Fluorine, fluorite…what's a calcium ion among friends. Actually, the 'fluorine coating' is a clever bit of marketing-speak…fluorine is a highly toxic element that's gaseous under standard conditions, so the 'fluorine coating' certainly isn't just fluorine. It's most likely a polymer of fluorine and carbon…but neither Canon nor Nikon want to say they're using fluorocarbons as lens coatings…![]()
Can't say I blame them. Consumers are easily swayed by words and phrases to which they have a predisposition. Note how almost everyone drops the "RP" from "CFRP" because everyone likes Carbon Fiber but nobody likes (Reinforced) Plastic.
