For the first time since I can remember, Nikon has published any roadmap for their future lenses. The diagram above shows Nikon's future Z-Mount S-Class lenses. I have purchased the S 24-70mm f/4 and the S 35mm f/1.8 lenses for my Z7.
I have the FTZ adapter. However, the less I use it, the better. In addition, S (Superior) are Nikon's best. I have no intention of purchasing any future Z-Mount Macro lenses. The FTZ adapter is a natural tripod mount for my present four Macro lenses.
I plan to purchase the S 85mm f/1.8, the S 14-30mm f/4, the S 50mm f/1.2, and the S 24mm f/1.8, when released. Why the 24 1.8 when I already have the AF-S 20mm f/1.8 and the AF-S 28mm f/1.8? I will use the 20 and 28 with the adapter. If I do not want to use the adapter, I would have the S 24. With the latter, I do not need either the 20 or 28.
I would love to have the future S 58mm f/.95. However, it is rumored that it is going to cost ~ $6,500. That is too costly for me to spend on a lens. The other lenses that peak my interest are the S 70-200 f/2.8 and the S 14-24 f/2.8. I'm afraid that they will be comparable in price, size, and weight to their AF-S counterpart. Not only are they going to be expensive, but primarily too heavy for me.
