Stubblejumper, have to stop you there. Leupold gets there lens from several outsourced suppliers just from the same spec. Just a few months ago in Germany, I saw a Purchase Order on the table of the salesman of that company from Leupold. I couldn't get anymore details and can't be sure. They keep that info pretty tight zipped. They better or my company would have to break out the lawyers. Gov. Contracts would have a huge problem also. As far as quality, I don't know, I have used Leupold my whole life, and can't see any difference between the two. As far as brighter, according to a Optical reflection meter, it says no as far as a rep from Germany says. Anything past 94% transmittion is really hard for us mere mortals to see.

I say if you got the cash, you can't go wrong with Zeiss. It would be a toss up for me.
