Cine camera with film transport speed adjustments - has devices to match drive motor rotational velocity to shutter motion ion characteristics

摘要

A cine type camera having a drive motor which can be set to various film speeds during filming and having a photoelectrically controlled regulator for the objective diaphragm and a device operated by a switching type hand grip which automatically matches the setting of the diaphragm to the selected film velocity by adjusting the current or voltage in the measuring circuit of the diaphragm control, has devices which match the alteration of the rotational speed of the drive motor (2) to the shutter control (34) motion characteristics on change of film running speed.
