A little over 20 yrs. ago when I was working in the business, I had the opportunity to make hands on comparisons with many different one's, and Steiner was horrible compared to other optics considered as top shelf glass, but they were sure priced up there with the good stuff though. But I don't know if they've changed their product or come up with a better concept, but back then they were no better than a $30 pair of Bushnell.
I also stopped to talk with a G&F guy a few years back that was carrying some Steiner's issued by G&F. He asked to take a look through my Leupolds and was amazed at the difference. When I put his up to my eye's, besides being terribly heavy and having awful imaging, they actually caused my eye's to immediately feel stressed.
