It looks like the Godox/Flashpoint system is working very well with Fujifilm cameras, you can even use Fujifilm Godox products to control other Godox/Flashpoint ecosystem products for other manufacturers. When the Godox XT1-F ships Fujifilm will have its first native studio/portable studio complete system available. I am tempted to add the Godox system to my Impact system with the RoboSHOOT, but I might be pushing things more than a little. These lights should work great with the X-T2 and GFX alike.
