Thanks Larry very interesting!
If you still have a zoom ring from another brand that worked well, Nauticam makes an adapter gear that sandwiches them (at least the Sea & Sea or Nexus). You might check it out, as it solved me having to buy all new rings for my D500 when switching from my MDX-D300 to Nauticam NA D-500. It's only about $125.
Have you bought such equipment for the 10-17mm tokina specifically?
