In a photographic exposure control system of the type which provides a flash fire signal at an appropriate follow focus aperture value corresponding to the camera-to-subject distance range and which terminates the exposure interval as a function of scene light detection and integration to a select level, there is provided an arrangement by which the exposure control system may be selectively adjusted to accommodate any one of a variety of different film speeds.
