The above lens design is for a 58mm f/0.7 full-frame mirrorless lens for Nikon Z-mount. I believe this is a third-party project and I am not sure if it will come to production. Stay tuned for additional information.
Nikon has mentioned on several occasions that in addition to other benefits, the large Z-mount is capable of supporting lenses faster than f/0.95.
