~ Notes on Optional Speedlights
Refer to the 5peedlight manual for detailed instructions. Ifthe 5peedlight
supports the Nikon Creative Lighting 5ystem, refer
to the section on CL5-
compatible digital 5LR cameras. The D700 is not included in the "digital
5LR" category in the 58-80DX, 58-28DX, and 58-50DX manuals.
i-TTL flash control can be used at 150 sensitivities between 200 and 6400.
At values over 6400,
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 58-900, 58-800, 58-600, and 58-400 provide red-eye reduction, while
the 58-900, 58-800,58-600, and 5U-800 provide AF-assist illumination.
With other 5peedlights, the camera AF-assist illuminator
is used for AF-
assist illumination and red-eye reduction. When used with AF lenses with
focal lengths of 17-135 mm, the 58-900 provides active AF-assist
illumination for all focus points; note, however,
that autofocus is available
only
with the following focus points:
17-19mm

When used with AF lenses with focal lengths of 24-1 05 mm, the 58-800,

In programmed auto, the maximum aperture (minimum f-number) is
limited according to sensitivity (150 equivalency), as shown below:
Maximum aperture at ISO equivalent of:

For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is
stopped down by half an f-stop. Ifthe maximum aperture of the lens is
smaller than given above, the maximum value for aperture will be the
maximum aperture of the lens.
