That is exactly what I mean, the exposure is constant with any
shutter/aperture combination under a fixed ambient light. Most people think
you can extend the working distance by using higher speed film or use a
slower shutter speed. But in Super FP mode, both are not the parameter to
get longer flash working distance. It is under ambient light controlled, the
brighter the ambient the short flash working distance or the less flash
effect.

It makes my head hurt just to think about it. The F280 manual has a
chart that shows increased range for the flash with higher film
speed, larger F stops and slower shutter speed. Of course with with
higher film speed the automatic exposure system will operate to
decrease the light coming into the camera from both ambient and flash
sources. I guess you carry the chart.
