Retra team today tested MAXI strobe with UWTechnics TTL-Converters in TTL, HSS and M modes. Everything worked nice. So, MAXI strobe is fully compatible with UWTechnics TTL-Converters., this is confirmed now.

Thanks @ChipBPhoto and @bghazzal. That is how I have mine setup, finder/monitor manual with C3 to swap. In monitor the camera goes to sleep just fine, but not when the viewfinder is active. I assume it’s due to the eye sensor but I’m not sure. I’ll try again out of the housing and see if that works.

Hey @akarnani , On my a1 I set the view finder selection to be manual. I then set button C3 to switch between the VF and back panel. This allows me to easily switch as needed and defeats the issue of the auto sensor picking up the housing as your eye. This is the same as what @bghazzal shared. It works great! Cheers Chip

Have you tried turning off the eye sensor? I read that it doesn't work in the housing anyway You can map a button to switch between the two instead: https://www.nauticam.com/blogs/news/the-sony-underwater-setup-guide-for-a7rv-a7iv-a7siii-and-a1 EVF/LCD Selection Underwater I also want to manually decide between using the EVF or the LCD (this is necessary as the eye sensor doesn't work underwater). To switch between the two underwater we need to disable the automatic switching and assign a custom key to toggle between the two. To do this, we need to navigate to: 'SETUP' > 'Finder/Monitor' and set this to 'Monitor (manual)'. NOTE: We choose 'Monitor' for now, otherwise you'll have to do the rest of this step while looking through the EVF. Next, we'll assign the toggle control to the 'C3' Button which is easily accessible with your left hand on the rear of the housing. Navigate to: 'SETUP' > 'Operation Customize' > 'IMAGE Custom Key Settings' > and assign 'C3' to 'Finder/Monitor'. In the 'Finder/Monitor' menu you can also set the brightness, color, quality and frame rate of the EVF. I prefer to maximize quality and frame rate and generally leave the color and brightness as is.

I use the neoprene bag that came with the MFO3 to protect mine during shore entries. Cinch down the cord on the cloure to keep it on. Take it off in the water and clip it off and reapply during the safety stop. Just don't let go of it as it will float away. An alternative might be a beer cooler used to keep bottled beer cold while drinking, probably widely available. You might find one around the right size. The advantage for me is it keeps the lens wet till I can soak it in fresh water after the dive. You could probably do something similar for your macro port.

I’m on my first trip with my A1 in a nauticam housing. Above water the camera sleeps normally after 10s of inactivity. But in the housing, the camera won’t sleep. I think it’s the eye sensor picking up the housing? If I set the camera to manual screen then the camera will sleep so, but I’d much rather use the view finder. Is there some setting I’m missing, or a trick y’all have figured out to fix this? Otherwise I’ll resign myself to using the power switch all the time.

Cephalopods shot during my recent trip to Anilao, April '26. feedback welcomed.

Hmmmm, maybe the OP needs a Dave Hicks cover for his rare S&S lens! Maybe I do too for my Nauticam dome ;).

I was NOT able to get Advance mode to function well, lots of ficus breathing even with good contrast and light. Green mode worked better but seemed to be slow to close the aperture and fire the shot. Updated the adapter firmware and HUGE difference. Advanced mode now works far better, maybe a bit better in Green mode. I'll be looking to 3D print a zoom gear since I can now use DMF with Advanced mode.

Yes, i made a TPU rubber design that is much easier to install underwater than neoprene and it rinses and cleans better. Currently available Dome Ports are:• AOI DLP 06• Nauticam 8.5 inch • Nauticam 140mm• Nauticam 180mm• Sea & Sea 12mm • Zen DP 100• Zen DP 170 https://makerworld.com/models/2391039

Hey man, thanks for sharing these images. Those flares look pretty nasty. I am seriously considering the WACP-C as an all-round lens, but after seeing this, I might go with the traditional dome port and 16–35mm setup instead. Does this happen every time you shoot toward the sun? I actually enjoy shooting into the sun when using strobes because it creates great sunballs, so I'm wondering how much of an issue this is in practice. Hey man, thanks for sharing these images.

I took my TG 6 with the FCON 2 Lens on when I went snorkeling. I told the camera I was using the FCON Lens II. When the camera got below water the camera would zoom in to cover the full frame. When I tried to go to the full 180 circle mode it would not ?

I have a significant divot in my Sea&Sea 12mm from a shore exit because I couldn't get the neoprene "bikini" cover on. I've been trying to figure out a better design since. I believe Dave Hicks has 3D printed designs in TPU.

I always keep my lenses covered entering and exiting. My WWL hard cover is drilled for a piece of cave line and bolt snap. The cover is always attached to the lens safety line or clipped off to my scooter ring when in use. My CMC lenses and dome port have neoprene covers which likewise have a small bolt snap for me to clip them off to the camera when on the lens or to my scooter ring in use. Ikelite has several full neoprene covers with a zip drawstring that are easier to slip on than the bikini type. I use one of those on my 4.33 inch Nauticam dome. And, of course, a bolt snap.

While on safety stops in the past I've thought about how "best" to protect all the glass surfaces while entering/ exiting the water. The perfectly fitting branded covers and cases for multiple wet diopters are SUPER expensive, and in my past experience, most often they fall out of fingers to the bottom of the ocean. One thought was custom covers made out of neoprene with bungie/elastic to hold in place. I'd like to get covers made for: - currently unprotected Nauticam 87macro port with dual flip - MFO-3 on one arm of a dual flip - both front and back of lens - SMC-1 on other arm of the dual flip - again both front and back of lens - EMWL (thinking "sock-like") I'm fortunate that a friend and fellow diver gifted me a custom made neoprene cover for my WA 13mmRS lens - but I personally don't have "a guy in Thailand" to make any other covers. Anyone have any suggested solutions (premade?) or recommendations on what to tell a local tailor or where to find salt water proof supplies other than recycled wetsuits?

Thanks for this @Davide DB !

Hey Romik, thanks for the great feedback and great video! I actually have an extra camera that I can use for a top-down shot, so maybe the WACP-C would be the best option after all? :)

We have probably the best article in this topic:

Tim, I have the Turtle 3 for my Nikon D500 in Subal housing and do not remove the LEDs from the trigger. I just remove the trigger from the hot shoe whenever I need to remove the camera from the housing. The HSS works with my Retra Prime+ and the Turtle.

Hmmm, that's an interesting thought. I guess though that you can leave the electronics box attached to the LEDs and just slide the box off the camera before removing it from the housing? In the same way you would remove a hot shoe connector?

Hi all! Have a trip scheduled next month to Malapascua to see some Threshers Ill only be having a GoPro with a Backscatter Sharp Wide Lens Pro No strobes or lights allowed in these dives Anyone have any tips on settings that can be useful in this situation? I know that I’m not expecting any cinematic footage with this setup, but I’d like to maximize it as much as i can Thanks!

There is no flare problem when shooting sun with WACP-C. You will get flare with mispositioned strobes facing the WACP glass but not otherwise. For snorkel with whales its a non issue (no strobes) Having said that I wouldn't bring WACP-C for whale snorkel trip. Never been on one but if it is anything similar to my Orca experience in Norway you are going to spend a lot of time on the small boat chasing the whales and jumping in and out of water. And so you may miss a lot of pictures and videos topside. With dome not so. All my topside shots in Orca video are with camera inside of housing behind 180mm glass dome. Also one of attached pictures. For Orcas I had 20-70 F4 with 180mm and 16-35 F4PZ which I haven't used. For whales I probably would. Honestly I think that all technical discussions for snorkel trip are nonsense. The rule of the game is be light be quick and have great AF. Also external monitor will be invaluable for these shots floating on the surface extending arms down and getting shot from down below. Wed5Pro may prove to be the best investment :-). Good luck :-) WACP-C 20-70 with glass dome

Well, a bit late, but for a period I didn't use the forum a lot. Here the answer for future readers I just attached to the tray (with a screw and nuts) a quick release arca swiss, that I can use to attach the tripod I'll attach 2 pictures of it so it will be clearer. I don't have the tray anymore, but that's not the important part 😁

I am a bit late to the party, but here my pimped GoPro, for macro, super macro and wide 😁 Lenses: Inon G55 (super macro) Inon G165 (macro) Inon G140 (wide) Tray, main floater, clips and the 2 short arm from AliExpress (really cheap, but served me well for 3 years) 2 Arm floater with lens holders from inon Tripod from Joby (5k version) Torch DL08 from wurkkos Torch here On my Instagram you can see some of the results (I have that problem, the one that I like to shoot a lot of cool video, but edit just a small part of them 🫣) Insta: Elvandar
