There's an easy way to tell if your Fuji camera does HSS.
Unlike all the other camera brands supported by the Godox X system, Fuji's HSS setting is controlled by the camera, not by the transmitters. If you have a camera menu selection to set
AUTO FP(HSS) on the flash, then you can do HSS. If you don't, you can't.
HSS was added as a feature to the Fuji X flash system in late 2016 with the arrival of the EF-X500 speedlight. So, generally, only the higher-end bodies made in 2016 or later can perform it (with the exception of the X-T1, which can have its firmware updated to v5.0 or later to include this menu command). However, post-2016 production is no guarantee, as the lower-end 2018 models, the X‑T100 and X‑A5, both lack HSS support.
So, the other easy way to check is to go to the Fuji website's flash X System compatibility chart and look at the EF-X500 column. If your camera model is footnoted with a 1, it cannot do HSS. If it's footnoted with a 2, it can, but with newer-than original firmware. And if it's footnoted with a 3, it can do HSS.
At the time of this posting, the Fuji bodies that can do HSS with Godox gear are:
- GFX 50S
- GFX 50R
- X-T1 (firmware updated to v5.0 or later)
Godox HSS with Fuji
If the Godox gear you're using has built-in 2.4 GHz radio triggers and performs TTL, and is for Fuji you can have HSS with an HSS-capable Fuji body.
If the light is not for Fuji, then it must also have up-to-date firmware that can understand the Fuji signalling (see: How do I tell if my Godox trigger or flash needs a firmware update?).
If it's a non-F version of the TT350/V350, it may or may not work in TTL/HSS fully or partially, depending on which "flavor" it is. And the X1R receivers don't do cross-brand TTL/HSS at all.
And, with the following gear, there are additional caveats:
- AD180, AD360 (Mark I) + XTR16 receiver
- Mark I V850 and V860 + XTR16s receiver
- TT600 / TT600S
- V850 II
These lights/triggers will not do HSS with the XPro-F transmitter, only with the X1T-F transmitter. And:
- The X1T-F must have its firmware at v3 or later.
- C.Fn-11 must be set to either 01 or 02 (reports vary on which one gets HSS to work with the XTR16/XTR16s). It must be set to 02 to work with the TT600/V850II.
- With the add-on receivers, HSS must be set directly on the flash itself.
