Abstract: A method for focusing the shooting lens of a motion picture or video camera onto a moving or stationary object, which is imaged on a monitor of a display instrument is provided.

Abstract: A method for adjusting the picture definition on the camera lens of a motion picture camera. A drive unit is connected to the camera lens which is driven, in the manual focusing operation, by an picture definition handwheel of an operating unit, which displays the adjusted picture definition on a scale dial, and, in the automatic focusing operation, by an auto-focusing device for measuring the distance from an object to be recorded by the motion picture camera and outputting control signals to an electromechanical actuator, which is connected to the picture definition handwheel or to the scale dial of the operating unit, for adjusting or readjusting the picture definition adjusted on the picture definition handwheel or displayed on the scale dial as a function of the distance measured from the object to be recorded.

Abstract: A method for focusing the shooting lens of a motion picture or video camera onto a moving or stationary object, which is imaged on a monitor of a display instrument is provided. The solution according to the invention uses a distance measurement instrument which is aligned or tracked in relation to a predetermined alignment of the distance measurement instrument at the object as a function of the image angle of an imaging lens of the display instrument and the coordinates of the image of the object on the monitor of the display instrument. The horizontal and vertical angle deviations of the object from the camera are calculated from the coordinates of the image of the object on the monitor and delivered as setpoint values to the control instrument of an adjustment instrument holding the distance measurement instrument for aligning or tracking a measurement head of the distance measurement instrument.

Abstract: A film guide for a movie camera having an image window which is arranged in a recording beam path of the movie camera, a gripper platform which is supported on the image window, between whose mutually facing film planes a film channel is formed through which a movie film is moved by a film transport mechanism, and a spacing window which is connected to the gripper platform. The spacing window is supported on the image window in such a manner that the film channel narrows to form a film gap between the mutually facing film planes of the image window and the spacing window.
