Abstract
A camera for use with interchangeable lens barrels that can be attached to and detached from the camera body has a drive mechanism that provides the generating source for the drive power of drive elements inside each lens barrel built into the camera body. The connecting structure that provides a connection between the camera body and lens barrels varies according to the type of lens barrel, for example, whether the lens barrel contains a fixed focal length lens or a variable focal length lens. So, the functions realized by the drive of the drive elements from the drive mechanism vary according to the type of lens barrel.
