Hi Guys,
There are so many options out there and I know so little. The are an endless list of optical lens material and when it gets to using a thick chunk of it for an aspherical lens then it can make a difference. What is worth using in a lens like this. Is glass the best thing but the most expensive. What's this PMMA stuff. And I know that with my hunting scope they are coated to improve their performance. What about lenses.

Probably a big question I suppose, but as said "I know so little."
