D Notes on Optional Flash Units
Refer to the flash unit manual for detailed instructions.
If the unit
supports CLS, refer to the section on CLS-compatible digital SLR
cameras. The D5 is not included in the “digital SLR” category in the
SB-80DX, SB-28DX, and SB-50DX manuals.
i-TTL flash control can be used at ISO sensitivities between 100 and
12800.
At values over 12800, the desired results may not be achieved at
some ranges or aperture settings.
If the flash-ready indicator (M) 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).
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 monitor.
In i-TTL, use the flash panel or bounce adapter provided with the flash
unit.
Do not use other panels such as diffusion panels, as this may
produce incorrect exposure.
In exposure mode P, the maximum aperture (minimum f-number) is
limited according to ISO sensitivity, as shown below:
Maximum aperture at ISO equivalent of:
100 200 400 800 1600 3200 6400 12800
4 4.8 5.6 6.7 8 9.5 11 13
If the maximum aperture of the lens is smaller than given above, the
maximum value for aperture will be the maximum aperture of the lens.
Noise in the form of lines may appear in flash photographs taken with
an SD-9 or SD-8A power pack attached directly to the camera. Reduce
ISO sensitivity or increase the distance between the camera and the
power pack.
