For the Tokina 10-17mm, do I have to use the extension ring with the DP-100-S4 to account for the body of the lens and to get accurate optical placement?

Yes, you need extension ring 13mm to get it in right position for the best resoult.

For which housing?

 

I have a Zen DP-100-S4 (Subal) that a friend wants to try out on his Nauticam ND7100 housing. He has the adapter from Nauticam but I have no idea what ER to send him as well. Any ideas?

Then he need to measure it with lens and manually put port in front till he not see vignetting. Then measure distance ( that empty space) from housing to the port. this dimension will be dimension of ext ring that he need.
