Camera body and interchangeable lens |
摘要 |
A camera body at which an interchangeable lens, holding a plurality of sets of optical characteristics data, each expressing specific optical characteristics in one of a plurality of representation formats, can be detachably mounted, includes: an identification information reception unit that receives lens-side identification information from the interchangeable lens, which indicates the plurality of representation formats; an identification information storage unit in which body-side identification information indicating each representation format that the camera body is capable of recognizing among the plurality of representation formats, is stored; a selection unit that selects a single representation format included in both the lens-side and the body-side identification information, among the plurality of representation formats; a request unit that issues a request to the interchangeable lens for the optical characteristics data corresponding to the selected representation format; and an optical characteristics reception unit that receives the requested optical characteristics data from the interchangeable lens. |

1. A camera body configured to detachably mount an interchangeable lens holding a plurality of sets of optical characteristics data, each of the plurality of sets of optical characteristics data expressing specific optical characteristics in one of a plurality of representation formats, the camera body comprising:
an identification information reception unit that receives lens-side identification information that originates from the interchangeable lens, the lens-side identification information indicating the plurality of representation formats; an identification information storage unit in which body-side identification information is stored, the body-side identification information indicating each representation format that the camera body recognizes among the plurality of representation formats; a selection unit that selects a single representation format that is included in both the lens-side identification information and the body-side identification information, among the plurality of representation formats; a request unit that issues a request to the interchangeable lens for the optical characteristics data corresponding to the selected representation format; and an optical characteristics reception unit that receives the requested optical characteristics data from the interchangeable lens. |
