Abstract

A camera is capable of using a film cartridge bearing code indicia indicating the film speed of the film contained in the cartridge. The camera comprises first means for detecting the film speed from the code indicia of the film cartridge loaded in the camera and generating a first corresponding signal, and second means for manually setting the film speed and generating a second corresponding signal. The camera further comprises discriminator means connected to the first and second means and adapted to generate an output signal upon detection that neither the first nor the second signal is generated, and means for generating an alarm in response to the output signal of the discriminator means.
