Notes on Optional Flash Units
Refer to the Speedlight manual for detailed instructions. If the flash
unit supports CLS, refer to the section on CLS-compatible digital SLR
cameras. The D3400 is not included in the "digital SLR" category in the
SB-80DX, SB-28DX, and SB-50DX manuals.
If an optional flash unit is attached in shooting modes other than j, %
and 3 the flash will fire with every shot, even in modes in which the
built-in flash can not be used.
i-TTL flash control can be used at ISO sensitivities between 100 and
12800. At high ISO sensitivities, noise (lines) may appear in photos
taken with some optional flash units; if this occurs, choose a lower
value. If the flash-ready indicator flashes for about three seconds after
a photograph is taken, the flash has fired at full power and the
photograph may be underexposed (CLS-compatible flash units only;
for information on the exposure and flash charge indicators on other
units, see the manual provided with the flash).
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 choose spot metering to select standard
i-TTL flash control. 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.
If the controls on the optional SB-5000, SB-910, SB-900, SB-800, SB-700
or SB-600 flash unit or SU-800 wireless Speedlight commander are
used to set flash compensation, Y will appear in the information
display.
