Interesting. Please post some samples, I have officially hijacked this thread (sorry mdvaden
)...If one expects only Canon made images, please close your eyes now!
Here are comparison image made with Konica 57mm f/1.2 (not a real 1:1 comparison)
and now the fullframe relative 48mm f/0.38 (but there I needed some croping due to light leaks):

The Canon 50/1 is the only AF lens ever produced @ <= f/1.
About mirrorless, there’s nothing under f/0.95 that covers full frame, not even the legendary NASA Zeiss lenses that R.Scott adapted for the movie Barry Lyndon...
With the Techart adapter one could likely use a converted Canon 50mm/0.95, so a bit faster than the Canon EF 50mm/1. And one can use Leica Noctilux 50/0.95 and f/1. So there are at least three Canon EF alternatives that may work with AF and are as fast as f/1 or faster - on mirorless Sony cameras.
If I remember right, some of the longer focal x-ray lenses covers medium format. But the mirrorless camera need some modification, to come close to the back lens, which is normal front pressure plate for the film. So the shutter has to go, depending on what you want to photograph. Machine Vision cameras could help.
But all the digital cameras are f-stop limited by the micorlenses or the sensor structure itself. So absolute f-stops faster than f/1 are not so good.
The Oude Delft 50mm/0.75 seems to cover fullframe:
