Notes on Optional Flash Units
Be sure also to consult documentation for the optional flash unit befor
e use.
If the unit supports CLS, refer to the section on CLS-compatible digital SLR cameras. This camera
is not included in the “digital SLR” category in the documentation for the SB‑80DX, SB‑28DX, and
SB‑50DX.
If the flash-ready indicator (c) flashes for about three seconds after a photograph is taken in i‑TTL
or non-TTL auto mode, the flash has fired at full power and the photograph may be underexposed
(CLS-compatible flash units only).
i‑TTL flash control can be used at ISO sensitivities between 64 and 12800 equivalent.
At ISO sensitivities over 12800, the desired results may not be achieved at some ranges or aperture
settings.
In mode P, the maximum aperture (minimum f-number) is limited according to ISO sensitivity, as
shown below:
Maximum aperture (minimum f-number) at ISO equivalent of:
100 200 400 800 1600 3200 6400 12800
4 5 5.6 7.1 8 10 11 13
If the maximum aperture of the lens is smaller than given above, the maximum value for aperture
will be the maximum aperture o
f the lens.
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.
