Abstract
A camera body in which, when a photographic lens is attached to the camera body, data exchange is carried out by communicating with the photographic lens via a plurality of contact pins electrically connected to each other. The camera body includes: a reset pin as one of the contact pins which outputs a reset signal and a reset release signal; an identifying pin as another of the contact pins for identifying an attached photographic lens; and an identifying device which identifies an attached photographic lens according to the change of electric potential of the identifying pin upon the output of the reset release signal to the reset pin.
