This Sea & Sea port adapter allows Nauticam N120 port with the removeable locking ring to be converted into a working port on all Sea & Sea DX housings and Isotta housings with B120 port connection. To make the conversion, back out the 15 mounting screws remove the existing Nauticam port bayonet ring and replace it with this Sea & Sea port bayonet ring. It’s that simple. $40 with free shipping in the US

I bought this lens back in 2019 as a backup to my Nikon 8-15mm Fisheye at the time. Now I shoot with a modified Nikonos R-UW 13. As such, it has never been taken from the box, so essence it is basically a new condition lens.

Doing a little of house cleaning to reduce some of the photo gear that I just don’t seem to use. First on the list is a Nauticam 45° Viewfinder. I have had this viewfinder for over a year but have only used it 4 – 5 times. I am selling it because I still prefer using the Nauticam 180 straight finder instead. This finder is cosmetically in mint condition and perfect working order. Selling price $600 USD, buyer pays shipping from Florida. Second on the list is a Nauticam N105VR-F focus gear for Nikon AF-S VR 105mm F2.8G IF-ED Macro lens. The lens gear was used one time and put away in the original box it came in. Sale price $95 USD. Buyer pays shipping from Florida.

Do you already have any ports for a Nauticam housing? If you do, it's already settled.

Nauticam now has info and photos of their new FCP on their website -https://www.nauticam.com/collections/water-contact-optics-for-nav/products/n120-n100-fisheye-conversion-port-with-integrated-float-collar-fcp-170-deg-fov-with-compatible-28mm-lenses Looking at the specifications for it: Size - Outer Diameter x Length (port mount to front) 198 x 136mm / 7.7953 x 5.3543 in. Weight in air - 3.2kg/ 7.1-lbs. This is a horse of lens compared to my R-UW 13 setup (main lens body and port) weigh a mere .9kg/2-lbs. Fortunately, the FCP does not require an extension ring with the NIKKOR Z 24-50mm f/4-6.3 Lens. While it might be something to consider if / when I should decide to go to a Z8; if you are O.K. with dropping $ 6,941.00 USD on it. For me, the option of having my R-UW F mount converted to a Sony E mount and adding a Sony E-Mount Lens to Nikon Z-Mount Autofocus Adapter is looking better and better.

As far as I am concern, the MonsterAdapter LA-FE2 is still vaporware as it is still not listed on their own website nor is listed on any the retail outlets like B&HPhoto or even Amazon.

I have been using a Seacam modified Nikonos R-UW 13mm with my D850 for about three years running now. So far, I have not found any wide-angle lens behind a dome port underwater to be anywhere close to its equal. Having looked at both Nauticam new FCP as well as their WACP C water contact lenses, they strike me as neither that compact, nor lightweight enough to make them as ideal for travel as my RS 13 setup. That said, one of the primary setbacks with the Nikonos R-UW 13 is that the autofocus is driven by the earlier Nikon F screw drive system used in AF-D Type lenses up to 1987. Back in November 2023, MonsterAdapter announced that it was developing a new LA-FE2 Nikon F mount to Sony E mount electronic lens adapter with both aperture and autofocus capability built in through a new dual motor that would also drive traditional Nikkor AF-D lenses. The new MonsterAdapter LA-FE2 was expected to be launched with price and more detailed information at the end of 2023, but as yet (Jan 22, 2024) it has yet to be seen. My question is, if it had come be, would it have worked on my R-UW 13? One the things that I have found with lenses modified by Seacam (perhaps my case only) is that the lens will not properly interface with my D850 with when I attempted to use it with the Kenko TELEPLUS HD Pro 1.4x DGX Teleconverter which is rated for Nikon AF-D types lens. Autofocus works, but nothing else. Just Error for Aperture, metering, and shutter. Fortunately, I found no need to rush into the mirrorless camp as I see little outside of video capability providing any great advantage for shooting stills. If I were to make the change to mirrorless, the most logical option at the moment for migrating that lens over would be to have the optics retro fitted into a Sony 50mm E mount mirrorless lens. This of course would be contingent on the modification would provide full functionality (correct aperture control and auto focus) with a E to Z adaptor on a Nikon Z8.

Another Wetpixel refuge.
