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

[EspenB 15]

The comming Olympus 7-14 mm f2.8 lens will not fit in an Nauticam housing due the lens diameter (approx 80 mm) is wider the maximum inner diameter (approx 73 mm) of the Nauticam port system.

 

This was a real bummer as I was looking foward to getting a f2.8 wide angle lens.

 

Lets hope the upcomming Olympus fisheye 8.0 mm f1.8 is a better match. At least it looks slimmer in the pictures.

EpsenB, I think you are over reacting at bit regarding the issue of the new Olympus 7-14mm F/2.8 zoom. Nauticam has a 85mm to 120mm extension with a zoom control allowing you to use the 180mm optical glass dome port (120mm on the housing side) with the current mirrorless Mini housing line. After the adapter is mounted the lens is installed from the front of the housing and then an additional port extension and the port are installed over the lens. This works well for lenses like the Olympus 12-40 zoom and the Zeiss 12mm on Sony NEX and A-APS-C series housings. The zoom gear would be operated from the extension and not the housing zoom dial. I am sure that ZEN Underwater will also have a port solution for this lens going forward. The issue will be to determine the amount of extension needed for this lens. Olympus 12-40 and Panasonic 12-35mm use 20mm of extra extension, Panasonic 7-14mm no extension, I would expect Olympus 7-14mm be be in the 20 to 25mm range if this system does in fact work. The 85 to 120 extension would actually work with any of the ports with the 120mm port mount so you could in theory go to a 230mm port if you wanted with the correct amount of extension. The extension part number is 36052 on the Nauticam port chart.

Great feedback Phil! Looking forward to using this new Olympus glass underwater.

Yes, Phil I see now that this possibility exists for the Pro 12-40 mm lens, to facilitate using an expensive and fragile glass dome...

 

The extension is probaly around 20 mm as you say, so you need NA-36052 + NA-21120 + NA-18809 + focus/zoom gears which probably adds up an really expensive amount.

 

Also, the mounting method is a real pain in the ass with several elements to add in the correct order.

I have the 180mm glass dome and extensions for my E-M5 Nauticam Housing and use with the 12-40 f2.8 lens

 

Works great, took a little getting used I the size, and attaching the lens to camera body inside the housing & THEN securing the port with extensions attached.

 

Considering the only other ports I had used were the flat port for 12-50 kit lens and the 4" mini-dome for the fisheye I will admit to being nervous about the slight movement of the multiple parts.

 

System has worked flawlessly since I got it

 

Love the lens, and the ability to get wide-angle images even with the low viz waters around Vancouver, British Columbia.

 

Zoom for the 12-40 is controlled by the knob on the housing. Had hoped that the focus knob on the adaptor port would be able to achieve manual focus, but have not figured a way to have both zoom and focus gears.

 

Will definately be having a close look at the Oly 7-14mm when released. The wider angle would be nice.

 

Regards

Thanks for providing end user report on the N85 to N120 adaptor. I guess the dome extends well below the housing? Do you have a picture of your set up?

 

I must say I was hoping for a cheaper option since I have the Pana 7-14 in the acrylic dome allready.

 

This new dome and adaptors will probably set me back at least 1500 euro and probably the same for the lens, making it an 3000+ euro upgrade. Yiikes! ;-)

[adamtaylor 27]

EspenB the dome port hangs approximately 3.5cm below the bottom of the housing. Definately taking some time to get used to the size of it compared to the flat port or mini-dome for the fisheye... For close focus wide-angle it definately changes some angles that you can achieve when a foreground subject is close to the bottom / rocky reef.

 

Here are some images of the my housing with the 12-40 f2.8 lens attached & port off, then a couple angles with it on.

 

I am hoping the upcoming Oly 7-14 will work with the same set up, or maybe with one less extension ring?

 

Regards,

I have been hoping the new Oly 7-14 will fit in the Zen 170 I use now for the Panasonic 7-14 and Oly 12-40. I have my doubts that it will fit... http://www.43rumors.com/the-big-olympus-pro-lens-size-comparison/

 

But am keeping my fingers crossed, as I don't really have room to pack another largish dome. I guess the other option is to go to the Nauticam 180 with the adapters for both the 12-40 and 7-14, but I wold prefer not to. We shall see....

[BengalBoy 2]

Does anyone here use the Nauticam 7" Dome with the M.Zuiko 12-40 Pro?? Its seems that it would be a easier (no extensions to attach) and cheaper solution than the Zen domes. Also, wouldn't it work with the upcoming 7-14mm Pro?

Naticam Port chart: http://www.nauticam.com/images/catalog/catalog_18.pdf

 

The 12-40 mm PRO fits in either the "36129" 7 inch dome or the "18809" 180 mm glass dome.

 

The 7-14 mm PRO is too wide for the N85 port system (as illustrated in my first post), thus you will need the N85 to N120 port converter as previously depicted in this thread. The lens neds to be installed from the port side after the camera is installed, then you need to install the dome port.

From the size comparision pictures it looks like the extension needed might be longer than the 20 mm you use today.

[EspenB 15]

BH Photo seems to confirm a june release for the Oly 7-14 f2.8. There is still no official info om actual size of the lens...

[EspenB 15]

Finally there seems to be an official Olympus announcement of both the 7-14 f2.8 and 8 mm fisheye f1.8 early next week.

So was the answer, yes you can use this lens with the Zen 170 mm dome???

That last post was mine.

[EspenB 15]

Final spec for the new Olympus lenses:

 

 

 

• M.ZUIKO DIGITAL ED 7-14mm F2.8 PRO
  – Will be released in Japan in late June 2015
  – Dust-proof drop-proof (11 places sealing)
  – Total length: 105.8mm
  – Maximum diameter: 78.9mm
  – Weight: 534g
• M.ZUIKO DIGITAL ED 8mm F1.8 Fisheye PRO
  – Maximum magnification 0.2 times
  – Total length: 80mm
  – Maximum diameter: 62mm
  – Weight: 315g

 

As previously speculated the diameter of new Olympus 7-14 f2.8 lens is to large to fit inside the Nauticam N85 port system.

[EspenB 15]

If we assume that the integrated hood is maximized for both lenses, the lenght difference is 105,8 mm - 83,1 mm = 22,7 mm. So it seems that the 20 mm extension previously shown in Adam Taylors picture above should be sufficient. A 22,7 mm extension is probably unlikely?!

The extension part number is 36052 on the Nauticam port chart.

 

I got the 36052 port adapter yesterday and unfortunately its useless for the descriped purpose as there is no external lock solution on the Nauticam 36052 adapter. This makes it impossible to secure the adapter, then the lens and lastly the dome port. With the 36052 you must assemble the port adaptor to the dome port before attaching it to the housing. Thus it becomes impossible to fit the Olympus lens inside the adaptor port assembly.

 

Likely there will be a new port adaptor for M4/3 with an external lock like the one for The Sony E-mount system, like the Nauticam 36204, but the Nauticam 36052 can not be used.

 

Picture shows the 36204 port adapter (60 mm extension for sony e mount) with external locking solution, a feature missing from the 36052 port adapter.

[RogerC 4]

As long as the lens fits through the hole in the housing, I'm optimistic that nauticam will find a solution.

 

I am looking forward to it, I really prefer a rectilinear wide angle lens, the zoom out to 14/28 is nice for shy subjects, and 2.8 sure is nice.

 

the f1.8 8mm fisheye probably makes more sense, though. Easier to swim with and will probably have sharper corners, too.

Undoubtely they will make the necessary adaptor lenght with lock, but the current solutions can not be used.

[Phil Rudin 455]

First let me say that both the Olympus 7-14 F/2.8 and the Olympus 8mm F/1.8 fisheye are even more impressive in the flesh than in the photos on the interweb. I used the 8mm last week and it is excellent with. Both lenses are being tested and the main issue is getting the correct port extension for the very best possable corner sharpness for the port size. I am sure both Nauticam and ZEN will have solutions for these lenses around the time that they are released.

The build quality and image quality of both lenses exceeds what we have seen from M43 wide lenses so far.

Just noticed that Nauticam USA have an update on their Facebook page stating "Testing the new 7-14mm f2.8 PRO in the pool" so we will probably know more very soon.

[adamtaylor 27]

Has anyone heen able to physically fit-test the new 7-14mm in a Nauticam?

 

A quick measure of my adapter port this morning showed a 78mm inside diameter. This was with a tape measure, not a protractor so may not be completely accurate. I am hopful that the adapter / port assembly will fit over the new 7-14mm

 

For those unfamiliar with the 180mm port, extension ring and adapter they have internal locking mechanisms to lock the components together. Basically you put your camera in the housing, attach the lens from the outside, THEN slide the completed port assembly & adapter over the lens. The completed port assembly is locked in place using the mechanism on the side of housing.

 

The million dollar question appears to be is the internal diameter of the M4/3 to SLR adapter ring wide enough to fit over the new Oly 7-14?

The Oly 7-14 is listed at Maximum diameter: 78.9mm . The internal diameter of the 36052 port adapter is only 76 mm.

Thanks for the teaser.

 

You probably need 70 mm extention for the 7-14 mm (47+22,7) so the best guess is that you tried it with the 36204 60 mm extension with the external locking function.

 

For the fisheye, the previous 4,33" minidome might be good with an additional 30 mm extension...
