Optical AWL

Remote flash units can be controlled via optical signals from an optional flash unit mounted on the camera accessory shoe and functioning as a master flash (optical AWL). For information on compatible flash units, see “Features Available with CLS-Compatible Flash Units” (0Compatible Flash Units).

If the flash unit in question is an SB-5000 or SB-500, settings can be adjusted from the camera. For more information, see “Using Optical AWL with the SB-5000 or SB-500” (0Using Optical AWL with the SB-5000 or SB-500). See the documentation provided with the flash units for more information.
Settings for other flash units must be adjusted using flash unit controls. For more information, see the documentation provided with the flash unit in question.

Using Optical AWL with the SB-5000 or SB-500

Mount the flash unit on the camera accessory shoe. Select [Optical AWL] for [Flash control] > [Wireless flash options] in the photo shooting menu and choose a remote flash control mode (the SB-500 supports only [Group flash]). Choose a remote flash control mode and take pictures as described below.

The SB-5000

When an SB-5000 is mounted on the camera accessory shoe, [Flash control] settings can also be changed using the controls on the flash unit.

Optical AWL

Position the sensor windows on the remote flash units to pick up the light from the master flash. Particular care is required if the master flash is mounted on a hand-held camera.
Be sure that direct light or strong reflections from the remote flash units do not enter the camera lens (in [TTL] mode) or the photocells on the remote flash units ([qA] mode). Otherwise light from the flash units may interfere with exposure.
Even if [--] is selected for [Master flash] > [Mode], the master flash may emit low-intensity timing flashes. These flashes may appear in photographs taken at short range. This can be prevented by choosing low ISO sensitivities or small apertures (high f-numbers).
After positioning the remote flash units, take a test shot and view the results in the camera display.

Flash Info

Remote repeating options can be viewed using the [Flash info] item in the i menu, which can be added to the menu using Custom Setting f1 [Customize i menu].
