Yes the resin layer has optical properties but it is basically a coating with differential thickness to mimic the qualities of an aspherical surface in order to save costs on grinding/polishing. There's a difference between a layer and an element (lens). His reference to the NDA was to imply that he had information directly from industry that was proprietary and that he could not disclose, which didn't make sense if he is speaking about lenses that have already seen production.</blockquote>
