Aren't most aspherical elements in modern lenses simply molded anyway? Shouldn't be too hard to mold those hypergon elements... the fact that they are symmetrical makes it even simpler !

People could then buy all the hypergons they dream about and realize how much the wide-angle lens design process has improved over the last 150 years !

But then again, there are no modern lenses that go that wide...

Cheers,
