WTB: Nauticam N85 to N120 50mm Port Adapter and 40mm N120 Extension

[Marsh 9]

Looking for a N85 to N120 50mm port adapter with focus knob and a 40mm N120 extension for a lens experiment. The likelihood it will work is slight and rather dim...LOL, but possible and willing to give it a try if I can find some affordable used gear. 

 

Send me a PM if you have one of these items for sale.

 

Cheers,

 

Marshall

I don’t think a 50mm port adapter exists
There are 34.7 41.5 47 55 60

FYI, the 50mm does exist: Nauticam # 36206 for Tokina 10-17mm Zoom is a 50mm length N85 to N120 port adapter.   When I first saw your reply I thought I might have one :-) 

Thank you for your concern.  I'll update my post to include the reference to he Tokina just to catch better attention, should one not be familiar with the length of the available ports. 

Cheers,

Marsh

I stand corrected anyway if you dont need the zoom gear you can combine anything you want

Yes, that is true and I have taken that into consideration.  However,  those two items would place the lens in the best optical position and keep the simplicity of two pieces of gear. Piecing it together with multiple units just makes it more complicated.  Moreover,  I used to shoot with a Tokina 10-17 and liked it when I was using a Canon housing.  I now use a rectilinear Zeiss 12mm which I prefer.  Still, it would be nice to use the Tokina again if I wanted to, but that's not the modification and lens I have in mind for this project. 

What I have works on N85, so unless I can find some affordable components for what I have in mind for the N120 mod, I'll most likely just keep using what I have. 

Appreciate the info :-)

What lens are you trying to house?

[Marsh 9]

The new Sony 16-55mm F2.8 G lens for APS-C.  I occasionally use the Sony 18-55 kit lens as a very light and minimal travel rig. It's dome has been modified to use as single dive rig for both WA and SM. I thought about replacing the kit with the new Sony lens, but I'm not too hopeful it will work: While on paper, it appears close to fitting,  whether it will  work optically is another matter, especially since it doesn't have quite as close a minimum focusing distance as the S18-55  kit. This will, of course, affect the domes virtual image. Nor do I know if it will play nice with my CMC-1 +15 close-up lens.  

I love experimenting with my a6500 system though and am willing to give it a try if I can get the components affordably. I plan to eventually purchase the G lens for surface travel photography.  I have low expectations on the success of this modification and feel the project will be on the back burners for some time :-) 

I currently use the Zeiss 12, the Sigma 16 f1.4 and the Sony kit in the 4.33  mini dome (lens are modified to fit).  I also shoot with the Sony 90G in a N100 port set-up.

Any further discussion on modifications and the above lens use needs to be through a PM.  This post is to procure the adapter and extension.

Thank you,

Marsh

Got the N85 to N120 adapter! Only need a 20mm N120 extension now.

Thanks,

No longer need any of the above stuff.
