Hi! I pop up here every 6-12 months or so. This time I'm thinking about the Nauticam WWL-C.

Currently I dive with a Nikon Z7 in a Sea&Sea housing. I also own (among other things) the 24-50/4-6.3 and a Z8.

I understand that the 24-50 and a WWL-C may take care of very much of one's non-fisheye wideangle photography, and in a convenient package.

Question 1: Can you use the lens more or less wide open with good image quality?

One thing I like with my 14-30 + Sea&Sea correction lens behind a large dome is that I can get decent corner results even at fairly large apertures. Would like to do that with a potential 24-50 + WWL-C setup also.

Question 2: Is there a good way to use the 24-50 with a Sea&Sea housing? It's not in their port chart. And, provided you can, is it possible to use it with the WWL-C and get good results?

The brute force solution is to switch to Nauticam equipment for my Z8 but that's quite the budget undertaking.

It might be possible to change out the lug ring on the Nauticam port for the S&S lug ring and use it on the S&S housing. Not all Nauticam ports have a removable lug ring and then you have to work out if the port length is still correct on the S&S housing. There will likely be differing depths of the camera flange in the housing between different brands. The WWL-C can only be attached to the Nauticam bayonet adapter which requires the specific geometry of the Nauticam ports m67 thread with the two cut outs. I believe it can also be fitted to Isotta ports which use the S&S mount. Lastly you'll likely need to 3D print a zoom gear. All do-able but requires some data to sort it all out abd some fiddling,

Hm, it does sound like while using WWL-C on my current housing might be theoretically possible, I probably shouldn't. I'm not much of a fiddler.

the fiddling is trying to work out which flat port will fit the 24-50. You could ask if anyone has made a zoom gear for the 24-50 on S&S, that would be the fiddly part if you can't borrow someone's design to get printed. Switching to Isotta might also be a possibility to use the WWL-C

Hi

I was in a similar situation when I bought my Nikon Z6iii last year. I was reluctant to spalsh out major cash on an all new Nauticam system to support this combination and in the end it was a fairly major job to convert my old Anthis Nexus housing (ex Nikon D7100 - D7500) and port to fit the Z24-50 and WWL-C. I am a compulsive fiddler and have a lathe and cnc mill amongst other toys but it was still a major task. Suffice to say that it can be a challenge to get the bayonet adapter fitted to a third party port and also ensure that you do not get vignetting with the WWL-C and clearances. . . but I can confirm that it is possible with some systems. Attached pics of housing with home made port with integrated bayonet adapter . . . not a job for masking tape and bluetack.

I will post a fuller story of the conversion .... one day. But I absolutely love the rig and the WWL-C equals or betters my old Tokina 10-17 and 100mm dome. As a happy snapper the abilty to go from 130 degrees to half macro (using a macro wet lens) during one dive is great. Many 'serious snappers' will disagree, but for me the flexiblity is great and worth the 300 plus hours of work involved . . . that is another story . . . Find yourself a local hobby machinist and present the problem and see if they rise to the bait.

Excellent work @JohnN

Very impressive!

Amazing work indeed!

I look forward to read the entire story on a new thread or even an article.

Thanks for sharing

Coming from DX and went to a Nikon Z last year. Shoot almost only WA of various types and shapes, my workhorses were the Tokina 10-17, a Sigma 10-20 and Nikons 10,5 FE in Hugyfot housings behind domes of different sizes. Went to Nauticam much due to them being inventive with water corrected optics.

The wwl-c and 24-50 is a great set-up and it’s very capable. Much better than any rectilinear zoom in a domeport that I have seen. Much sharper all-over. Nimble and easy to handle. The best for travel. I’m not sure how difficult it is or what the end results would be if you adapt the wwl-c to other housings, so can’t help you there. Previous poster seem to have done a great job with an Aquatica housing. Myself would not be able to pull that off—ymmv.

Being in Sweden (?) you should really reach out to and have a chat with Magnus Lundgren @Underwater Exposure in Malmö, he has a ton of experience with various set-ups, wet optics (shoot Sony atm) and is very friendly.

Wow.

I think the degree of difficulty varies significantly depending on which manufacturer you are dealing with. The fundamental problem is attaching the Nauticam bayonet adapter to a flat port that you can use on your housing system,

I believe that Marelux ports can accept the Nauticam bayonet adapter. You would need to work out if they offer a flat port of the right length.

Isotta offer a flat port which will accept the Nauticam adapter and they include the 24-50mm in their port chart, it takes the H63 port. The Isotta ports will fit directly onto S&S housings without any adapter.

I had a look at the S&S ports and looks like they might accept a Nauticam bayonet adapter, but the range of port extensions is quite limited. Nauticam port for the 24-50 is 16mm shorter than the Nikon Z 50mm macro while Isotta have a 20 mm difference in their ports. S&S specify the Macro port 15 with 20mm extension ring, so the Macro port 15 might work with the 24-50.
