[QUOTE="Loner, post: 569643, member: 24560"] You seem to be of the impression that an infinite amount of light can be focused down to any size and passed through a lens with no additional loss. Not my understanding of light and optics. But I am not claiming it's a large gain by any means, I did say a little more light. And I really don't know if some of the 30mm tubes have any larger erector lens or not. They may have. But my swaro 3x12 30mm has a pathetic 39 moa of total travel. Nightforce can squeeze 100 out of the same tube. Looking through the scopes is a totally different animal. One is an enhanced bright picture and the other just another scope. Like you said lots of difference in glass and coatings. Even my USO's are not better than the Swaro in glass. I don't doubt a Zeiss would be any different. Making the erector shorter and ffp vs sfp would also play into how much elevation can be delivered. With a shorter erector the mechanics of holding it in place become more of a challenge and the physics in the optical design would be different as well. It would be fun to take a class from a scope engineer on all this stuff wouldn't it. I like the equipment as much as I do using it I think. ( microscopes are a great example of how badly light is transmitted through a small lens, look at the 1000x lens and without a bulb right behind it you see only grey. Much different in design and application so I am not sure if it's apples to apples) [/QUOTE]
