3.5" nauticam dome and 30mm ring extension

[nudibranco]

I have now the beautiful 8mm FE lens with the 3.5" minidome....! went out on a short dive and the results seem fantastic.

Shortest focus distance, sharp even in the corners... so I am wondering ....
... with the extra 30mm extension ring, could the 9-18mm lens use the same dome???.
The 8mm lens will fit snugly within the 3.5" dome and it is about 20mm less length than the 9-18mm fully extended. So it should fit... Has anybody thought of trying this?

I never seen a Nauticam 3.5" port for the 8mm FE lens. Can you please provide a link for this port?

I got the idea for this from Alex Mustard on his writeup here
Olympus OM-D E-M5 - Page 15 - Digital SLRs/Housings - Wetpixel :: Underwater Photography Forums

Nauticam has it offered for the Panasonic 14mm lens only...
