In program mode, both aperture and shutter speeds are selected by the
camera. As the light level increases, ever smaller apertures and faster shutter speeds are selected. The shutter speed is shown in the VF (two
lights indicates an inbetween speed). To find out what aperture is being
used, move the aperture ring from the minimum f-stop (normally selected
for program mode) until the fault lights alternately blink in the VF,
indicating that you have selected an aperture slightly wider than the
one the camera would select, but which it cannot now use. "P" has the
disadvantage of usually using a wider aperture/faster shutter speed combination than I would normally select for lenses shorter than about
105mm. "A" and "M" modes avoid this problem. BTW, AI'd, AI, AIS, E,
and AF lenses will all work in program mode on the FG. Others have
explained how this is done.
Hope This Helps
