Anamorphic lenses for BMPCC 6K with EF mount?

Hi guys,
I am pretty sure that this question most likely was asked before, I just want to make sure there is no "hidden" loops that I am not aware of.
If I am not mistaken it was written somewhere that because of the way EF mount is built the sensor is too close to the lens, and therefor there are no (inexpensive) anamorphic lenses for it.
But then I saw a Youtube video where guy is showcasing some Laowa lenses with EF mount, and I see a lot of old Russian anamorphic lenses modified for EF mount.
So, I guess this is the answer, there are as many anamorphic lenses for EF mount as for any other mount, and what I have heard about some EF mount limitations is not true, right?
Thank you.

The limitation is not being too close to the sensor, but just the contrary, the flange depth of EF is too long. And since the world is moving away from mirror cameras, there are hardly any new, low cost Chinese anamorphics made. But you can work with standard lenses (not too long) and front-mounted anamorphic converters, like the Century optics or lenses initially made for projection. You may have to go second hand.

Thank you for your reply.
These 2 links show anamorphics designed for EF and used on BMPCC 6K, so, these are real deal and will give the anamorphic effect with no problems, right?

Can't answer, I only ever used Century.

Is it an anamorphic lens, or an adapter that goes in front of a lens?

That's an adapter.
