Here in Nuuk someone is offering a NIKKOR 500mm F4.0 P ED-IF for sale. He wants about USD1K for it, and I wonder if that is a good deal? I have the 80-400mm, but that of course is an entirely different beast. I am using my 80-400mm with the TC14E II, but I think the f/stop is around f/8 @ 500mm, so a 500mm f/4 would be a significant improvement.
And, pardon my ignorance, but how would this perform on my D800 in regards to focus? It is not an AF lens, but the D800 has the focusing capabilities does it not? I believe with a P lens, I have to focus manually, but I can use the >o< AF indicator in the viewfinder for aid. Also, it should have the chip that enables compatibility with my D800???
