Active lens components are provided for transmitting to a corresponding photographic camera information from a photographic field lens which is transformed into electrical signals. These components transform the information into electrical signals, the properties of which are convertible. The signals are transmitted to an evaluating circuit in the camera either serially via a contacting device or according to a predetermined chronological sequence. The evaluation circuit is provided with means by which the original information is gained back from the signals. The signals resulting from the recovery are fed to display means and/or to control arrangements for additional camera functions. The contact for the transfer of information is also employed as a power supply contact.
