I doubt you could tell the difference between different assembly countries of the same model.
If you are using electronics for work or home, you already depend on Chinese assembly. By far the largest manufacturer of populated PC boards is from China, one reason manufacturers go there for subcontracting, full manufacturing or component sourcing is because they have the highest tech automation, due to the very high volume of board production, they can afford to keep on the leading edge of high volume pc work. No one can compete, not due to labor costs, just how much hand labor is involved in your camera, computer or auto electronics sub-assemblies? Not very much. Human could not do the precision work with as few of errors as modern factory robotics. Consumer electronics, including our cameras are much more complex yet more reliable than ever. A camera like the D7000, if not assembled by robots would be much less reliable, less precision and monstrously more expensive. Nikon makes high end cameras and lenses in Japan for a number of reasons but one it that they have production capacity that fits the demand. When everything was built in Japan, the market was tiny and their production facilities could produce them. Enter the new accessibility and ease of use of modern DSLRs and suddenly they need production runs in the millions. Who has that capability? China. If there was demand for 1,000,000 D3s's, they would make them in China. Right now, like it or not...frankly I do not like what globalization has done to unique cultures and local control.....we live in an era where we are totally dependent on products and subsystems from many countries some might not like for political or religious reasons, founded or not, but we really do need China and other former cold war opponents. You can't drive a car, watch TV, eat from a grocery store, buy a house with a mortgage, use a cell phone, fly in a plane, etc without using services from other countries, primarily China. At one time there were two self contained countries, the US and USSR. Neither one is self contained anymore so that means every country on earth is depended on products and services from other countries. When was the last time you were in China? Do you know how much things have changed there in the last 20 years? Stan St Petersburg Russia
