Abstract
Abstract A camera system includes a remote controller and a body of a camera. The remote controller is incorporated in a lens cap of the camera. A photographing magnification for an object is set by the remote controller. A taking lens of the camera is automatically driven to attain an in-focus position defined by a distance to the object and the magnification set by the remote controller. Thus, an image of a desired magnification can be photographed by remote control using the remote controller.
