Now I get it: your Zen port goes right onto my housing! And I assume I would need the extension ring also, correct? Any guess what the shipping would be from Perth to San Diego, California? And is the dome scratched or damaged in any way?
That's correct, you would not need the Nauticam to Subal Type 3 converter and cost for dome port and extension ring would be US$355.
Price includes hard and soft dome covers and rear cover.
The extension ring is needed for use with the Tokina 10-17 fisheye.
Standard airmail delivery by Auspost with tracking and 5 business day delivery (estimated) would be US$40
The dome is in good condition, no damage or scratches.
If you plan on using the 10-17 on a Kenko 1.4X teleconverter you will need a 33mm extension ring. I have one available that you can have for the same price as the 15mm extension ring, US$50.
