lAvailable ISO sensitivity in TTL/D-TTL auto flash operation

is ISO 25 to 1000.
nThe ISO sensitivity range may become narrower, depending on the cameras in use. For
details, see your camera instruction manual.
nThe flash shooting distance range on the SB-80DX’s LCD panel varies, depending on the
ISO sensitivity. Therefore, be sure to set the ISO sensitivity correctly.
Notes on setting the Speedlight’s ISO sensitivity
In the TTL/D-TTL auto flash mode and Manual flash mode, there is no
direct connection between setting the ISO sensitivity on the Speedlight
and controlling the flash output level. Setting the ISO sensitivity is for
correctly displaying the flash shooting distance range or the shooting
distance indication on the Speedlight’s LCD panel.
In the Non-TTL auto flash mode and Auto Aperture flash mode, the correct
exposure can be obtained by setting the camera’s ISO sensitivity on the
Speedlight, because the Speedlight controls the flash output. In the Auto
Aperture flash mode, the ISO sensitivity is automatically transferred from
the camera to the Speedlight.
