Why can't China fake it? What are the difficulties in producing lenses?

Shanzhai appeared for the longest time in the field of electronic products. The price advantage is to remove the cost of intellectual property rights and only calculate the low cost of electronic components. Moreover, many components are basically universal, and there are a large number of component suppliers.

The lens is different. Every shot of every shot is unique. There is no supplier for this, and it basically needs to be produced by itself. Moreover, the current high-quality lenses are all made of materials, coating technology and accuracy. In other words, even if you can get the design drawings of camera manufacturers, few factories can process lenses at a lower cost than the original factory according to the design drawings. Let the military do it, but the cost is higher than others' retail price and has no market value.

The essence of another shanzhai is to make it 790% similar with 1 ~ 20% money. As for the lens, 1% may not be similar to 50% of the money, so there is no fake unless it is pure fraud.
