At least Samyang is also supporting it ;-)

I think it's not insignificant. The only real 85mm prime option for the system since the f/1.2 is priced like... well, like a new Canon f/1.2 lens would, and the rumored f/1.8 hasn't materialized yet, and somehow I doubt it's going to be really affordable either.

If this lens is the same optically as the FE Samyang 85/1.4, it's going to be a good one. The FE was reported to be excellent, much better than the DSLR version you tested last year in 2018.

An interesting offering, however Canon is not Sony and it shoulve severe competition from the EF lenses, EF 85mm f1.8 is now quite cheap even the 85mmf1.2 and F1.4 would compete very well on the price and quality side without forgetting all the EF third party lenses, so if it's not really good or aggressively priced it won't be an easy task selling.
Maybe a decent 50f1.4 would make more sense since Canon 50f1.4 is practically unusable wide open...

The 85/1.8 is adaptable to E-mount, too, so what? The difference is that there's a wealth of intermediate native options for the the E mount whereas in the RF mount you either go all out (85/1.2L), adapt, or... get this Samyang. I know I probably would go the latter route, because the L is very hard to justify in comparison - over 3x the price ($2700 at B&H) for just 1/3~1/2 stop larger aperture. Yes it's probably amazing but lots of people will never afford - or justify - the L.

I stick to EF mount and I'd just get the Tamron if I feel the itch for a fast 85.

f1.2 is used for lenses that are 1/2 a stop faster than f1.4. You do not get 1/2 a stop more light (most gets lost at sensor level), so only for more shallow DOF.

For EF I'd get the EF 85mm f1.8 USM if it should be able to capture action, and either the Tamron f1.8 or Canon f1.4 otherwise (both offer AF and IS, both render pretty nicely).
