Vortex has not figured out how to make good glass yet period. Nuff said lol
I'm a firm believer in YOU using whatever makes YOU happy. But to say that Vortex doesn't make good glass simply isn't true. Actually, I don't know that Vortex makes their own glass or contracts it out.
I once sat on the front porch late in the evening with my father in law comparing his Swarovskis to the new Vortex Razors I had. We passed them back and forth looking at different objects at different distances. The only noticeable advantage (and you really had to look to see it) was the Swaros were crystal clear all the way to the edge of the lense, whereas the Vortex lost clarity right at the edge. Neither one of us could see where the Swarovskis were $2000 better than the Vortex.
