Recommend a Gimbal for Sony A7s on Octocopter

Learning about gimbals for my s1000 frame has proven to be spotty on information. Gimbals I have seen and looking at so far are; Movi M5, Gremsy T3, and DYS A7. For all three, there’s barely any information I’m finding. For the Gremsy, I can’t even get a response from anyone at Gremsy, and for the DYS, I can’t find anything other than it exists (existed?) let alone how to integrate it.

Can anyone recommend a gimbal that I am unaware of yet?
