ABSTRACT:
A pseudo format camera system comprises a film cartridge including a memory which stores film speed data and limitation data, and a camera including a means for setting pseudo focal length, a means for inputting the film speed data and the limitation data from the memory, a means for controlling exposure based on the film speed data, and a means for limiting the pseudo focal length depending on the limitation data. In this camera system, the pseudo focal length can be limited based on the limitation data stored in the memory in the film cartridge, and therefore it is surely prevented that a picture becomes rough because of a bad grainness of a film.
