I'm really sad to see this happen as well. I've been a Nikon user for 3 decades myself. Canon has always historically had better lenses and Nikon has had better bodies but lots of third party support. I do have some Nikon primes, but most of my lenses are made in Japan by Sigma or made in Japan or Germany by Zeiss. I have had exactly two lenses made outside of Japan by Nikon from their consumer line, and both were subpar optically compared to the Japanese made lenses in their pro line-up. It's such a stark difference, in fact, that I have taken to mostly buying used consumer lenses from the earlier auto-focus days (1973 - 1998) because these lenses are on par with the optical clarity of current generation pro lenses if cleaned professionally. You can usually acquire one for a significant cost reduction compared to buying a new pro lense and have it cleaned locally by the camera shop and get something really quite good. That's how I acquired my 600mm, 500mm, 400mm, and 300mm telephotos for birding, as well as my 50mm f/1.2 prime for general use. Seems if I add any lenses to my collection I'll be buying used or new from Sigma/Zeiss. I saw the shift happening already and had mostly already been doing that. I will say the new PF series pro lenses with fresnel lens elements are really great though. While I still have my older 300mm, I also got the new pro series 300mm prime from Nikon as it's significantly smaller and lighter weight, doesn't even require a lens foot and can be shot hand-held if you have a steady grip. I suppose I should start budgeting to acquire the 500mm version of the PF lens before they move production out of Japan as I find it unlikely I'd buy anything else that's Nikon branded for lenses. For shorter focal length stuff Zeiss is far far superior.
