#1 Yes Nauticam has a DSLR housing to Subal type III adapter.
#2 The minimum focus distance is the same with all of the ports. The only difference is that the 3.5 dome can get a little closer than the 100mm (about 11mm) and the 100mm a little closer than the 4.33 inch (about 10mm).
#3 I have owned glass ports for over fourth years and 1000's of dives. To date I have never damages and scratched any glass port or glass (Nikonos RS/2,3,4,5) lens. In fact I had my old Zen DP 170 d85 port glass put into my new DP 170 d85 II port mount because the glass was on backorder and it works fine. You can see the review on that port in the September 1, 14 issue of UWPMAG.com along with a review on after market 3D printed gears for Nauticam housings.
