Optional Flash Units (Speedlights)
B Notes on Optional Speedlights
Refer to the documentation provided with Speedlight for details. If the Speedlight supports the
Creative Lighting System, refer to the section on CLS-compatible digital SLR cameras. The 060 is not
included in the "digital SLR" category in the S8-80DX, S8-28DX, and S8-50DX manuals.
The shutter will synchronize
with an external flash at speeds of 1/
2
00S
or slower.
i-TIL flash control can be used at
ISO sensitivities between 100 and 1600. Higher values may not
produce the desired results at some ranges or apertures. If the flash-ready indicator blinks in the
viewfinder for
about three seconds after a photograph is taken in i-TIL or Non-TIL auto mode, the
flash has fired at full power and the photograph may be underexposed.
The S8-400, S8-800, and S8-600 provide red-eye reduction, while
the S8-800, S8-600, and SU-800
provide AF-assist illumination (the SU-800 does
not prOVide AF-assist illumination in close-up mode).
Auto power zoom is available only with 58-800 and 5B-600 5peedlights.
In the following modes, the maximum aperture (minimum f-number) varies with 150 sensitivity
(t:l53).

For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped down by half an
fI-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
TIL Remote Cord SC-17, 28, or 29 is used for off-camera flash photography in i-TIL mode,
correct exposure may
not be achieved with i-TIL Balanced Fill-Flash control. We recommend that
you select standard i-TIL flash control. Take a test shot and view the results in the monitor.
In i-TIL mode, use the flash panel or bounce adapter provided with the 5peedlight. Do not use other
panels such
as diffusion panels, as this may produce incorrect exposure.
