On various cameras the triggering control only
works in the "P" mode and the shutter priority
mode "S" (see operating instructions for the came-

some camera models: To do so, press and hold
down the flash button

flash ready signal will again be displayed in the
camera's viewfinder when the shutter release is
lightly touched. The camera selects a suitable
shutter speed/aperture combination and a flash is
fired when a picture is shot.
On the Dynax 800si, the triggering control fea-

tal cameras Dimage A1, A2, 5, 7, 7i, 7Hi .

camera. This sensor measures the light that rea-

camera sends a signal to the flash unit which cau-
