The Transcontinenta Group, distributor NiSi Benelux, introduces the all-new NiSi 9mm F2.8 ultra-wide angle for APS-C Sony FE, Canon RF, Nikon Z and Fuji-X mirrorless cameras as well as M4/3 cameras.

Oh, but Canon doesn't allow third part RF lenses.
Try again, but do make some attempt to do some research first.

The NiSi is a manual lens. Canon does not prevent anyone manufacturing or selling manual RF lenses.

Wex lists 23 Laowa RF lenses, 2 Samyang RF lenses and 3 Kipon RF lenses, including:

Samyang/Rokinon 14mm F2.8
Samyang/Rokinon 85mm F1.4

Kipon 24mm F2.4
Kipon 50mm F2.4
Kipon 90mm F2.4

Laowa 12mm Zero-D F2.8

Oh, and there are also 19 Lensbaby RF lenses.

... and of course, no less than 30 of Canon's own RF lenses, all with AF.

You're rather spoilt for choice aren't you?
