HD is better than SMC, so it wouldn't make sense.
What, sorry? English isn't my primary language so I may have phrased it wrong. I meant Hoya didn't want to sell SMC (HMC) to Ricoh and Ricoh needed to come up with a new name or even with a whole new coating.

SMC (Super Multi Coating) is Pentax' own multicoating developed waaaay before Hoya took over (first introduced in 1971, actually). It was regarded as one of the best coatings, until the nano-coatings took the crown; and it's definitely not HMC.

HD is superior to SMC; and while Hoya has a similarly named coating, I am reasonably certain this was also developed by Pentax. There are many patents on this subject, showing that Pentax was actively developing new coatings.

That isn't likely. The patents on the SMC coating application process expired years ago (licensing the application process provided Asahi Optical Co. revenue from every lens maker except Leica for decades) and they had initially prucahsed the SMC coating formula from an American company.

It is far more likely Ricoh / Pentax invented and patented a new application process to multi-coat lenses, branded it HD and hopes to exploit its superior properties and/or lower cost of manufacture by licensing it to others.

Semi-related question: is it possible that Ricoh is substituting HD for SMC because Hoya wouldn't sell or license it? I just bought a new pair of glasses, and the lenses are HMCoated.
No, Ricoh has 35 current SMC Pentax lenses in their catalog.

Does it really have QS?? That would be awesome! But Pentax brochures often incorrectly claim that a lens has QS. Some Pentax brochures claim the 40mm XS has QS, for example. (and it doesnt have QS, I know because I have it)
The DA WR and non-WR 55-300's do, the DA L doesn't.
