Hoya's Multo Coating is usually vey good, the lens problem was a mistake in the design/production probably to cut costs it wasn't faulty coating rather they just didn't coat every air/glass interface. There's no problems with Hoya's top Tokinna range of lenses. Hoya used to hide the links between the two companies for some obscure reasons now the link is acknowledged openly.
