cameras in Groups I to II, the ISO sensitivity is automatically set and appears
on the LCD panel when the camera and SB-800 are turned ON.

Available ISO sensitivity in TTL auto flash operation
The SB-800’s maximum ISO sensitivity range usable in the TTL auto flash mode
is ISO 25 to 1000.
• The ISO sensitivity range may become narrower, depending on the cameras in use. For
details, see your camera instruction manual.
• The flash shooting distance range on the SB-800’s LCD panel varies, depending on the
ISO sensitivity. Therefore, be sure to set the ISO sensitivity correctly.
u
Digital data communication with the SB-800
When the SB-800 is used with cameras compatible with CLS, digital SLRs not
compatible with CLS and cameras in Groups I to II, digital data communication
is performed. The camera automatically sends the ISO sensitivity to the
SB-800. With a CPU lens, the aperture and focal length are automatically
set on the SB-800.

Notes on setting the Speedlight’s ISO sensitivity
In the TTL auto flash mode and Manual flash mode (except Distance-priority
manual
p
flash), 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 (Auto Aperture flash
B
/Non-TTL auto flash
A
) and Distance-priority manual
p
flash operation, the correct exposure can
be obtained by setting the camera’s ISO sensitivity on the Speedlight, because
the Speedlight controls the flash output. For cameras compatible with CLS,
digital SLRs not compatible with CLS, and cameras in Groups I and II, the ISO
sensitivity is automatically transferred from the camera to the Speedlight.
