Question Is Tamron 90mm F/2.8 Di III (Sony) compatible with Nauticam?

[MrTW]

I'm pretty sure I know the answer but asking to reconfirm:

Anyone know if the new Tamron 90mm F/2.8 Di III MACRO VXD for Sony is compatible with any Nauticam port or adaptor fitting the Nauticam NA-A7RV housing?

I cannot say for sure. But you should be able to cobble together a solution, You would get a short macro port and with the right port extender, it should work. It would not have to be exact. Now if you want a focus gear for that lens you are probably out of luck. Usually Nauticam has solutions for the main lenses of the major lines like the 100 or so macro, a wide angle zoom etc. They usually do not support the secondary lens lines like Tamron, Tokina, Sigma etc. Sometimes they do but not usually.

Had a long talk with Peter from Scubapix and after taking measurements of the Tamron 90mm, it appears that the Tamron does (kinda) fit into the N100 Macro Port 105 for the Sony 90mm. There is about 1mm wiggle room as long as the measurements were accurate enough.

Only drawback here that this will not allow for MF since the focus gear of the Sony does not fit the Tamron.

It is very likely that Nauticam will come out soon with a focus gear for this lens. In the meantime one easily can make photos without - I am sure many will not order one at all...
=> regarding the long N100 Macroport 105, I regret that I have bought the long 105 macroport for my Sony 90mm lens. It would have been better to go for a short macroport plus N100 extensions instead to provide more flexibility and the the possibility to house more lenses...

Hi Wolfgang,

Would you have the Nauticam SKU's / item numbers available for the setup with the short macroport plus N100 extensions by any chance?

N100, type II (new style), Extensions are available with 30, 35, 40 and 50mm, as well as the old style extensions. Any combination resulting in idential (or close) length, e.g. Macroport 55 (SKU # 37123) with 50mm, should work...

Before buying the macroport 105, I asked both my local dealer and Nauticam whether the macroport 55 (SKU # 37123)/50mm extension combination would work for the Sony 90mm. The dealer responded first, told me it is incompatible and so I ordered the macroport 105. Later Ryan Canon from Nauticam contacted me and told me the 55 macroport plus 50mm extension is totally o.k. ...

=> Better ask at Nauticam before ordering a combination, but in principle they all should work well...

Thank you very much for the info!

In checking the two parts (N100 Extension Ring 50 II (SKU # 37433) plus N100 Macro Port 55 (SKU # 37123)) the total cost would run about $1,423 ($778 + $645 respectively) for both parts.

The cost of the N100 Macro Port 105 is about half that ($717) - aside from the leverage and flexibility adding other extension rings for different lenses, what other advantages do you really see in going the approach with two parts versus just one dedicated port?

The combination is more expensive, but as you state, you get flexibility (I cannot see another advantage than flexibility: housing of multiple lenses with one planport and different extensions (the extensions can possibly also be used with different domeports/wetlenses (e.g. WACP-C))...
In case one plans to house just a single lens (Sony or Tamron 90mm macro) this flexibility is certainly not required...

Before I was a Sony user, I had Oly EM1II and used it with both Zuiko 60mm and Pana 45mm macros with the (N85) 45 macroport. The 60mm just required an additional 20mm extension. Much better than to carry around two different macroprts (macroport 45 plus macroport 60) - really a smart combination...

At the moment there is almost no choice for different macro lenses with Sony FF. I plan to use my SOny 50mm f/1.2 lens with extension tubes for macro with bokeh UW. In addition, I hope that Sony, or another company, will come out with more macro lenses with different focal lengths (e.g. 50mm, 120mm, 150mm) and more than 1:1 (o.k., I am a dreamer). When there is more choice, very likely I soon would come to the limitations of the 105 macroport and will have to purchase (and carry around) another one..
Also, in case one plans to use WWL-1 (I have WACP-C with 30mm N100 extension), one could try to make a configuration with the planport for WWL-1 and house the macrolens within the same port. I think a 45mm N100 planport is required for the 28-60mm/WWL-1 combo, so altogether 60mm N100 extension should do it...

I am also a fan of leverage and keeping things flexible even though that might come at an initial and upfront invest.

So, I therefore reached out to the retailer currently putting together the A7RV Nauticam rig to see if it would make sense to go the two-part route versus the single N100 macroport 105.

Since I am only after macro for now the retailer highly advised against stitching the two pieces together as the N100 should work natively for the Tammy 90mm (or Sony 90mm). His reasoning is that added flexibility generally always comes at the cost of image quality and that the single piece here will serve me better than the potential flex going forward with the two parts.

Even though the retailer could have sold me another part for several hundred dollars more he talked me out of it, which I highly appreciate. Now, should I change away from macro one day I can totally see the need to just swap things out at that time and being in the same position you described earlier on in your post.

On a different note: I am also waiting for a new line up of macro lenses. I finally got rid of the Sony 90mm and got a Laowa 90mm 2:1 MF for surface photography. The Laowa quickly taught me my limitations - Great and fun lens but extremely difficult to operate and I therefore also got the Tamron 90mm, which is actually pretty good for macro surface with a diffusor. I'm curious to see how the Tamron 90mm behaves underwater when I get to test it all out.

You should change the retailer, as he has no clue what he is talking about.

Macro Port 55, with a 50mm extension, is the same as Macro Port 105. This is a grade 1 addition; you can check with Nauticam's product management if you don't believe me.

Since Tamron is physically shorter, it will fit in the port dedicated to Sony for the same focal length. If you get a shorter port combination, you might get additional benefits such as more flexible combinations of wet lenses and better working distance when critical (SMC-1, for instance, especially with a multiplier). Have you asked this elsewhere?
