This comparison is incomplete as it only covers the hardware specs and doesn’t mention the changes in software. This is important as it greatly impacts the compatibility with other devices. I bought a gimbal, for instance, which is compatible with the A7RIV, thinking it would also be compatible with the A7RIVA. Turns out it isn’t.
It would be hard to list all the compatibilities with all third-party devices. Impossible, probably. But I do appreciate you adding your experience!
