I do not need it. It is not immediately available, and neither are the lenses that I would prefer, but they are on the map. If I was miraculously given one with a small number of released lenses, Would I turn it down? No. Would I whinge about the size and weight? Yes. Is this a D3 moment? No We also got the D300. I bought one ( the D300 that is). Is this a D5 moment? No we also got the D500. I bought two ( and use both often). Is this a Z9 moment. No. we don't get a Z 90 for oiks like me. Being serious. Even 1" gives acceptable quality for most purposes,(So do phone cameras and the something or other Nikon 900 with one over two thirds sensors. Micro four thirds is better. APS C is better still. There cannot be the mirrorless equivalent of a D850. It would need the same sensor as the Z9 in order to get the AF performance.and that will be expensive for a few years. I suspect that Nikon is making a mistake in dropping DX.
