Available now at Leica Store Lisse – the rare Nikon Fisheye-Nikkor 14.3mm f/4 lens for 70mm cine cameras (taken from their Facebook page with permission). This lens is so rare that even Google doesn’t have any information:
“The lens was made originally for Disney, with plans to use it for a futuristic film and theater viewing with 360 degree screens. Produced by Nikon, the lens is capable of covering IMAX 360 degree film cameras at 70mm film. The legendary, elusive and regularly discussed Nikon 6mm f2.8 is considered to be the holy grail of (fisheye) lenses. Considering this lens is one of a kind vs the dozens of copies of the 6mm, features 70mm coverage vs 35mm of the 6mm, has a similarly ultra-fast aperture scaled up to 70mm, you can begin to understand the significance of what we have on our table today. With a bit of professional engineering this lens can be adapted to many modern cameras, such as Leica S or Hasselblad XCD. Its speed of f4 (which translates to f2.8 on 35mm) can be considered ultra-fast within its exclusive class. It’s just a marvel to gaze into this lens and get lost in the glass.”
For scale reference, here is the Leica Noctilux 50mm f/1.2 next to the giant Nikon Nikkor 14.3mm f/4 fisheye lens:
