Using LCD Panel For Shooting-Distance Computation
Confirming flash shooting distance is an indispensable step
for successful flash photography. The SB-25 can be used to
compute the appropriate distance range.
An appropriate flash shooting distance is determined
using the following variables:
• ISO FILM SPEED IN USE
• APERTURE VALUE
• ZOOM-HEAD POSITION
Indicator bars will appear to show a proper shooting
distance range only after all those variables have been set in
the LCD panel.
Setting ISO Film Speed (Manual Adjustment)
1 Push button so a film speed number starts blink-
ing beside the indication in the LCD panel.
2 Press adjustment button or to set the film
speed.

Automatic ISO film speed adjustment: F90-
Series/N90, F4-Series, F-801/N8008, F-801s/
N8008s
No manual adjustment is required with these camera
models, because ISO speed of film in use is automati-
cally set and indicated in the SB-25’s LCD panel.
When a film is not installed in the camera, ISO 100 is
indicated.
If no indication shows in the LCD panel, lightly press
the camera’s shutter release button.
Operation in Repeating Flash Mode
Setting of ISO film speed is not required. The repeat-
ing flash indicator appears in the place of the film
speed indicator. For details, see pages 90 to 95.
