I reached out to UWTech and they responded that they have not tested their triggers with the Maxi at this time (and they were nice and prompt in the reply!)

Hi @Pavel Kolpakov , Will these work with the Retra Maxi with the same functionality of the other Retra strobes? I was going to email, but realized that multiple people probably have the same question. Thank you.

Phil can correct me, but if shooting Sony the 17mm Marelux to N100 Nauticam adapter (MX-31704) should allow all of the N100 ports to fit with the ~13mm shorter extension that Marelux uses. It will still take a little math to get it right across the port range as that is the equivalent of the 30mm extension on Nauticam, not just straight housing. If your Ports are N120, then there is a conversion ring for that as well, but it is 20mm so doesn't account for the 2-3 mm differences between the two housing brands - not sure that matters.

@Phil Rudin Any update on experiences with this optic? Thank you.

I use the Marelux Ninja V housing. It is just fine. My complaints are the Ninja is great but really for video only. If you can't touch the screen it is not great for stills as Canon (in stills) shows a bunch of the information under the screen parts that Ninja shows other information. You have to dig through the menu, as far as I can tell, to swap it between the HDMI clean out and the mirror, which is needed for hybrid shooting. So I would buy it again to record video and would get a different monitor/ housing if I was shooting stills. The housing is great, no issues (if not a big large... since the Ninja is a bit large). So video and want ProRes 422 or Raw? Awesome. Hybrid within one dive? Hmmm... Stills? I would look elsewhere (including Marelux's other monitor).

Also looks like it is available for Pre-order including the dive case. Unfortunately it looks like the dive case has the same mediocre button on top, even though they made the one on the camera better. This top button has been the one reason I have looked at other housings, but never been willing to pay 20x for a housing simply for a better 'shutter' button. Hopefully the new one still works better! It is unclear from the post referenced above whether the user was just using the camera without housing to 20m (and liked the buttons) or was using it in the housing. Eagerly awaiting more underwater imagery from this camera.

I went down the RAW rabbit hole with Canon for low light and can not get anywhere near the quality of video that the CLOG delivers. Often note mentioned, but if shooting challenging lighting, sometimes RAW is a real beast to make look good and beyond me in Post. Intrigued by Nikon NR being better. Or Sony. Also very intrigued by the C50 but on the fence whether the C400 or C80, with the triple ISO is really the advance compared the R5C, which is a great camera. Few housings for the C400 or C80 though.

While I have no experience with it, the recent release of a diversity of cameras that can shoot full frame open gate (3:2 form) has made me wonder how this would work underwater. It would seem that by extending the corners (aka shooting in 3:2 vs 16:9) it would really make corner sharpness much worse and we would have to shoot at smaller apertures and further push our lenses and cameras (and ISO). I'd love to hear people's experiences with this in real life, or thoughts.

The 15-30 has a MFD of 0.28 and works well behind a dome so it should be good on the 180 or 230mm. No idea on the 140mm. I'll bet its front element is too large to work well with the WWL-1B, that later of which is really designed for small front elements. This may be a nice lens for video (behind a dome and for certain shots), or stills if it works with an wet-mate or dry-mate adapter (WACP,WWL-1, Marelux Aquista) for a solution (with limited to 28mm and greater zoom...) I'm looking forward to seeing some real world examples underwater!

I've used one of these with triple clamps on both ends and then a ball in the center to mount. It works just fine. https://ulcs.com/product/db-cb10-double-ball-crossbar-arm/ I replaced it with a marelux cross bar which is more rigid and I like it more, but likely won't work with your hand strap. The CB10 was very flexible on how it was used. It does look like your red arm is threaded - so you could just mount a 1" ball in the center and put two (maybe longer) clamps on either side and you would be golden.

Ultralight has also recently released one https://ulcs.com/product/ultralight-ctk-dwtk-camera-dome-weight-trim-kit-for-underwater-camera-housings/ Not sure if it would be bad or not to have it in transport and not be able to set it down on the base. It is nice that it can move around based on which dome and extension is being used.

Since no one is jumping in... I have been looking into it for a while but have not (and may not) take the plunge. The best options I have seen are a bespoke option from Sexton - who adapts the lens to the front of a Gates housing. They now have it on their website: Sexton ProductsCanon 5.2 mm Dual-Fisheye VR Adaptor: Gates V-Raptor EditionBuilt for the Gates Deep Weapon Housing the Sexton Gates VR adaptor will allow professional filmmakers and hobbyists alike to take the Canon FR5.2mm F2.8L Dual Fisheye Lens and attach it to the 8K REDI've worked with the company before and they are excellent, however I don't have a Red Weapon and so the investment to try it is a lot. Part of me is also concerned about having to crawl out of the Canon ecosystem to Red to use a VR designed by Canon. I just think the post processing may be painful. I think one of the issues is the size of the lens - the 5.2 is 121mm across so won't fit in Nauticam N120 or Marelux. I'm also concerned about dome size even thought they are wee and fisheye. Gates also just "released" a housing for the new BlackMagic Apple Vision VR Rig. Gates Underwater ProductsGates Immersive Housing - any Camera, any Lens - Gates Un...Gates Immersive Housing is a dedicated underwater imaging system designed expressly for the Blackmagic URSA Cine Immersive camera from Blackmagic Design. An integrated platform, Gates Immersive Housin Note price for hire (upon request) and they only rent them. Plus just the camera is 30k USD. I'd love to hear if anyone has found other solutions that may work for this.

Kinda hard to find comparable images and both lenses are so good that it is splitting hairs. These are all the 8-15. The cage gives a pretty good indication of corner sharpness (we do experiments to understand the role of human activities in the ocean and the cages are how we understand the role of fishing). Also 8-15. I find the corners are not ALWAYS amazing on the 8-15... but I think I often have the corners out of the DoF and blame the lens rather than focus and user.

Hi Dave, Do you mean color grade or white balance? Only way to white balance is shoot raw and then there is not a great option for cost effective programs. Davinchi Resolve (the free version) is the one that I have always been pointed to for color grading for those that don't have access to Premier (Which is stupid expensive and a subscription...hate the model). I shot raw video a few times and ran away. Not worth the WB in post. Best.

I put some examples on page 2 of this thread: (not sure why the hyperlink box is so wonky.) 7-14 - Nice and sharp, easy to use. Great lens. I can pull some 8-15mm photos for ya if you want. Slightly less sharp (my copy) but not really notable unless corner peaking.
