Just to be sure people are being realistic, I have seen the construction parameters of PF technology analyzed, and I was/am convinced that Nikon will never make a 600mm f5.6 PF lens, as the front element would be too large and the lens either front-heavy or just too big and heavy (and expensive) to be sufficiently appealing to people looking for hand-held portability. It's more likely they would try to concoct a 600mm f6.3, or even a 600mm f8, if they could bring the price of the latter down sufficiently. Canon is selling a lot of 600 and 800m f11 lenses, surprisingly, largely because these are so cheap.Nikon 600mm PF Z mount? that might get me to stay awhile.
I imagine the Z9 will have decent animal eye tracking before it is released. Add a 600 PF lens and that would be awesome, theoretically![]()
But no new PF lens is even hinted at on Nikon's Z mount "lens road map," so we can dream on . . .
