I know about the Nikonos lens adapter for the Nauticam housing for the Sony NEX. Could this new Metabone "Speed Booster" adapter idea be a way to get my old (and much loved and missed) Nikonos 15mm lens back to function FF and be a stop faster? How wonderful to have the use of that great lens again, although it is going to be all old skool manual..LOL

I am afraid it will not work. The nauticam nikonos adapter already places the Nikonos lens at the correct distance from the NEX sensor so it's image will be in focus only without additional adapters. The metabones adapter will do the same when used directly between the camera an the lens it converts (if they ever make one that fits your nikonos lens..) But then the combo will not be watertight, and there is not much use in putting an additional port around the 15mm+adapter combi.
It will work with e.g. full frame canon lenses, for macro this might be a good solution, if you can find a port that fits.

I just got the Sea&Sea 12mm f3.5 fisheye for nikonos fit to try on the NEX with the nikonos adapter. Will give almost the same field of view compared to the 15mm on full frame, only this is a fisheye...

Hello fellow Dutchman (I was born in Den Haag ). My post was actually a gentle nudge for Nauticam to consider. I think they could do it if they are able to get their hands on the Caldwell design optics that is inside the metabones adapter. Since Nauticam already has developed a working adapter to work for the Sony NEX 5 housing to fit the Nikonos mount, it would not be much of a stretch to think that it be able to fit the optics inside the Nauticam NEX-Nikonos adapter. I have shot the 12mm Sea&Sea and loved it. Just imagine to be able to have this lens full frame and it be faster at f2.8 as well.

There isn't sufficient flange back distance... Similarly, no speedster has been announced for Leica M lenses, which have a similar FFD.
