Nikon's currently published road map for Z lenses (as of October 2020):
- 18-140mm DX zoom (before end of 2021)
- 24-105mm S-Line zoom (before end of 2021)
- 28mm compact lens (before end of 2021)
- 40mm compact lens (before end of 2021)
- 50mm Micro-Nikkor (before end of 2021)
- 85mm f/1.2 S-Line
- 100-400mm S-line zoom (before end of 2021)
- 105mm Micro-Nikkor (before end of 2021)
- 200-600mm zoom (before end of 2021)
- 400mm S-Line
- 600mm S-Line
So, is this enough? No. Particularly missing in Nikon's Road Map are:
- Completion of the f/4 zoom cycle (missing 70-200mm)
- Telephotos that aren't zooms or exotics (e.g. 105mm or 135mm prime)
- Complete fast prime set (e.g. f/1.2 or better in at least 35mm, 50mm, 85mm; we're still missing at least one)
- Additional compact lenses (collapsing zooms, small primes)
- Any PF lens (Nikon made this a specialty and they're popular, but no Z versions)
- Any tilt-shift lens
