The reality is you just don't know where all the components in your optics are sourced from. Point of origin. Some say I buy Leupold but Leupold doesn't make lenses and prisms. They source it from Asia like most everyone else.
Zeiss makes plenty of chinesium products but they do own or at least did own Schott Glass Werks. Swarovski and Leica spec out lenses and prisms and apply their proprietary coating on them but don't manufacture "glass", and it's doubtful they manufacture all the internal components either. We just don't have a say when we purchase because none of these companies are going to declare where point of origin concerning their products and what % is sourced from China.
