Based on these silhouttes, we can make projections about the upcoming lenses and their maximum apertures. Here is the detailed list:
Nikon Z 18-140mm f/3.5-5.6 DX – this is likely a rehash of its current Nikon F mount counterpart, so it will probably have the same maximum aperture of f/3.5-5.6. It will not be an “S” line, so don’t expect this lens to have any premium or weather-sealing features.
Nikon Z 24-105mm f/2.8-4 S – if the scale of the lens is more or less correct, this could be a fast-aperture f/2.8-4 zoom. I initially thought this would be an f/4 lens, but considering that it is taller than the 24-200mm superzoom and almost as tall as the Nikon Z 24-70mm f/2.8 S, it is unlikely that Nikon will make another standard f/4 zoom lens.
Nikon Z 28mm f/2.8 – judging by the small size of the silhouette, we can project this to be a small, lightweight, and very inexpensive f/2.8 pancake-style prime.
Nikon Z 40mm f/2.8 – another pancake-style prime with an f/2.8 maximum aperture.
Nikon Z 50mm f/2.8 Macro – it looks fairly small in the image, so it will likely be an f/2.8 macro lens.
Nikon Z 85mm f/1.2 S – although the lens does not seem to be as tall as the newly-released Nikon Z 50mm f/1.2 S, look at how wide the front element of the lens is. This will most definitely be a premium f/1.2 prime that’s going to be very heavy and pricey.
Nikon Z 100-400mm f/4.5-5.6 S – it is a given that this will be a variable aperture lens. And being an “S-line” lens, I expect it to be a solid, weather-sealed zoom for shooting outdoors.
Nikon Z 105mm f/2.8 Macro S – optically, this should be very similar to the current Nikon F 105mm f/2.8 Macro lens. However, the silhouette shows a very tall lens with a large barrel. Perhaps Nikon is planning to go with a faster maximum aperture of f/2?
Nikon Z 200-600mm f/5.6 – this could be very similar to Nikon’s popular F-mount 200-500mm f/5.6 lens but with 100mm extra reach. The lens looks pretty big in the image – almost as big as the 400mm prime.
Nikon Z 400mm f/2.8 S – Nikon’s “best of the best”. I expect this lens to be announced with a high-end Nikon Z camera body that is designed for shooting sports and wildlife (Nikon Z9?). It will be an exotic, super expensive lens for professionals. Expect new levels of optical performance for high-res cameras, and I really hope Nikon will design it to be lighter than the current Nikon 400mm f/2.8E FL ED VR lens.
Nikon Z 600mm f/4 S – this beast should be announced together with the 400mm f/2.8 S. We might see a “development announcement” first for the trio of 400mm f/2.8 S, 600mm f/4 S and the Nikon Z9 (or whatever the premium full-frame sports camera is going to be named). Either way, this is going to be a stellar lens for the Z mount. Super good and super expensive.
