Speedbooster for the EOS-R mount?

I've benefited from a custom-made EF-M to EF speedbooster on my Canon M50. It helps negate some of the crop on 4k.

I wonder if someone (Metabones, Viltrox, the engineer in South Korea) would like to make an EF-R to EF 0.71x (or 0.64x) reducer for the EOS-R?

Admittedly that does nothing for the EF-R lenses, nor does it make the camera great value overall, but it would allow for some flexibility on the video side of things with the wide range of EF lenses available.

You mean a speedboster for the EOS R in crop mode? It could be feasible.

Yes, that'd be it.

I suspect, however, that if a full frame Canon without a crop were to emerge in six months, then no one who could actually make the speedbooster would bother, but I hope someone still does!
