･ The SB-5000, SB-910, SB-900, SB-800, SB-700, SB-600, SB-500, and
SB-400 provide red-eye reduction in red-eye reduction and slow-sync
with red-eye reduction flash modes.
･ “Noise” in the form of lines may appear in flash photographs taken
with an SD-9 or SD-8A high-performance battery pack attached
directly to the camera. Reduce ISO sensitivity or increase the distance
between the camera and the battery pack.
･ The camera provides AF-assist illumination as required. AF-assist
illuminators on optional flash units will not light.
･ When an SC-series 17, 28, or 29 sync cable is used for off-camera flash
photography, correct exposure may not be achieved in i-TTL mode.
We recommend that you select standard i-TTL fill-flash. Take a test
shot and view the results in the camera display.
･ In i-TTL, do not use any form of flash panel (diffusion panel) other
than the flash unit’s built-in flash panel or supplied bounce adapter.
Using other panels may produce incorrect exposure.
