The way I read your OP is that you were wondering if the GE had always had HD (whatever that is) glass, or were there GEs without HD glass at the beginning, and then later on Vortex added HD glass to the GE line.
I think that's a valid question, which so far, has not been answered. If that was not the intent of your question, then I just read it wrong.
At any rate, ED glass (Extra low Dispersion) glass first appeared in riflescopes about 14 years ago when Deon introduced ED glass to their March scopes. Later on, other companies followed and also started using ED glass in their scope. Now, if your scope's literature does not mention ED glass or the words (low or extra low, dispersion) then it's not in there. ED glass is a differentiator and marketing will always latch on to a differentiator, or at the very least try to keep up with the industry.
I went to the Vortex website to look around and I wonder what this is:
- 35mm ASR (Aperature Stop Ring)
What is an "aperature" ? Perhaps they meant to say "aperture"?
