Adapter confusion

No one else is making adapters for A-mount lenses. Sony wants you to buy more. The LA-EA3 history is a good case. They did a firmware update for the A7II to allow it to focus motorized A-mount lenses with its on-sensor phase-detect using the LA-EA3, but they didn't add that to any other camera including the still popular A6000. The A6000 is otherwise more capable for AF than the A7II.

The A6100 and A6400 have a newer AF system than the A7III. The A7II and A7RII are not very good for AF-C. The A7RIII is not a good option either. It uses the old sensor of the A7RII with its more limited on-sensor phase-detect. Even the A7RIV is not a very good option for AF-C.

My inexpensive solution for burst AF-C is EF lenses with the Metabones IV adapter with the limitation being only the central AF points work. I am using the EF 70-200 F4L and 200 F2.8L and considering a Canon dSLR.

I wish I'd be happy with that fps and slow AF! Unfortunately, dogs are my big love for photography and so above all else, speed is important. It definitely limits what cameras I can get.

And to add, my plan if I go to the mirrorless would be to eventually either get the Tamron 70-180 2.8 or, if I could afford it (or get a used copy), get the Sony 70-200 2.8. I very rarely use much else.

The only two lenses I use regularly are my 135mm f/2.8 (for hiking with the dogs because it weighs nothing) and my 80-200 f/2.8.

I have a huge variety of lenses that get on the camera only once in a great while. So if I could just get ONE longer f/2.8 zoom for it I'd be good to go for the most part.
