Pentax uses Hoya glass as does Leica for some lenses. At the time, Nikon wasn't making their own crucibles....don't remember why, but did start again. At the time, quite a bit of the glass was made by Minolta in "raw" form to Leica, and Minolta was also making a small camera for Leica. > Glass melting is far from common these days and many buy glass blanks from > the larger manufacturers since it is cheaper than manking it themselves. > Canon never indicates they do their own glass manufacturing and not that it > matters, but I would not be surprised if they use Hoya glass too. They may now get it from Hoya, but at one time they did make it. Hoya, years ago, went after the market, producing glass to OEM specs, and as you've noted, they found it cheaper to buy from Hoya.
