Abstract: In a remote controllable camera system having a remote controller, a camera body provides with calculation means for calculating an angle between the remote controller and an optical axis of a photo-taking lens and moving means for moving the optical axis to a point where the angle is a predetermined value. Furthermore, the camera body provides with judging means for judging whether or not the remote controller is within the field of view of the photo-taking lens and displaying means for displaying the judging result of the judging means.

Abstract: A camera having zoom lenses of a photographing optical system, zoom lenses of a viewfinder optical system, and a driving motor for driving both zoom lenses. A transmitting mechanism for transmitting the force of the driving motor to the zoom lenses of the viewfinder optical system having a gear train connected to the driving motor and a rotation cam which is provided coaxially with the last gear of the gear train to drive the zoom lenses of the viewfinder lens. A key projects from the end of the periphery of a rotation shaft included in the cam. The last gear is mounted around an end of the rotation shaft of the cam and has a key groove engaging the key. A play is provided between the key groove and the key.

Abstract: A camera having a photographic optical system capable of switching over a focal length having a control member, a cam operatively connected with the control member, a first cam face defined on the cam for effecting a focus adjustment in a first focal length, a second cam face defined on the cam for switching over from the first focal length to a second focal length, a third cam face defined on the cam for effecting a focus adjustment in the second focal length and a cam follower driven by the first through third cam faces and connected with the photographic optical system to drive the same. The second cam face is aligned in an operative direction of the cam or peripherally relative to the first cam face and the third cam face is aligned in the operative direction of the cam or peripherally relative to the second cam face.
