All of the camera makers sell components to each other, but it might be unusual to sell a component that gives a competitive advantage. I've opened various cameras to see "Sony" printed on the LCD or other parts.

Nikon now uses fluorite in their supertele lenses (after bashing them as ‘prone to cracking’). I wonder if they make their own, and if so, they could be making them for Sony.

Canon may be selling flourite glass to the others, but it now also has Super Flourite glass.

Never mind the spelling, what is super fluorite?

No idea, there are fluorite elements, Super UD elements, but I have never heard of super fluorite....

Brush up on your facts: Lenses without fluorite are prone to cavities.

Lenses with flourite are more prone to have mold...

The town of Dumbsville wanted to promote dental health so they put flourite in the drinking water. The resulting paste didn't help anyone's teeth, but made the plumbers happy.
