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 D3300 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, %, 
3, ), and I, 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. At values over 12800, the desired results may not be achieved at 
some ranges or aperture settings. 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 
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-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.
