In Topic: D850: Nikonos RS 13mm conversion or Nauticam WACP?

11 January 2018 - 04:25 PM

@DocTock: thanks a lot for the advice! Which port are you using or is the Nikonos used as a port? But how is then the connection to the camera? Do you have a photo how this looks like? Lots of questions but thank you for every piece of information!!!

Regards, Sascha

To the OP @oneyellowtang - the advantage for me to the RS conversion is it allows me to carry a full macro and WA kit in my photo-backpack.





The Nikonos RS lens is a port with a lens. 


In the image below, you can see there is a dark metal ring between the Nauticam housing and the RS lens (dome portion).

That is the adapter (has o-ring on inside) that is needed for this Nauticam - RS solution.


To attach the lens, you first mount the adapter to the housing and the camera to the housing.

Then you attach the RS unit (it has it's own o-ring) to both the housing and the camera body at the same time.

Sascha -


I managed to source a Nikonos 13mm RS and sent it to Andrej Belic (abelic.net is his website) in Germany (or Austria ?).

He has access to the pieces/ technician to be able to change the internal lens so that it will communicate fully with a modern DSLR - I shoot Nikon D800 in a Nauticam housing.

He also has the additional piece of metal that is needed to interface between the lens and the Nauticam housing. 


For me, the biggest issue (after sourcing the lens!) was dealing with shipping from the USA to Germany and back. That should be far less of an issue (and export duty cost) for you.

Ken -


Thanks for fixing the links and I always really enjoy reading your narratives!

In Topic: Best Vacuum System for DSLR Housing

29 November 2017 - 04:51 PM

I'm a big fan of the KISS (Keep it Simple cuz I'm Stupid) school.


I use the Nauticam built in electronics (Nauticam housing junkie and now too many ports to switch) - the led fit where they are supposed to, the test point is easy to check, the battery is a very common coin type.

However, I use the Housing Sentry port as my point to provide vacuum. It's now on my second housing, and if the money tree takes root in the backyard, I'll put it on another housing (D850 looks so attractive!)

I like using a brake line fluid tool (may even be able to find one in remote corners of the world if TSA is kind enough to damage the one I've packed), and there's something comforting to me to be able to get a "quantitative" value as to how negative I've made the internals, plus I like how the pieces physically lock together when vacuuming/ releasing.

That said, the biggest concern I always have is that I will lose the little metal adapter that hooks to the port. A "smart" UW photographer would buy a few spare, but I never said I was smart...



Honestly, with all the options these days, the "best" system is the one you can easily learn, easily service, and actually use.

In Topic: New TSA rules and underwater strobes

19 November 2017 - 01:13 PM

I just travelled to Mexico and back to the USA with a photo-backpack and small rolling bag both stuffed with my housing, strobes, camera, computer, ipad, lenses, etc.

I can report that at both inter-Mexican flights and on return to USA the only "new" request was that I take my camera out of the bag and put it in a bin - just like my computer.

NO other lenses, strobes, etc were specifically removed.

I was requested on 2 bag checks to simply open my rolling bag so they could look at the housing and my octo/ reg directly - nothing was removed from my bags
