Olympus 7-14 mm f2.8 will not fit in Nauticam housings

I've been following this thread since it started and waiting to see how it plays out. The big decision I trying to make is whether to buy the 170mm or 180mm dome port for this lens. The 170mm is so much easier to travel with. It fits in my carry bags. I want one dome for both the 12-40mm and 7-14mm.

I get a feeling they are the same piece of glass - as measuring my 170mm its actually 180mm edge to edge (including the frame)

Unfortunately, besides some early preorder deliveries the new Oly lenses, both the 7-14 mm and 8 mm fisheye, seems impossible to get hold of. Both dealers in Germany and Norway i.e. list 1 -3 months delivery time!

I can assure you Richard that the Zen 170mm and the Nauticam 180mm are not the same glass.

The 8 mm fisheye is suddenly available again in limited quantities.

Still have to consider the Nauticam port solution which so far is not confirmed.

 

 

That's fine , but will the curve of the 4,33 minidome be good for the 8mm of Olympus , not leading to the issue of softcorner as we already undergo a little with the 8 mm Pana use with the 4,33 and 3,5 as well , ???

The 140 mm fisheye glas dome port might be preferable I have been told.

Zen Underwater has confirmed the recommendation for the Olympus 7-14mm:

Nauticam N85 to N120 60mm Port Adaptor, p/n 36204

Nauticam Extension Ring 20 with Lock, p/n 21120

Zen Underwater DP-170-N120

Due to the large diameter of the lens, it's designed so that the 60mm port adaptor is attached to the housing first, then the lens, then the DP-170-N120 with the 20mm extension. I've attached some photos of this setup.

hi jack ,

I do have the inon protector II dome port

Is it possible to use that one for the 7-14mm 2.8 with extension rings...??

Regards

We tried it in the Nauticam E-M1 housing and it will require that you add the camera body first into the housing, then the lens as with the 12-40mm. But it will need a much wider port body to fit the lens and a zoom gear. My guess is the the Nauticam N85 (MIL) to N120 (DSLR) 40mm ext adapter with zoom control, plus about a 50-60mm N120 extension and Nauticam 180mm N120 (DSLR) dome (or larger) should work fine. But Nauticam has not released a guide yet as they are still testing these new lenses.

 

We have a "first look" article on our blog here.

Has anyone had this setup in the water yet? Is there an existing zoom gear for this setup now or is a new gear required? I am getting a bad case of GAS.

Nauticam has new zoom gear (36054) and focus gear (36055) for the Oly 7-14 PRO lens.

The setup is pretty similar to other solutions allready available so no issues there I guess.

Please note that the Nauticam solution uses fewer parts; 36401 adapter and 18809 glass dome and that might be cheaper and certainly offer one less o-ring to worry about.

Sorry, I wouldn't have any information about the use of that setup. But you could set it up like the Nauticam and see how it works.

Here are an updated part list for the new Olympus lenses in Nauticam housings:

http://www.nauticam.com/product2.asp?id=390&sid=6

36054 O714-Z for Olympus M.ZUIKO DIGITAL ED 7-14mm f/2.8 PRO

36055 O714-F for Olympus M.Zuiko Digital ED 7-14mm f/2.8 PRO

36056 O8-F for Olympus M.Zuiko Digital ED 8mm 1:1.8 Fisheye PRO

Still no port solution for the fisheye provided...

I'm also following this thread in the hope of an almost do it all solution to the 7-14 & 14-40 zooms, regarding ports and extensions & things look good so far.

I have a question though: what's the likelihood of the 170 or the 180 mm domes mentioned in the previous posts being suitable for the new 8mm 1.8 fisheye?

John

Of course you can put a large dome for a fisheye but the Panasonic 8mm works fine with both 4.33" and 3.5" port (only 3:2 no vignette). The main use of a fisheye without Zoom is cfwa and wam and you don't want a large dome for those. I have the Panasonic 7-14 and corner sharpness is decent at f/8 with the nauticam 6" port. The 6" port is a cut of a 230mm dome

The ZEN Underwater solution for both the new Olympus 7-14 and 8mm lenses is now posted on the Wetpixel front page. Solutions for both Nauticam and Olympus housings.

They went for the previously speculated 30 mm extension on a dome port for the Pana 8 mm fisheye.

Undoubtly the Nauticam 4,33 mini dome with the 30 mm mini extension should also work.

Nauticam has updated their Oly 7-14 PRO solution:

Our testing shows that the lens works extremely well in our #18809 180mm Optically Coated Glass Dome Port. This is a DSLR mount port, and is attached to the smaller N85 mount featured on micro four thirds housings with our #36401 Nauticam N85 to N120 55mm Port Adaptor with Knob.

This does "work", but there is vignetting from the lens shades at the top and bottom of the 4:3 frame, so it won't be the recommended option.

The official recommendation for Olympus 8mm f/1.8 Pro will likely be 36048 140mm Glass Dome + a new 17mm extension, but these options are undergoing ongoing testing.

I had the chance today to try the 180mm Nauticam dome port with the N85 to N120 55mm adaptor (A137988).

The Inon protector II port (170mm) was vignetting at the corner, so i ended up in buying the Nauticam combo.

the good thing about the 7-14mm if you do 50 : 50 shots the picture is sharp above and underwater
