Hi everyone, I’m having my doubts about what 4“dime to buy for my Sony+Tokina10-17 with Adapter.

From the Nauticam Portchart their minidome works just fine.

A User is selling a Zen minidome which might work, but I’m not that sure about it.

Help is appreciated.

Best Regards

The Zen domes have some variations so you need the right version. I assume you are looking at adapting to an APS-C Sony and your housing is N85. From what I understand you need to add an N85-N120 adapter and they currently list the 60mm adapter #36204 for this specific purpose. The way Nauticam does these adapters is that installing the adapter and the Metabones Sony E to EOS EF adapter you then refer to the Canon EF port chart and use the ports/extensions specified there. Usually you can use the Nauticam Canon zoom gear for that lens and you zoom with th eknob on the N85-N120 adapter.

The EF port chart lists the Tokina 10-17 with a 10mm extension and 140mm dome. The Zen port chart lists the DP100-N120T for use of the Tokina 10-17 on Nauticam and this has the required extension built in. If you look online you will see quite a few variants of the Zen 100mm dome with varying extension built in. From the Reef photo website you can see all of them listed.

The DP100 N120NCR is for Nauticam with the Canon 8-15 with 30mm built in extension

The DP00 N120 T is for Tokina 10-17 with 10mm in built extension

Others are for Aquatica, Nauticam with 10mm nikon fisheye etc.

Also I moved this into Photo Gear and Technique.

Thanks very much Chris, this helps a lot.

Only with your info it’s quite clear that the Canon one then will be 20mm to long for my setup.

You are right I’m having a Sony APSC on Sigma MC11 adapter(4mm) shorter than the meta ones.

Not lucky this time will have to buy it new I Guess.

I would also suggest you confirm the port arrangement with Nauticam. They used to have a line item on their Sony N85 port charts for the correct N85-N120 adapter and then refer you to the Canon EF port chart, but that's not on the current port chart. I can't remember for sure but I thought it was a bit shorter than 60mm to use the Canon port system.
