fluorite! don't forget that! for that kind of pricing,
If you read the website carefully, they never mentioned the glass is crystalline fluorite (Calcium fluorite, CaF2) but rather ED fluorite/FPL-53 (a.k.a synthetic fluorite). Conclusion: they are using the same glass for ED80, ED100, or ED120, Pro or No Pro. It's just marketing, they know amateurs are obsessed with the word fluorite, but we know better :wink:
