I see the Canon 8-15 with Metabones adapter is highly recommended with the Sony FF. Is this the way to go? Adapter is pricey. Thx

Not much getting around it, occasionally you'll find an adapter second hand, I found one at about half price. You could wait and see on the Laowa newly announced but there maybe issues. If you have any interest in using it (edit: it = Canon 8-15) with the Sony 2x for an extremely flexible 180°diagonal fisheye that zooms to a 28mm lens equivalent in horizontal coverage then you need the I think the latest version metabones as the Sony 2x nose will fit inside it. Requires a custom zoom gear printed which easy enough as designs are developed and available.

Hi, @Terri ,

As a Sony FF (a1) owner I can confirm the Canon 8-15 with either the Metabones IV or V or the Sigma MC-11 is a great option. I personally use the MC-11, but also own / use the Metabones V.

For a TC I use the Kenko 1.4x attached to the 8-15 followed by the MC-11 connected to the body. In Nauticam world, this works well with the zoom gear designed for the TC.

For most dives I prefer a water optic system such as the WACP-C (dry mount) or WWL-1B (wet mount) with the inexpensive Sony 28-60 lens. This gives up to a 130 degree FoV with a nice zoom range. The Canon 8-15 is what I use for those scenes that are a bit wider such as a massive wall, large view of a wreck, or inside a wreck when I do not mind a bit of the fisheye effect altering the vertical lines.

Hope this helps!

This is interesting...

You say the Sony 2x TC will fit into the Laowa 8-15mm f/2.8 fisheye lens? In case it fits mechanically and electronically it will be very interesting to see photois made with Sony 1.4x and 2x TCs...

No I'm talking about the Canon 8-15 with Metabones in reply to the original question about a Canon 8-15 with Metabones, with 2x nose fitting into the Metabones which requires the latest version if I recall correctly as earleir versions were smaller ID. I 'll edit the text to make this clearer.

Thx all. I do have the WWLb1 coming might stick with that for now with kit lens. Going to do tiger sharks southern Maldives end of the year. Just looked up the Sigma MC11. Are they okay? Any limitations? Cheaper.

Believe it only does S-AF, can't do C-AF, so not so good for video, unless you are shooting with certain Sigma lenses apparently.

use sigma MC11 + Kenko 1.4 on A7V and it works well for photo.

Not tried video...

Is this Metabones the correct one to use for a Canon 8-15 on my Sony? Metabones Canon EF Lens to Sony E Mount T Smart Adapter Mark 5 EF-E-BT5 I can buy one secondhand. Thx you amazing people

Yes. https://www.metabones.com/products/details/mb-ef-e-bt5

I think the Mark IV works also but im not 100%.

The Sony native Laowa 8-15 is also coming "in near future", if you have some time to wait (and believe it will be good).

Edited June 19Jun 19 by Sokrates

MkIV and V are identical electronics, the MkV is just built better. It's the version I have.

As I understand only the mKV works if you want to use it with the TC, the ID of the MkV adapter is bigger so the nose of the teleconverter fits through.

Hi all thx again for responses. I am now a proud owner if a second hand Canon 8-15 and a Metabones Mkv adapter. I know v little about using teleconverters. Are they needed? I have the 100 to 120 Nauticam adapter but now need to know what port to put this all under? I have a Zen glass port from my old Sony system and a Nauticam acrylic dome for Sony A7rv. Do I need a Canon 120 port. Looked at port chart not very clear. Any help I would be v grateful

Regarding TC, they are not needed. Its about your preference what kind reach you need for you lens.

A teleconverter is an optical magnifying attachment that sits between your camera body and your primary lens to extend its reach. It essentially increases the focal length of your lens, allowing you to get "closer" to distant subjects like wildlife or sports.

The most common versions are 1.4x and 2x. For example, attaching a 2x teleconverter to a 300mm lens turns it into a 600mm

For the Dome, i think you old dome will work just fine, all Zen domes (100/170/230) are listed on the port chart for the 8-15.

Extensions might be bit trial and error to find the perfect one. Theres info in this thread. Also few other threads also found on the forum.

I guess that 20 or 30 extension is enough without TC. But as the Canon 8-15 with Metabones is not officially supported by Nauticam, you have to rely on other users who have this for info.

So your setup would look something like this Housing->N100/N120 adapter->N120 extension->Dome OR Housing->N100 extension->N100/N120 adapter->Dome

Hi @Terri - congrats on your new Canon 8-15 and Metabones V. This will work perfectly with your Sony a7rV. I own an a1 in a Nauticam housing with this exact lens / adapter combo.

Which specific Zen dome do you have? It does make a difference. The Zen 100 is not the best choice for a high res FF body due to the ultra small dome size. There is also a version made specifically for the Tokina 10-17 which is different than the one made for the Canon 8-15, again neither are recommended for the high res systems.

The N100-N120 adapter with the zoom knob and Nauticam c815-z gear is how you will zoom the lens. Add an N120 30mm Extension for the 8-15 and Metabones for proper mounting. If you later add a 1.4x TC an additional N120 20mm is needed either as a 20mm added to the 30mm or using a separate 50mm Extension.

I use the Nauticam 140 dome port with my Canon 8-15. It is a full hemispherical dome which is what is best for the fisheye lenses and the smallest size that will provide good corners for high res FF systems. Teleconverters also work with this dome whereas they cause a horrible "smearing" in the corners when attempting to use it with the Zen 100 designed for the 8-15.

As others have said you need to know which DP100 port you have - it should be labelled, they have different amounts of extension built in, the one designed specifically for the Canon 8-15 is the DP-100-N120CR, this is used with no extension when added to the N100-N120 Nauticam adapter. this is the N120CR dome, you can see the built in extension: Assuming of course you are referring to a DP100 dome, we need to know which one to recommend the right extension.

Zen DP-100-N120CR 4 Inch Glass Dome Port for Canon 8-15...

Zen DP-100-N120CR 4in Glass Dome Port for Canon 8-15 /4L, Nauticam Housings, Removable Shade So you think you need a huge dome port to take advantage of your fisheye lens? Think again! Canon 8-15 /4L

If you have a different model Zen DP 100 you will need to work out the extension required.

If you have the 8.5" acrylic dome port it uses the 30mm extension on top of the N100-N120 adapter. it won't be as good for CFWA as the large dome pushes you further back from your subject.

Another option other members have been happy with is the Howshot 140mm, about half the price of Nauticam.
