A collapsible camera having an adjustable exposure regulating device incorporated in its movable shutter assembly is loaded with a film container having coding means representing a characteristic of film therein. When the camera is collapsed, a code sensing element of the shutter assembly is located adjacent to the film container and is influenced by the coding means to adjust the exposure regulating device. Means are provided to require collapsing of the camera whenever the film container is replaced to ensure that the exposure regulating device is adjusted by the coding means of the new film container.
