But one strange anomaly still exists (and this was pointed out by one person in this thread). By design, a RF tele won't fit on a EF2RF adapter. But yet the RF 600F4 and RF 400F2.8 lenses violate this design by allowing a RF tele to fit on the back of the (built in) EF2RF adapters on those 2 lenses. This tells us that Canon modified the EF2RF adapter that they welded onto the RF 600F4 and RF 400F2.8 lenses.

don’t understand what this means.

I think your original questions show correct understanding, but I am not sure your conclusion is correct. Look into extension rings

Quite simple, try to connect a RF teleconverter to the (camera side) of a EF2RF adapter - it wont fit because of the baffle that is on the end of the teleconverter is too large in diameter to fit into the EF2RF adapter.

Differently, the same RF teleconverter will connect/fit into the EF2RF adapter that is permanently connected to the RF 400 F2.8 and RF 600 F4 lenses.
