That's exactly what i used. If you are interested i can set you up with the port itself and you can insert the glass. If you know the height of the adapter we can figure out the required additional extension. You will need the distance from the mounting ring on the camera to the housing port base. If it's different from Nauticam we need to account for that. Message me if interested.

I once charged a buddies Sola with another similar spec charger on a trip to Indonesia. To make contact i made a "connector" with paperclips, a wine cork, and rubber bands. 😃

Interesting. Does the 70-180 zoom internally? That seems like a cool option. I will look into that!

What glass do you have? For my Olympus dome I think the diameter is 103.85 mm and I used a 103x 3mm oring that cost a few cents. If there is a Subal to n120 adapter, that would be all that is needed. I can make the port any length or just add the proper extension.

For compare and contrast purposes, here are a couple of images from earlier in the week with a standard 60mm Nauticam Flat port.

I dove the Curved Glass port with the Nikon 60mm & Nikon Z8 lens. I put the port on a 20mm (19 really) port base and connected to a 40mm printed extension ring. Everything worked great! Local visibility is not stellar right now but a lot better than earlier this week during a heat wave. I dove a Seattle muck diving site on Alki Beach and found it to be overrun with giant nudibranchs feeding on Sea Pens. Here a few sample photos: Nikon Z8 w/Nikkor 60mm lens, Curved Port, f14@1/200s iso400 Backscatter Atom strobe & snoot + BS MF-2 Nikon Z8 w/Nikkor 60mm lens, Curved Port, f5.6@1/200s iso80 Backscatter Atom strobe & snoot + BS MF-2 Nikon Z8 w/Nikkor 60mm lens, Curved Port, f6.3@1/200s iso100 Backscatter Atom strobe & snoot + BS MF-2

I ended up making a 20mm version of the Curved Glass Macro port and dove it tonight in an empty housing. Took it to about 80 feet in some of the worst, chunkiest, algae snow storm visibility I have every seen. We had record high temps and lots of sun in Seattle this week which leads to algae blooms. >sad< Less than 1 meter of visibility with all the snotty bits in the water. Still, the port held and worked perfectly. Next up is a proper dive with a camera and photos!

Welcome to WaterPixels. I am also in Washington State, here in Seattle. Both are great communities full of avid divers and photographers. Look me up if you need a dive buddy!

When I was using Eneloop cells, i would buy a new set every year. I was doing about 100 dives a year at the time. I used two sets of 8, so replaced one of the sets every year. A few years on now, most of my old Eneloops won't consistently charge anymore even for use around the house in remotes, thermostats, etc

So much for the conventional wisdom that AA batteries are superior to LiOn because you can buy them anywhere... For what it worth, i used a pair of 4XAA chargers that are USB-C PD powered. Redundancy and no issues with local power supply. Carry a 60W USB brick and run all chargers off of that

Is that a printed ring holding the dome on an extension ring? Subal maybe? I considered that but decided to just print the whole port a single part. If there is ever a need to use to curved port in a more diverse set of configurations I could make a 20mm ring holding the dome. I reprinted overnight and am getting ready to test this out.

It only took a couple of minutes to insert the o-ring. I made about six test prints to fine tune the fit. Too loose, still loose, too tight, just right. I made it snug enough that it was not impossible to place the o-ring. We will see how well it works in the water soon. I built in a provision for a locking ring outside the glass to secure it a bit out of the water. Now the original Zen dome I could not push out the glass by hand. I had to pluck out the o-ring with a steel pick. My dome i can push out by hand, so it is not as tight but hopefully good enough.

Yes, that looks like a problem! My extension ring design has that lip but i didn't (think) i needed that extra diameter for the port. I will add that back into the design!

Yes. It was from a Zen Underwater WA-100 dome port for Olympus 9-18mm. Cost about $200 on ebay. The actual glass rim diameter was 103.85mm. I bought 103mm x 3mm 70a orings from McMaster Carr. I got about 5 orings and used one up repeatedly using it to test fit and installation techniques in draft prints of the top of the port.

Great idea! Absolutely upload it to Makerworld. I'll try it out, very clever idea.
