DNotes on Optional Speedlights

Refer to the Speedlight manual for detailed instructions. If the Speedlight supports the Nikon Creative Lighting System, refer to the section on CLS- compatible digital SLR cameras. The D300 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 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.

The SB-900, SB-800, SB-600, and SB-400 provide red-eye reduction in red- eye reduction and red-eye reduction with slow sync modes, while the SB-900, SB-800, SB-600, and SU-800 provide AF-assist illumination when the conditions for AF-assist illumination are met. With other flash units, the camera AF-assist illuminator is used for AF-assist illumination. When used with AF lenses with focal lengths of 17–135 mm, the SB-900 provides AF- assist illumination (active AF-assist illumination) for all focus points; note, however, that autofocus is available only with the following focus points:

17–19 mm 20–105 mm 106–135mm

When used with AF lenses with focal lengths of 24–105 mm, the SB-800, SB-600, and SU-800 provide AF-assist illumination to assist autofocus for the following focus points:

24–34 mm 35–49 mm 50–105mm

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

n

Maximum aperture at ISO equivalent of:

200	400	800	1600	3200
5	5.6	7.1	8	10

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.
