TTL Auto Flash H Mode: For F-401/N4004 and F-401s/N4004s Users
Guide to determining aperture
Use these suggestions as a guide for choosing aper-
ture.
In programmed auto (ISO 100)
For subjects backlit by the sun f/16
For outdoor subjects on a sunny day f/8
For subjects beside a bright window f/5.6
For indoor subject f/5.6
In shutter-priority auto
For subjects backlit by the sun f/16 at 1/100 sec.
For outdoor subjects on a sunny day f/8 at 1/100 sec.
For subjects beside a bright window f/5.6 at 1/100 sec.
For indoor subjects f/5.6 at 1/30 sec.
8
Confirm shooting distance.
Check whether subject falls within the range of the shooting
distance indicator bars / in the SB-26’s LCD panel. If
not, move closer to subject or select a wider aperture (when
aperture-priority auto or manual exposure mode), then
repeat steps 7 and 8.
Confirming Settings
7
Set aperture in the SB-26’s LCD panel*.
For instruction, see “Setting Aperture Value (Manual
Adjustment),” pages 28 to 29.
In programmed auto and shutter-priority auto exposure
mode, set an aperture using the “Guide to determine aper-
ture” in the following page.
In aperture-priority auto or manual exposure mode, set the
aperture value that you have set on the camera (from step 6).
Once aperture is set, indicator bars / show the shooting
distance range for that setting.
* This operation is important for reading the appropriate shooting distance from
the indicator bars (step 8); setting a wrong aperture value on the SB-26 does
not affect all TTL Auto Flash operations — a shot will be taken with the aper-
ture set on the camera.
Setting Up Your Camera
5
Select one of the following exposure modes:
a. Programmed auto (A/S) to perform Programmed
TTL Auto Flash.
b. Shutter-priority auto (S) to perform Programmed
TTL Auto Flash.
c. Aperture-priority auto (A) to perform Standard TTL
Flash.
d. Manual exposure mode to perform Standard TTL
Flash.
6
Perform other settings:
a. For shutter-priority auto, set desired shutter speed*.
b. For aperture-priority auto, set desired aperture.
c. For manual exposure mode, set desired shutter
speed* and aperture.
* Camera automatically shifts to the fastest synchronization speed if you choose
a speed that is not within the synchronization range.

usable apertures and flash shooting distance
