Re: How did you stack the EF 2x III and EF 1.4x III

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?
