..at least, when it comes to their scopes, that is.
I never used many Nikon scopes — from memory, I only ever owned two — and I don’t think they were ever a force in the scope business, so this doesn’t strike me as big news. I suspect that Nikon weren’t making much money in that department, despite their price premium over other brands, and as their camera business is probably under strain because of the ubiquity of phone cameras, this seems to be purely a business decision.
That said, I would point Loyal Readers to the Nikon Black FX1000 model, which I have used before, and which was excellent: clear, rugged and easy to use in the field. Consider these two: 4-16x50mm and 6-24x50mm (don’t necessarily buy right now… just monitor their prices in the near future and if they dip substantially, buy either of them without hesitation).
