I have a mixure of Hoya and Tokino filters, filters from both manufacturers are as good.
Think about it this way: A lot of devices, be it electronic or not, are made in China, we are using them day in day out, and never know or feel it, until someone told us that "this is made in China".
Let's change our perception. If China can also have their own satellite, and have the astronaut up in the space, do we still need to doubt the quality of their products, despites a lot of "fake" products that we heard or even buy from the great country?
