Vlad, first you are making a comparison that is not relevant to the wine story to which you refer. In that test they used the same wine with a different price on each bottle. In your analogy you are not comparing the same product with a different price tag, but two entirely different products. As for the vitriol and calling Leica lens users chumps ...it is both wrong and inappropriate. Your argument is exactly like the selling line of a local used car dealer. The used car salesman claims that their nicely detailed cars are every bit as good as a new car (regardless of the age) because : "If you can't see the difference, why pay the difference." I think all of us would agree that determining the value of anything goes far beyond external appearance.
