I'm debating if it can become my night dive lens. Seems like a great option for various night subjects if I don't want to go macro.

I started with NEX-5 and moved to Sony FF after A6400. I reviewed several lenses but for my personal use my go to lenses where Zeiss 50mm macro (75mm equivalent) and Zeiss 12mm (18mm rectilinear equivalent) for best image quality. This may sound old school but both are superb and under $500.00 each in the used market.

I can confirm that the Samyang 12mm AF f2.0 lens works flawlessly behind the seafrogs 6" dome port designed for the Sony 10-18mm with any of the a6xxx cameras. Especially with the glass dome port option, the corner sharpness is really excellent, and the whole package is quite inexpensive. It's awesome for reefscapes but definitely not the most versatile system out there in terms of focal lengths available. The 100º FOV is great IMO though.

 

I'll second the Samyang 12mm AF f/2.0 lens for wide angle on Sony APS-C. I use it on my a6400, in a Seafrogs housing and behind their 8" acrylic dome. I've been pretty happy with the results to date. 

 

I'm sure if you're switching to Nauticam someone could help with the correct spacers you need to fit it behind one of their domes. 

 

I threw some samples into an album here: Samyang 12mm AF f2

I'll add more as I get more.

Has anybody some experience with other size of domes with the Tokina I’m struggling to chose between a 100mm mini dome or something a little bigger as it’s the only one I would have. 

Yep, I’ve had the 100 and the 200. The only advantage I could ever see of the 200 is for over/unders. 
 

The 100 optically is just as good, is easier for travelling and better ergonomically for CFWA. 
 

If over/unders are essential then a 200 is very good. Otherwise, for me, 100 is best.
