A system for performance of photographing with moving picture cameras, still picture cameras or television cameras, particularly of direct sound - movie picture photography, whereby a signal receptor - and/or transmitting - device is coordinated to each photographic object, and the running time between the photographic object, and respectively, between the signal receptor - and/or transmitting - device and the camera is used for determining the distance of the photographic object from the camera and under the circumstances for the automatic distance setting of its camera taking lens. A delay device is provided for the running time signal, the delay time of which is adjustable by means of a handle, whereby in the sense of a delay time shorter then a predetermined delay time the focal plane of the camera taking lens is adjustable particularly continuously in front of the receptor - and/or transmitting device, and in the sense of a longer delay time than the predetermined delay time the focal plane of the camera taking lens is adjustable particularly continuously behind the signal receptor - and/or transmitting - device. |
