DNotes 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 D5000 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, the flash will fire with every shot even in modes in which the built-in flash can not be used (l, m, r, t, u, v, x, y, z, 1, 2and 3).
i-TTL flash control can be used at ISO sensitivities between 200 and 3200. At values over 3200, the desired results may not be achieved at some ranges or aperture settings. If the flash-ready indicator blinks for about three seconds after a photograph is taken, the flash has fired at full power and the photograph may be underexposed.
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-900, SB-800, SB-600, or SU-800 flash unit are used to set flash compensation, Y will appear in the information display.
