Hello all,
I'm having what I believe is the same problem as you guys: I'm using a Fuji X-S10 together with the Godox X2T-F trigger (firmware version 1.3) , but they don't seem to communicate correctly.
The strange thing is that this happens only (as far I've tested) with the Fringer adapter EF-FX Pro II, AND Canon 50mm f/1.4.
I don't see this occurring with the same lens adapter and Canon 85mm f/1.8 or with an original Fuji lens, such as the 18-55mm.
The problem that I see is that the TTL mode is continuously switching between being on and off. Of course I can't shoot in this situation.
I tested the same trigger with Fuji X100F, and seems that everything is working correctly.
I assume the problem is with the specific configuration: X-S10, X2T-F trigger, EF-FX Pro II adapter, Canon 50/1.4.
