Panasonic GH5 with Godox tt350o flash

Does anyone know if the GH5 is fully compatible with the Godox tt350o .

I don't, but I use one on a GX7, which also isn't on the compatibility list. In some ways it works terrific. In others... um... well...

Have looked at the Godox web site and it does not list the GH5 although they do list the

G85/G80 and the GH4 as compatible .

The list is basically the gear they had in-house to test with, not necessarily a complete compatibility list.

I don't want to invest in two flash guns and a trigger if they don't work out out the box so to speak .

It kind of depends on your definition of works.  Panasonic users seem to be having a slightly harder time, particularly with HSS function, than Olympus users with the Godox -O gear.  It's the perfect size/weight for my GX7.

My TT350-O works perfectly on-camera with my GX7. TTL, HSS, 2nd curtain, S1/S2, etc. all work as expected. My only big complaint is that it only swivels 270º.

As an on-camera transmitter with TT600 units as slaves, everything works perfectly. Remote power control and HSS are flawless. However, as a YN-622 user, I note that there's no remote zoom control, and no setting groups into MULTI mode remotely.

As an on-camera transmitter with a TT685C (I also shoot Canon) with upgraded firmware and in OLPS (Olympus) slave mode, however, the picture is muddier. If I use the combination indoors or in low light outdoors, everything works. If I then move this working combination to bright light (near a window, outside in sunny-16), everything goes to hell in a handbasket. TTL fires out of sync, and HSS refuses to fire at all. In M and out of HSS, remote power control and firing work fine. [facepalm]. Same behavior with my G3.

As a slave unit, it cannot do cross-brand TTL. So, using my TT685C as master on a 5DMkII and the TT350-O as slave meant that if I set TTL, it would only fire at full power. M mode power control and HSS worked fine. My iPhone+A1 can also control its power remotely, but obviously, without HSS or TTL function.

My recommendation is if you want it as an on-camera flash, don't hesitate. If you want it as an on-camera transmitter, consider getting an X1T-O or wait for the XPro-O. If you want it only as an off-camera slave, I'd recommend a TT600 instead, because it's cheaper and has more power and because Idon't have HSS issues with it. But. YMMV.
