Notes on Optional Speedlights

Refer to the Speedlight manual for detailed instructions. If the Speedlight supports the Creative Lighting System, refer to the section on CLS-compatible digital SLR cameras. The D200 is not included in the “digital SLR” category in the SB-80DX, SB-28DX, and SB-50DX manuals.

If Auto FP High-Speed Sync is not used, the shutter will synchronize with an external flash at speeds of / s or slower.

i-TTL flash control can be used at ISO sensitivities between 100 and 1600. At values over 1600, 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 SB-800 or SB-600 is attached, AF-assist illumination and red-eye reduction are performed by the optional Speedlight. The camera provides AF-assist illumination when other Speedlights are used ( 58–59).

Auto power zoom is available only with SB-800 and SB-600 Speedlights.

In programmed auto, the maximum aperture (minimum f/-number) is limited according to sensitivity (ISO equivalency), as shown below:

Maximum aperture at ISO equivalent of:

100	125	160	200	250	320	400	500	640	800	1000	1250	1600
4	4.2	4.5	4.8	5	5.3	5.6	6	6.3	6.7	7.1	7.6	8

For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped down by half an f/-stop. 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.

When an SC-series 17, 28, or 29 sync cable is used for off-camera flash photography, cor- rect 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 your Speedlight. Do not use other panels such as diffusion panels, as this may produce incorrect exposure.
