Yes but once again, it's how much you PAID. Since Rokinon and Tamron are lots cheaper than Canon L glass, they don't get to use the Red Ring Picture Frame. More to the point, how about lenses that are MORE expensive than Canon L glass? Yes, I'm looking at you Zeiss Otus!
But, But that Otus is a tiny little lens, and it doesn't even have autofocus, how could that be a special magical lens!
