3 When the desired number
appears, press
button to
complete setting. The indication will
stop blinking.
The film-speed indicator blinks during
adjustment, and stops blinking after
eight seconds unless an adjustment is
made with an adjustment button. The
last blinking number is automatically
set in this case.
Setting Aperture Value (Manual Adjustment)
1 Push button so an aperture
value number starts blinking
beside the indication in the LCD
panel.
2 Press adjustment button or
to set the aperture value.
When camera is in programmed auto
or shutter-priority exposure mode, be
sure to use an aperture indicated in
the camera’s viewfinder (a “controlled
aperture”).
In general, first set the aperture on the
camera, then use the same value for
the SB-25.
3 When the desired number
appears, press
button to
complete the setting. The indication
will stop blinking.
The aperture-value indicator blinks
during adjustment, and stops blinking
after eight seconds unless an adjust-
ment is made with an adjustment but-
ton. The last blinking figure is auto-
matically set in this case.
Automatic aperture
adjustment: F90-Series/
N90, F4-Series, F-801/N8008 or
F-801s/N8008s used with an AF
Nikkor lens (including the lat-
est D-Type) or Nikkor lens hav-
ing a built-in CPU
No manual adjustment is
required with these camera/lens
combinations, because the con-
trolled aperture is automatically
set and indicated in the SB-25’s
LCD panel (except in Non-TTL
Auto Flash
mode).
Setting Zoom-Head Position (Manual Adjustment)
Press the button until the number
in the LCD panel shows the focal
length of the lens in use or shorter.
When using a zoom lens other than AF
Zoom Nikkor, set the shortest focal
length of the lens to determine the
zoom-head position that covers the
full zoom length range.
Also, refer to page 139 on “Angle of
coverage,” an angle which flash light
can cover in a zoom-head position.
