Maybe: S&S Z7 -> Nauticam Z8, WA

Again, thanks!

Turns out S&S doesn't have a zoom ring for 24-50. I guess I could see if my existing zoom ring would fit, though I'll have to wait a week. But without zooom ring, S&S is no longer an option. And yes it would theoretically be possible to 3D-print one but in practice, probably not really. And I'm given to understand that you want to be well placed with your lens för WWL-C. "It's probably about 20 mm" sounds shaky.

I do have a 20 mm extension, which could maybe see me over for using my existing macro port(s) on an Isotta housing. It's worth considering.

Also, I did find a Saga adapter to use S&S ports on Nauticam housing, but if the flange distance is larger on Nauticam than S&S it doesn't help much.

However. I did put one Nauticam WA package and one Isotta WA package together in a spreadsheet. Final prices will depend on the euro - SEK exchange rate, I've used 11.5 SEK for a euro now. Then I get

Nauticam: 89000 SEK

Isotta: 84000 SEK

Not much of a difference really. Mind you, that's with Inon 45 degree viewfinder, I don't know how much superior Nauticam's own is. It costs three times as much.

A macro port for nauticam would set me back about 5500 SEK more.

So yes, Nauticam is a bit more expensive than Isotta but not a big difference, and then I have a Swedish retailer. I'd say the omens indicate a Nauticam solution - either that, or do nothing and stay put. Well, I won't have to decide today. And I could investigare Isotta a bit more.

what basis are you using for that comparison? You should be able to use all your existing ports and extensions on Isotta, perhaps not on Nauticam. Is that quote for a full set of ports for both options?

The difficulty in explaining is hopping between two options . If you want to use the 24-50 on your current S&S housing is option 1. Option two is to go to a Z8 system either Nauticam or Isotta. .

Option 1 just email Isotta and ask them if they can confirm the correct port to use with the 24-50 on your S&S housing. You would need to print a zoom gear and there are a few places that will do this you could try:

Option 2 if you went with a new housing , again email Isotta and ask what is needed to use your existing domes/extensions with a new Z8 housing. You can buy all you need for the 24-50 off the shelf. I believe you should be able to keep all of your existing domes.

For the Nauticam option to make reusing your domes feasible you would need to source Nauticam lug rings for each S&S dome assuming they are removable, they used to be available but now discontinued. You would need to know the length of the Saga adapter if you wanted to go that way.
