WWL-1B on Seafrogs Housing

[newdiver 7]

Hi, I thought I had everything under control until I received my WWL-1B, it seems the bayonet quick release doesn't fit onto the M67 thread of Seafrogs housing port. The port has bigger outer diameter. What is the solution here?

Which port are you using?  I know others have reported using the WWl-1B on sea frogs ports.  I assume you are using this part on your flat port?:  https://www.nauticam.com/collections/water-contact-optics-accessories/products/m67-to-bayonet-converter-ii

I have tried on both 28-60 and 90mm macro, it seems the outer diameters on all these ports are the same. I am using the adapter in your link. I am fairly sure I read here that someone was using WWL-1B with Seafrogs housing but I can't find the post

[newdiver 7]

As you can tell from the photo, the adapter has a lot narrower gap and it needs to go around the port.

I think @Barmaglot uses WWL with Seafrogs housing, how do you manage to mount it?

[Phil Rudin 454]

You may have seen WWL-1 being used with the Seafrogs flat port because it ships with the 67mm threads so it can be direct mounted. The newer WWL-1B version ships with the bayonet mount not the 67mm threads and the bayonet mount converter II linked above is, as you would expect designed for the Nauticam 45 flat port. This is a one size does not fit all situation where you are attempting to adapt a lens to a port which it was not designed for. I am unaware of a workaround for this problem other than using the WWL-1.

Thanks Phil, that seems to be the case and I either have to swap the 1B for WWL-1 or try and see if I can find an adapter. Are the bayonet mounts different per the manufacturer? I have found this Fantasea one that looks like what I need but I am not sure if the Bayonet mount will fit the WWL-1B?

Very likely not, each manufacturer seems to have their own design. 

Any sort of adapter will move the WWL away from the port potentially introducing vignetting.  You can solve this by zooming in a little, but you lose angle of view.

You could try using a 67mm filter and remove the glass to make a short extension - just be aware, depending on material of construction  the ring may seize onto your port - might be a good idea to use some silicone grease on the threads - you would need to find one with female threads on the front to allow stacking - not all filters will have that.

Unfortunately, you do need to swap the WWL-1B for the WWL-1. The WWL-1 with the M67 mounting ring should screw onto the M67 threads of your Sea Frogs port. I can't imagine that the Fantasea bayonet would happen to be compatible with the WWL-1B bayonet. 

[newdiver 7]

Thanks, it seems not to be compatible. However there is this ring that might the solution?

If both threads are m67 it might well work at the cost of a little vignetting it is effectively what I described above. 

[newdiver 7]

Thanks Chris, I'm waiting for a shop to confirm if the converter will fit.

Let me know what you find. I think I am in the same boat - sony a7c with 28-60, sea frogs housing and a WWL-1B..

Most of it is sitting at my house and i have been traveling, but I am afraid I would run into the exact same issue

It is not my intent to discourage you Newdiver but I have all of those parts and it is not going to work in the way you expect. The ring you have attached from Reef Photo is designed for a specific purpose for Nauticam wet closeup lenses. I have attached some photos to help illustrate. The Nauticam SMC-1 and other Nauticam wet lenses like CMC-1 are designed with the threads moved forward on the lens while many other closeup lenses like the SAGA DIVE +5 C/U lens have the threads flush with the rear of the lens. The ring you have referenced (which ships with the SMC-1 and CMC-1) is used to make the rear of the C/U lens sit flush with the port glass when you are not using a Nauticam designed flip adapter. These are proprietary designs used to get the rear of the C/U lens as close to the lens as possible. Even a millimeter or two of additional space will reduce the magnification of the C/U lens. 

The same issue will occur with the WWL-1B if you try to mount it using a spacer. Further the bayonet mount adapter that attaches to the port has two small roll pins that align with the two indentations on the Nauticam designed ports, (see the ring photo detail) without these pins being locked in place the bayonet adapter will spin on the port and the lens hood will move out of alignment and vignette. 

For those thinking about buying the Seafrogs housings be aware that you will have the same issues trying to mount many flip adapters to the Seafrogs macro ports. The C/U lenses will need to be threaded onto the port and then removed for several different lens designs. 

If others are considering this less expensive housing you may also want to consider some of the less expensive wide angle wet lenses that mount with the 67mm thread.

If you want the have the Nauticam equipment mount the way it was intended to mount you can PM me I will be offering my like new Nauticam NA-A7C housing for sale this week.

Thanks Phil, I'll revisit the whole system once I get back home. I was so excited to have the new set-up for my travel to Fiji where I have just landed and writing this from the airport but it wasn't meant to be.

It was a last minute decision to travel to Fiji so I just managed to get the wwl-1b and no time to really look into it.

I don't - I've been looking to get a WWL-C to put on mine, but haven't had a good opportunity yet. I presume that is the lens side of the adapter in your photo - can you post the other side, i.e. the part that goes into the port?

[newdiver 7]

FYI anyone wanting to buy wwl-1B it will not work with Seafrogs housing. I got the ring adapter but as Phil pointed out it doesn't work, the vignette only goes away at 41mm. I have asked the shop to replace wwl-1b with wwl-1 that has the 67mm thread and that should hopefully work fine with Seafrogs housing.

@Barmaglot that is the port side, the other side is Bayonet mount.

Oh, I get it now - the threading is on the inside of that channel, with the Nauticam port having a thin protruding 'lip' that mates with it, and that white pin locks into a slot in that lip. Welp, there go my plans to get a WWL-C. I guess I'll give AOI and Weefine another look. AOI has their own quick-detach bayonet mount system, which, at least as far as I can tell by the manual, should be fine on a SeaFrogs port, and they also offer a float collar, but on the other hand, Weefine sells WFL01 replacement domes for just $57, so getting one scratched up is easy and relatively inexpensive to fix.

Hi Newdiver, did you get to test the WWL-1 on the Seafrogs 28-60mm port?

If you did how did it work? Was it ok?

Also would be interested to know if anyone has used a CMC-2 wet lens on the Seafrogs 28-60mm port? And if it work properly?

Hi, yes I have and it works fine. I don't have CMC so don't know about it.

Thanks for your reply, I recently found a second hand wwl-1 after my original message so was happy to find it fitted as well! Now just looking forward to diving this weekend to test it out!
