I've just bought the Godox XPro wireless flash trigger to use it with my Pentax cameras and remotely trigger my TT685F flash. There is an unusual problem in TTL mode: the flash fires every time, but every other frame is dark as if the flash was out of sync. It happens with both my Pentax cameras – KP and K-S2.
I let the flash recharge before pressing the shutter button and use slow shutter speeds like 1/50 to 1/100 s. Turning high speed sync on and off didn't help. I tried to set different flash modes in camera, but the problem persists.
In manual mode, every frame is lit.
Any advice?
