autoflash mode, the flash will be fired at full output only.

Set the camera’s shooting mode to <a> (manual exposure) or
<f> (aperture-priority AE) and adjust the aperture setting before
shooting.
 When using a Speedlite that has manual flash mode, shoot in the
manual flash mode.

Be sure to test the flash unit beforehand to make sure it synchronizes
properly with the camera.
