Zeiss, like many "Euro" glass companies do in fact have Chinese optics. Many of them have the lower price class that is 100% Chinese. With Zeiss it is the Terra line. This is true for Minox, Meopta, Kowa, and many more. That Being said, IMO Vortex is greatly over-priced as a mostly Chinese optic. I have explained in the past that many of the products are no different than other brands but with different trim. I am not into spending a lot more on something to get a no-fault warranty but to each his own.Zeiss in the same lower category as vortex and leupold? Not even close dude. Especially if you’re talking Binos and spotters. You’re talking high end German glass vs Chinese.
