That explains it! Thank-you. So a less risky, non-do-it-yourself would be an EF 2x II, any EF 1.4x, and Canon EF to RF adapter? I am just trying to keep future possibilities open.

I am not sure if you mentioned it somewhere, but did you get autofocus with this setup? Would the setup I mentioned maintain AF?

I would recommend the RF 1.4x over the EF 2x ii. It will AF to infinity with an EF/RF adapter between EF 2x iii & RF 1.4x.
