hi, has anyone found one of these that is compatible? I have searched hopeless Godox literature for compatibility chart. Z50 is no guide unfortunately.
The newer a model is, the less likely it's going to show up on a Godox compatibility chart, because that chart just lists everything Godox had in-house to test against when they were developing it. They rarely go back and update to include newer camera bodies as they get released, and they probably can't afford to buy one copy of every camera model that comes out and still keep their gear low cost.
Non-inclusion on that list doesn't mean a newer body is incompatible, just that Godox didn't test their gear specifically against that model. Unless Nikon drastically changed the hotshoe/flash electronic communication protocol with your specific model (not something the camera manufacturers tend to do very often), it's likely that all the N-designated Godox transmitters are compatible with it (X3-N, XPro II-N, etc.)
And any incompatibilities are why we like Godox building in the ability to update the firmware on their transmitters/flashes, so that fixes are possible.
Godox gear costs less than half the price of OEM flash gear. Expecting everything to be 100% compatible and just as good as OEM is... unrealistic. You want cheaper flash gear? Then this type of living-with-bugs things is part of the low-low price tags, as well as the possibility of having to exchange a lemon copy being higher. (And this is also why we like buying from Adorama or B&H, who we know stand behind Godox warranties).
Despite all this, Godox is still solid enough and useful enough to be the default recommendations nearly everywhere on the interwebz. The performance/price ratio is good enough for pros to use the gear.
All this just to say that a $60-$90 trigger maybe having some quirk or incompatibility bug isn't worth freaking out about. Even if it has one, the chances are good that the 10% of function you'll use 90% of the time (remote firing, remote power control by group) is highly likely to function just fine. Just me, get one of the newer models, the X3N or the XPro II-N, and see. If it's catastrophically non-compatible, then return it and/or wait for a firmware fix. Or pony up for Nikon OEM or Profoto triggers and speedlights.
