This cage has the same layout as the small setup cages, except that it has an integrated Arca-Swiss plate on the bottom of the cage. The cage fits my a7siii perfectly and feels like a small rig cage. The only downsides, in my opinion, are the lack of a strap loop on the top right side (power button side) and the fact that the cage isn't made out of one piece. Overall, the biggest benefit for me was the integrated Arca-Swiss plate, which eliminates the need to attach an additional plate.
