To answer my own question, I looked at the diagrams of both the EF and RF 14/2.8 autofocus lenses. It is a new design.I wonder if its an EF lens with a revised mount for the RF bodies. Basically, a built-in adapter. The spacing between the rearmost lens element and the sensor will tell the story.
It looks to be an RF-mount adjusted version of the Samyang 14mm F/2.8 FE lens.Wow, interesting new design. I have the EF version and like it a lot. I'll look forward to comparisons and pricing.
