If so what are your thoughts? I have a custom built mini-rig for my A7s and it uses some SmallRig parts and I find them very well machined - the cage looks really good as it's smaller than most, has a nice anti-twist plate and comes without a top handle, which I don't need. Tbh I'm not sure why they all seem to have a mandatory top handle - how are you meant to use the evf with that poking into you forehead?

You know you can point the handle FORWARD, or sideways, or sticking up if you want? :-)
I use a SmallRigs cage on my A7sII. It was the ONLY cage I could find that had a top hotshoe connection (solid bolt down), which keeps the camera body base from flexing like Jello from the weight of my 28-135!

The SmallRigs is a half cage, wrapping the left side of the camera, but with the II's, you get that meaty handgrip, so it would be a shame to put a bar across it. My cage is only used to mount a forward facign handle, and add a left side shoe for my shotgun microphone.
