"Asahi was one of the very few 'real' lens manufacturers which means that they compose, melt, and work the different types of glass used in their lenses" Gerjan van Oosten, The Ultimate Asahi Pentax Screw Mount Guide, 1999. He could be wrong, of course. It is more likely that he is simply out of date and Pentax at some point outsourced glass manufacture. DJE
