ABSTRACT:
Camera apparatus of the type having an objective taking lens and an electronic flash movable between an erect operative position and a folded storage position is provided with a built-in, close-up lens arrangement for extending the focus range of the objective lens thus enabling a user to take pictures at nearer distances than would otherwise be possible using the camera objective lens alone. The close-up lens arrangement is structured for manual movement between a first position in which a close-up lens is in a storage location and a second position in which the close-up lens is captured and optically registered with the camera objective lens. The close-up lens can be released either manually or in response to movement of the electronic flash into its storage position. Upon release, the close-up lens automatically returns to its storage location.
