I have been experimenting with ultra-fast glass that can be mounted on a Nikon or Bellow for some years. Some examples are the Nikkor “O” CRT 55mm f/1.2 lens, The Noct-Nikkor 58mm f/1.2, the Repro Nikkor 85mm f/1.0, and so on.
My question is what other ultra-fast lenses do we know about that can be mounted on a Nikon F-Mount”
Any suggestions appreciated. Thanks.
