Interchangeable lens camera, and the lens unit, as well as the interchangeable lens camera of the camera body

摘要

In a camera body of an electronic camera, first information representing spectral characteristics of auxiliary light is read out of a nonvolatile memory under control of a CPU of the camera body. The first information is sent to a serial driver of a lens unit via a serial driver of the camera body. The lens unit includes a selector switch for changing a color signal to be inputted into an AE/AF detection circuit. In the lens unit, the first information is compared with second information representing spectral characteristics of the color signal which is changeable by the selector switch. On the basis of a comparison result, the selector switch is operated under control of a CPU of the lens unit such that the color signal having the spectral characteristics identical with the first information is inputted into the AE/AF detection circuit.
