Both Godox and Cactus are coming with Fujifilm compatible flashes. But let’s agree that up to now, flash has not been a strong suit of Fujifilm X cameras. That’s why I still use my Canon set because I need to do events and it’s almost impossible to make photos quickly without a reliable TTL functionality.

Many people have problem with the flashes not working. The same happens in both TTL modes and manual modes.

The flash does not work when:

  • The X-T1, X-T2, X-PRO2, X-T10, X-T20 are in silent mode. It disable the flash.
  • The X-T1, X-T2, X-PRO2, X-T10, X-T20 are set to use the Electronic Shutter (ES).
  • The X-T1, X-T2, X-PRO2, X-T10, X-T20 are in any bracketing/multiple exposure modes.
  • the flash is improperly seated in the hot shoe.

When both the flash and the camera are on, you should see either a flash symbol with “TTL” or “M” (depending on flash mode) on the viewfinder or the LCD.

If you do not see the flash symbol, then the flash is disabled.

The Fujifilm X-Trans cameras have a slightly different size than everybody else.

My Canon, Yongnuo and Godox flashes which fit perfectly in my Canon cameras are “loose” in the Fujifilm hot-shoes of the X-M1, X-T10, X-PRO2 and X-T2.

All flashes have a locking pin set but either a wheel at the bottom of the flash or a locking lever.

Make sure that the locking pin is engaged in the opposing hole of the hot shoe. Even then flash could still wiggle in the hot shoe.
