I don't own many scopes, but have looked through many of them, including big European names. So far, the the best glass I ever seen is trijicon. I bought this scope from my coworker, it was new old stock, 4x fixed mad by only 32mm objective. the clarity and contrast are breathtaking. I can see details of small objects in thick, monochromatic brush better than with much higher mag and larger diameter scopes. Don't know because it is fixed mag scope or because intrinsic quality of the glass is so high. Another scope that comes close is Zeiss Diavari, but the clarity and contrast still inferior to trijicon.
