8 Set aperture in the SB-25's LCD panel*, then read the shooting distance
range.
For instruction, see "Setting Aperture Value (Manual Adjustment)," pages 28 to 29.
In aperture-priority auto or manual exposure mode, set the aperture value that you
have set on the camera (from step 6).
In programmed auto or shutter-priority auto exposure mode, aperture is automati-
cally controlled by the camera. Choose and set a value, using the "Guide to
determining aperture" in the following page.
Once aperture is set, indicator bars show the shooting distance range.
* This operation is important for reading the appropriate shooting distance from the indicator bars (step 9);
setting a wrong aperture value on the SB-25 does not affect all TTL Auto Flash operations — a shot will be
taken with the aperture set on the camera.
TTL Auto Flash Mode: For F-401x/N5005 Users
9 Confirm shooting distance.
Check whether subject falls within the
range of the shooting distance indica-
tor bars in the SB-25's LCD
panel. If not, move closer to subject or
select a wider aperture (when aper-
ture-priority auto or manual exposure
mode), then repeat steps 8 and 9.
