Is the issue with compatibility between ronin s and nikon d750 fixed? Reading forums and i cant find anything. The only thing i can find is that you are working on the solution (since 2018). if ronin-s is not compatible could you advice which gimbal is with nikon d750?

They are not working on it.
At least, that is my assumption.
There probably are not enough filmmakers using the D750 to invest time (and money) in that part.
Especially now that Nikon added the Z series (that is aimed for videographers much more).
But it is a shame, since I would buy the moment they add D750 support....
And so might you.
So  let's spread the word!

I have it at home. But I guess I have to send it back. And look if the the other gimbal companies support it.
