I bought a Ronin RS3 mini yesterday only to discover that Bluetooth is not compatible with the Fuji XT-4. Should have checked before I bought it but how is it that such a popular, best selling camera is not compatible?

Hey, phillipennis!

Hope you are well, thank you for the time to reach out to us. I am so sorry to hear about this compatibility issue.

Upon checking, Thanks for the feedback, at present Fujifilm series does not support Bluetooth connection due to camera protocol limitations.
Currently, we have already feedback on the related function demand to the engineer for further evaluation.
If Bluetooth is supported in the future, it will be updated through the camera compatibility list on the official website, so please pay attention to the camera compatibility list on the official website.

Thank you very much for your time and efforts. Let me know if l can do anything more.
