So, trying to get the IR[Ish] AF beam to work with the X1T-F on my X-PRO2. Some success in helping the camera's AF work, shooting into a very darkly lit black wall, the camera could not lock on but once I attached the X1T-F it would fire it's AF grid and BINGO, AF lock. Not happening all the time so I think it has to be dark enough for it to work.
Anybody here got more input on this?
