Camera (built-
in Speedlight)

60–30 °

30 ° or less

10 m /33´ or
less

The maximum distance between the optional Speedlights and the camera is
about 10 m (33´) when the Speedlight is positioned in front of the camera
(within 30 ° on either side of the center line), or about 5 m (16´) when the
Speedlight is to the side (30–60 ° to either side of the center line).

Commander Mode

Press the button to raise the built-in Speedlight. Position the sensor windows on the
optional Speedlights where they will pick up the monitor prefl ashes from the built-in
Speedlight (take particular care when not using a tripod). Be sure that direct light or
strong refl ections from the optional Speedlights do not enter the camera lens (in TTL
mode) or the photocell on the optional Speedlight (AA mode), as this may interfere with
exposure. To prevent the timing fl ashes emitted by the built-in Speedlight from appear-
ing in photographs taken at short ranges, use a low sensitivity and small aperture (large
f/-number) and choose a fl ash sync mode other than rear-curtain sync. After position-
ing the Speedlights, take a test shot and view the results in the camera monitor.

Although there is no limit on the number of optional Speedlights that may used, the practi-
cal maximum is three. With more than this number, the light emitted by the other fl ash units
will interfere with performance. All Speedlights must be in the same group; fl ash compensa-
tion (

102) applies to all Speedlights. See the Speedlight manual for more information.

Commander mode settings of AA (SB-800 only) and TTL are available with CPU
lenses only. If a non-CPU lens is attached, the shutter release will be disabled. The
fl ash-ready indicator ( ) in the viewfi nder and the icon and borders of the fl ash sync
mode indicator in the control panel will blink.
