In this mode, the flash is emitted according to the guide number (GN) setting.
Displayed according to the
focal distance of the lens.
Guide number (GN)
Optimum shooting distance
1.
The control panel shows the current guide number (GN)
together with the optimum shooting distance according to
the camera setup.
2.
Turn dial A to set the GN. (This is also possible by turning
dial B.)
Set the GN so that the optimum shooting distance is equal
to the subject distance.
When the optimum shooting distance is 0.6 m (0.5 m in
case of close-up flash) or less, the displayed figure blinks
to warn that the subject is located outside the flash light
emission area.
The optimum shooting distance varies according to the
camera setup (ISO speed, lens iris (F), lens focal distance
(ZOOM), and shutter speed). See page 30 for details.
Memo:
Assuming that the ISO speed is 100, the optimum shoot-
ing distance can be calculated with the following formula.
Optimum shooting distance = Guide number (GN)/Lens iris (F)
(See page 30.)
