Hello all,
I know many of you have been asking for this and I finally got around to making it - this is 3d printable adapter will allow you to attach the 35mm/80mm Nikonos lenses to your Sony E mount camera and achieve infinity focus.
For underwater only lenses (like the 20mm), you'll need a shorter adapter. I don't have that one made yey.
You can download for free from here: https://www.thingiverse.com/thing:6791948
Let me know if you try it!
