method for a correction of optical information of the interchangeable lens and information related to a parameter for the correction of the optical information;
- and
- causing lens information to be corrected transmitted from a lens apparatus to pass through one of the first communication terminals.
