Light transmission is one thing, but resolution is another. One of the things I've enjoyed about the Conquests is their ability to resolve detail better than the Leupolds I've compared them to. No,there's not a big whopping difference, but there is a difference with the advantage going to theZeiss and I can clearly see it when I look through them. Thisis definitely helpfulwhen you're trying to judge antlers against a backdrop of limbs and trigs roughly the same color.
