Try aperture-priority auto on the body, TTL on the flash, and lock
the aperture ring at minimum stop (assuming there is enough light
at the distances and film speed used... - if not, try using f11-16,
or try switching to manual, preselect 1/250th or higher shutter speed
[the camera will drop it to 1/250th when the flash is switched on],
and choose f11-16 [or, use a faster film with the first suggestion...]).
Hope This Helps
