Cp 29 Posted January 25, 2010 The Nauticam website links to a PDF (look on the extension rings page) that demonstrates how the extension rings attach to dome ports. There is a locking mechanism in the extension to connect it to the port securely. The other observation/question I would have is that it looks to me that extension rings cannot be shared between macro and dome parts. There are two different types of extension rings available from Nauticam... here's the differences and uses: - Locking Extensions: These show up in the Nauticam nomenclature as, for example, "Extension Ring xx", where the xx indicates the length in millimeters. The locking port extensions work with all of the Nauticam domes, plus the dedicated Macro 60 port and Macro 105 port... plus they work with the port adapters, so you could use them with your Subal or Ikelite, etc port. They use a locking bayonet, the same bayonet that the housing port attachment uses. The extension bayonets have a small locking lever. Since these rings can be used with both macro and dome ports, I can see them getting used a lot. - Threaded Extensions: These show up in the Nauticam nomenclature as, for example "Compact Port Extension xx", where the xx again indicates length in millimeters. These extensions work in conjunction the Standard Port Base plus a Compact Port. This is a flexible and lightweight solution, but does not work with the dome ports nor the Macro 60 or Macro 105 ports. The compact port and extensions are threaded. The Standard Port Base is threaded on the outboard side, and has the bayonet on the inboard side as above. Using different sized extensions, you can cover a lot lenses, but since these only support the flat port, you won't get the wider lenses with this setup. The main advantage here is the lighter weight. The extension rings are less money than the locking version above, but I think when you factor in the cost of the two piece port it is pretty much a wash. Unless the weight is a primary consideration or you have a lot of different lenses that need a flat port, I'm leaning towards recommending the first approach. Hope that helps...

saudio 6 Posted January 26, 2010 Does anybody have the weight and dimensions of the housing handy? I'm upgrading from the XTi/Seatool and I'm curious how much weight and bulk this is going to add to my kit. The 7D by itself is quite a lump next to the XTi.

Steve Williams 0 Posted January 26, 2010 Thanks Lute and Chris for the info. I dug around and found the link showing how the Extension ring locks in. It's here ; http://www.nauticam.com/images/product/p_50.pdf So the extension ring locks to the port and then gets locked to the housing with the lever/ring. That's very cool. No more worrying about the big dome twisting off and flooding the camera. I think I followed you Chris, thanks! but I'm really a visual kind of guy and I was wondering when the Canon port chart would be coming out. I'm thinking that for a lot of us who already have existing posts we might only need to get the adaptors if we decide to go with the Nuaticam.

Dixter 0 Posted January 27, 2010 I had posted this question in a different thread.. the wrong thread... so here it is again... thanks Did'nt they have an assessory camera housing strap on the web site... I thought I saw it the other day, its gone now.. Just wanted to see what it looked like and how it works... I'm suprised more houseing manufacturers don't have these straps..

Cp 29 Posted January 27, 2010 (edited) Did'nt they have an assessory camera housing strap on the web site... I thought I saw it the other day, its gone now.. Just wanted to see what it looked like and how it works... I'm suprised more houseing manufacturers don't have these straps.. Is this what you mean?: Pretty simple and works well. On my subal I had something very similar (homemade yet still crude and unrefined :-). I'll probably replace one of the shackles with a bolt snap on mine so I can clip the housing to me when doing things that need two hands. For example shooting an smb.

Stewart L. Sy 12 Posted January 27, 2010 I think what Dixter means is the hand strap on the right grip of the Subals, it's not meant as a carry strap, more of something that holds the camera to you while shooting. You don't need a death grip on the housing say to shoot 1 handed. S. Share this post Link to post Share on other sites

Cheers, Steve Hi Steve, We have a working version here, but it's not quite ready for public consumption. The chart looks a lot like the Nikon chart, if that helps any, and the real one should be out very soon. I'll post/blog/facebook etc once I have it available. Both the Nikon and Canon charts will be a work in progress. We're trying to hit all of the major lenses immediately, and then picking up others as we go. Looking at the list on your sig, we have you covered. And I will say that we should be able to cover most every reasonable lens you might want to try, even if it does take a custom zoom/focus ring (which we can get made). Thanks, Chris Share this post Link to post Share on other sites
Mike L 0 Posted January 27, 2010 Its looking great Chris, keep up the good work! I cant wait to get these bad boys in my hands!! @Saudio, As for specs on the housing (correct me if Im wrong Chris) they are not yet released...but will be VERY soon. Share this post Link to post Share on other sites

Thanks, Chris Hey Chris, question about the ports: I'm interested in using a Sigma 17-70, and I understand it needs an extra wide flat port to allow for the zoom extension and still not vignette at the 17mm end. Do you know if such a port is in the works? Thanks. PS, I have a 7D housing on order. Share this post Link to post Share on other sites

Do you know if such a port is in the works? Thanks. PS, I have a 7D housing on order. As far as I know, Nauticam does not have a plan for a flat wide port, but, one nice thing is that with the range of port adapters we have, you can use one of the existing flat ports (i.e. S&S, Seatool) that might work. Right now none of the 17-70's are on our port charts... which one are you planning on using? What diopter are you planning to use? Are you set on using this in a flat port - would you consider a dome? Share this post Link to post Share on other sites

This one I was hoping to use this lens as a substitute for both my Canon 60mm Macro and my Canon 18-55, but I do own and want to use a Subsee 10X with the sigma, so a dome port is not going to work.

Jeannie 0 Posted January 28, 2010 Check out the new housing on the Nauticam USA website. Look close, there is a lot new here. You can also read about it in the latest UWP magazine. It should be noted that the images look computer generated. First deliveries set for Feb. Cheers, Steve Can anyone tell me that, if the Nauticam support INON port and 45 degree viewfinder or not??

I designed this hand strap for my Sea & sea housing to mimic the ones on the subals. The metal plate was laser cut out of stainless steel and bent to shape and the strap part was stitched up by a local wetsuit shop. I have also designed a similar hand strap for the bigger Gates housing handles. They really make quite a difference. Mark Share this post Link to post Share on other sites

RedSeaDiver 0 Posted January 29, 2010 (edited) Can anyone tell me that, if the Nauticam support INON port and 45 degree viewfinder or not?? I think Chris posted somewhere that the Inon 45 degree viewfinder can be used on Nauticam housings, but after reading the reports of everyone raving about the Nauticam 180 degree viewfinder I'm going to hold off until Nauticam release their own 45 degree viewfinder because it sounds like it will be significantly better than the Inon - I hope they get it out before I go to Bali at the beginning of May as I want to shoot macro and I need a 45 degree viewfinder for that.

Scuba_SI 39 Posted January 29, 2010 (edited) It will take Inon viewfinders with a 32mm barrel. on my one for nexus it has 2 locating pins, that might be an issue. I suspect that as the Nauticam viewfinder is compatible with Sea and Sea housings then any of the Inon viewfinders intended for Sea and Sea will fit the Nauticam.

Mike L 0 Posted January 29, 2010 Nauticam viewfinders are compatible with nearly all housings, however mounting rings are generally necessary for each housing. Currently there are mounting rings for Ikelite, Sea & Sea, Aquatica and Nexus housings. Share this post Link to post Share on other sites
