I've read up a little on Japanese manufacturing techniques, and I don't think what you've said is very accurate. Japanese workers at most major manufacturers are as well trained as any in the world, and participate in optimization of manufacturing techniques through the "continual improvement" process. These techniques were so successful that they've been adopted throughout the world to improve manufacturing. Ford, for example, has become successful by wholeheartedly embracing the use of teams, quality circles, and the Deming method of quality control (which the Japanese were first to use widely). In this method a defective product is not simply "chucked" by an assembly-line droid, which is I think the image you presented; rather, the entire manufacturing line is stopped and the fault is analyzed and fixed. The chucking of defective product without further analysis was precisely the kind of practice that occurred in the quality control methods used in the West, and which got us into so much trouble in the seventies. In short, I think that while Japanese lenses may be designed to lower mechanical standards than Leica lenses, that isn't because Japanese workers "understand too little" -- it's because the company has made a decision that the right quality/price tradeoff is lower than Leica's. And for the market segment they're in, they're right - -- they own that market. - -Patrick
