Here is some interesting info from Gale McMillan, a guy that has been in the optics business for a long time:"Just for the record Nikon doesn't make their scopes or lenses. They are contracted to the lowest bidder. The last I heard they were being made in the Philippines I think. I buy lenses from the same manufacturers as most of the Japanese manufactured Scopes so I feel I can speak with first hand experience. Lens are polished to a standard which is the number and size of digs and dings that are not polished out. Then they are coated to aid in light transmission. The better lens are coated with a 4 layer coating and all use the same formula. The glass types are dictated by the computer designed lens system and the flint and crown glass all come from the same areas and the same computer design programs are used by almost every one in the industry What I am saying is while you may think one is better than the next. The only difference between a Leupold, B&L Simmons or any of the rest of the scopes that use Japans lens is the amount of quality control The importer is willing to pay for. When it comes to mechanical design only the American companies design their own mechanical systems. All Japanese scopes use nearly identical designs so there is very little difference. The big difference is where the importer wants to fit in the market place and what he is willing to pay for. If you stay within the same price range it doesn't make much difference what you buy if it is an import. I would pay more attention to which company makes it as that is the big difference. And one last comment. The scope companies don't polish their own lens, they buy them from lens manufacturers and price dictates quality.I have been in the lens factory when the buyer for one of the best known European scope companies was there on a buying trip so the name on the scope doesn't mean a thing on where the glass comes from."\"All newer scopes are more than adequate lens systems in them. Most scopes have Pacific rim countries lens in them and other than the Q.C. on each there is little difference. What you have to realize is that the quality is the degree that the manufacturer is willing to pay for. My feeling about Ziess is that they have mastered the elimination of stray light which gives their scopes a better color than most of the other makes and this gives the impression of being brighter and better. Keep in mind that most of the lens are made of the same types of glass and the same coatings so the only difference in the lens is how well they are polished as determined by the dig and gouges specification and the exactness of the curvature of the surfaces. The prescription of the systems are now calculated by computers using the same programs. Doesn't it seem logical that a company that retails its product for 1500 dollars would spend more on Q.C. than a company who sell their product for $500?"
