Nikonos 13mm to Sony E mount Conversion
I have developed a procedure to convert the legendary Nikonos 13mm (the sharpest underwater wide angle lens) to Sony E mount by removing the optical elements from a Sony 50mm f/1.8 lens and replacing them with those from the 13mm. After the conversion the lens has native Sony autofocus and aperture but with the optics of the 13mm.

Additional Details
For the port I separate the 13mm front element/dome from the rest of the lens and attach it to a port I 3D print out of PETG. I am still in the process of pressure testing, but I expect the port to withstand 330ft/100m.

I am starting out with a port for Nauticam Sony N100 housings. I will add ports for other housings in the future.

It should be possible to use the converted lens on Nikon Z cameras with a Sony E to Nikon Z adapter, but this has not yet been tested/confirmed.

The conversion will cost $1000 USD. There is also the cost of the Sony 50mm 1.8 (~$150-250) as well as shipping (I'm located in Marble Falls, Arkansas, USA).
