There are quality things made in China, for example Apple has over 700,000 employees in the
Chinese factories turning out quality producsts. If they were not, they would not be the massive
company they are today. They have high quality control, and have direct control of operations and
all of the rest.
In optics companies it is much the same. The large companies have the same QC, company owned
factories, with nice results. Some names that come to the top are Nikon, Canon, and others that I
could include.
Otherwise, some sellers contract with Chinese companies, and it is different there. You pay for what
you get. Some China products are made "just good enough". If you have ever purchased a cheap
astro big binocular, you will know what I mean.
The story is the same, if made in Japan, you can depend on a good level of quality, all the way to
the very best.
China made optics, at least binoculars start at the bottom, and go to around the $500. USD level.
There are not any that sell any higher than that, that I am aware of.
