A FujiRumors reader (thanks) had a chat with Elinchrom. He asked them when they will finally support Fujiflm, and their answer was that “it is coming this summer” and that more details will be announced “by the end of the month [June]”.
Now that was fast, Elinchrom, considering that you promised “Fujifilm support as next” back in March 2017 :).
Godox, Profoto, Nissin, Broncolor, Metz, Cactus, Priolite, Jinbei/Orlit, Conomark and more companies have already added Fujifilm support.
