Replying to Looking for a new camera for Film

Budget is around 3k for lens+camera. Most looking for camera.

Currently I use a Sony fs100, which is solid but I'm looking for something smaller that still packs a punch. I was looking into the Sony a7sii or the GH5. Both are around the price point i'm looking at for a body.

Can someone let me know if they own these cameras what they like about them? Or if there is a better or equal camera out there that still captures solid footage?

I'll be using it for B-footy and skiing footy, as well as for some short films
