Abstract
A photographic information setting device for a camera according to the present invention includes a film speed reader which reads out a film speed value provided on a film container, a micro computer and three memories. A first memory is for storing a film speed value of a film in use, a second memory is for storing a film speed value of a film used immediately before the film in use, and a third memory is for storing a film speed value to be used in deciding an exposure value for a camera. The micro computer compares the film speed values in the first and second memories and, when the two values are the same, it controls in such a manner that the film speed value in the third memory may not be altered. On the other hand, when the two values are different, the micro computer controls in such a manner that the film speed value in the first memory may be stored in the second and third memories.
