I also have the 4,33" Port but it´s to small for half/half .
There is the 7" ZEN Glass Port and it´s to heavy and expensive.
Is there something around 6" and Acrylic?
Saw an Fantasea or Sea&Sea Port but did they fit on an Nauticam N85 Housing?
Wish i coud get an Nauticam 6" Port on this System
Any Ideas?
Thx
If you're looking for a rectilinear wide angle solution, I would recommend the 10-18 zoom with the Nauticam 7" acrylic. It's a much better lens than the 16mm with converter, and the dome gives a good solution for over/under if that's what you're after (and I get what you're saying about the 4.33" in that regard). In case you're not on Nauticam (if not why not?! [emoji14]), there must be other solutions for a compatible dome.
The problem with rectilinear is that especially at the wider end, and close in, it can stretch perspective rather nastily. Equally, you can have some fun with that, but it just doesn't work for CFWA - for that, you need fisheye.
