Abstract

A film camera is disclosed which is equipped with a device for recording synchronizing data, for use in automated post processing, wherein, for example, timing data is exposed onto the film by means of an optical display element activated by an activator unit and with a rotary shutter positioned so that at a first half rotation of the shutter the light entering through the camera objective is deflected through the viewfinder and during the second half rotation of the shutter the light enters an image window and wherein the activator unit comprises a shutter drive which controls the actuation of the shutter over which the rotating shutter is held in an arrested position covering the image window during exposure of the film by the optical display element.
