Using Pop-Up flash to trigger Godox TT685

I just bought an X100v. So far, I am loving it. So here is the deal. Since I sold my sony setup, I can't use my godox sony compatible speed-lights.

I will buy the wireless trigger for fujifilm. I am just wondering if it's possible to trigger my sony tt685 on x100v's pop-up flash. I searched the web but I couldn't find anything related to Fuji.

Yes, but it's manual-only triggering (no TTL, HSS, etc. and all settings changes have to made directly on the speedlight). You can use the S1/S2 optical slave modes.

There are simple "dumb" sensor-based slave modes, which do a "see flash burst, fire flash" thing. S1 fires on the first burst sense, (pop-up in M mode). S2 fires on the second burst sensed (pop-up in TTL with a single metering preflash burst).

The X100V is new enough that it has Fuji's "smart" optical wireless capability built in, so whatever you do, DO NOT set MASTER FLASH on the X100V's popup. That's for using the EF-X500 speedlight as a "smart" optical slave, and will fire multiple preflashes to communicate settings changes.

If there's a red-eye reduction flash setting you want to turn that off as well, since that also uses preflashes.

When your Godox Fuji transmitter arrives, you need to check that your TT685-S has the correct firmware version to understand the Fuji TTL signalling, since the Sony version of the TT685 came out before Godox rolled out Fuji TTL support. The C.Fn menu shows the firmware version that's currently loaded. Fuji TTL support was added in v2.0. Current version is 2.1 (added ID codes and the ability to turn the blinking red LED on the front off when it radio slave mode).
