First dome port

I am currently shooting M4/3 cameras in Nauticam housings with N85 flat ports plus water contact optics (WWL-1 and diopters) with the 12-50ez kit lens.

Although I'm happy enough with the WWL-1 I do wish it wasn't such a massive piece of glass to deal with. Also I find myself never removing it although I've just gotten the bayonet mount so that may change. I find myself frequently diving with the 12-50 just behind a flat port and wishing it was a touch wider. When I'm using the WWL-1 I wish it was wider still.

Which brings me to the question. I'm tempted by a dome and I see that Zen offers an adapter for Sea&Sea domes which seem to be available at less than painful prices. Does anyone have experience with adapting either the NX Compact dome 150 or one of the larger domes on a M4/3 in a Nauticam housing?

The use case would be wreck and CFWA plus occasional freediving.

Thanks,

Grant
