Follow these steps to set up an optical communications controlled wireless external flash. Check your product manual for model-specific information.

  1. Attach the external flash to the flash accessory shoe of the camera.
  2. Turn on the camera.
  3. Set the camera to one of the following modes:
    • Program Shift (P)
    • Aperture Priority (A)
    • Shutter Priority (S)
    • Manual (M)
  4. Turn on the external flash.
  5. Set the camera to the wireless flash mode.
    • The external flash is set to wireless mode automatically and WL displays in the flash data panel.
    • The camera's flash switches from being a light source to a controller.
    • The light output of the camera's flash is reduced to the point that it doesn't affect the exposure.
  6. Remove the external flash from the camera.
    • To add an external flash, manually match each additional flash to the configuration of the first flash.
    • Set each additional flash in remote (RMT) mode.
    • Additional flashes need to be set to use the same channel, like CH1, CH2, CH3, or CH4.
  7. Set up the control flash:
    • For an A-mount α (Alpha) camera with a built-in flash, raise the built-in flash.

    • For other compatible cameras, attach an external flash to the flash accessory shoe.

  8. Set the appropriate exposure settings on the camera.
  9. Take a picture.

Note:

  • The flash on the camera triggers the external flash when the picture is taken.
  • ADI metering is canceled and the P-TTL flash metering is used automatically in wireless flash mode.
  • If you need to mount the flash, use the 1/4" tripod mount of the supplied mini-stand. Don't use an ADP-MAA shoe adapter which may prevent the flash from firing wirelessly.
  • Additional information on using wireless flash with optical and radio communications is available.
