Abstract
A camera is adapted to operate with stored data by sensing the film speed data prepared on the surface of a film cartridge loaded in the camera to produce a data reading signal and reading the sensed film speed data in response to the data reading signal and detecting whether or not the the film loaded in the camera includes film speed data to provide a warning when a determination is made that the film speed data is not on the film cartridge. Film speed data may be loaded in the camera manually and the warning is interrupted in response to the manual setting of the film speed. At least one of the film speed data and the manually set film speed data is stored and the exposure data is calculated on the basis of the stored film speed data.
