    What to do if my Nikon autofocus speedlight SB-900 Camera Flash SB-900 does not fire?
    • A

      The Nikon Camera Flash SB-900 may not fire due to several reasons: * The custom setting “Canceling flash firing” might be activated, so you should cancel it. * The master and remote flash units might be too close to each other. Ensure they are placed at an appropriate distance. * The SB-900’s temperature may have risen. Allow it to cool down naturally.

    Why does the flash shooting distance range not appear on my Nikon autofocus speedlight SB-900 Camera Flash SB-900?

      The flash shooting distance range may not appear because: * The flash head is not set to the horizontal/front position. To resolve this, set the flash head to the horizontal/front position. * Aperture information has not been received from the camera. Confirm the camera setting and mount the SB-900 to a camera. * The SB-900 cannot receive the focal length information from the camera. Try turning off the SB-900 and camera, and then turn them on again.

    How to fix zoom position when it does not set automatically on Nikon autofocus speedlight SB-900 Camera Flash?
    • B
      Bryan AndersonAug 4, 2025
      If the zoom position on your Nikon Camera Flash does not set automatically, it could be due to: * The built-in wide-flash adapter being in use or the Nikon Diffusion Dome being attached. Remove these attachments or set the custom setting “Zoom position setting if the built-in wide-flash adapter is broken off accidentally” to manual. * The power zoom function being canceled. Activate the auto power zoom function.
