Flash Troubleshooting

  • As I zoom my lens, my flash’s zoom head does not work.

    Ensure the 17mm Wide Panel is not down and covering the flash head as this will stop the zoom mechanism from working.
  • My flashgun does not charge up.

    Check the batteries have sufficient power in them. Check the contacts are clean and the batteries have not leaked. If the problem persists, please return your flashgun for inspection.
  • The exposures from my flashgun seem to be erratic.

    Ensure you are using the correct fitting flashgun, ie. a Canon fit gun on a Canon camera. Ensure the flash / camera is not on Manual mode. Ensure the 17mm Wide Panel is not covering the flash head. If using a digital camera, ensure the model is compatible See our compatibility chart for details. We suggest using spot metering for more accurate results. If the problem persists, please contact us for further information.
