How much smaller is the dealbreaker for you? Below are the A7RV housing sizes with base housing only. Ports ect should be fairly same size for all. Isotta Nauticam Marelux Sea&Sea Width 28.2cm 34cm 33.46cm 33cm Height 18.6cm 17cm 18.98cm 16.9cm Depth 12.7cm 12.7cm 13.23cm 13.7cm Total 59.5cm 63.7cm 65.67cm 63.6cm % larger 0 7.06% 10.37% 6.89% Weight Not listed 2.7kg 3kg 2.9kg Isotta is clearly smallest in width, and you can see that in pictures also. It also looks most crammed with buttons in the back. Wouldn't say Isotta is very compact compared to other aluminum housings, with 7% difference.

Hello, I've owned an Isotta housing for my Nikon Z8 since last year and I'm very happy with it. Before that, I had a Hugyfoot housing. What I appreciate most is the ergonomics; all the controls are perfectly positioned (I have small hands and I was sometimes uncomfortable with my old housing). It remains compact despite the size of the Z8, with double seals, a vacuum system, and a locking mechanism and the price... It's compatible with Nauticam, so I use the 24-50mm lens with the WWL-C. Elisa from Isotta is very responsive and answers any questions quickly. However, it's important to clearly define what type of flash connection you'll be using. Personally, I didn't get the Isotta trigger to mount a TRT Electronics Smart 3. Upon delivery, the housing was assembled with LEDs and cabling incompatible with the TRT. I had to order compatible parts and replace them. Isotta offered to make the modification at the factory to keep the warranty, but this would have meant returning the housing I had just received.

Hi Dave, Nice Cap/Cover! I created a similar solution for my WWL-1, simply closing it off at the front. However, it's also secured using bungees. I created a similar solution for my WWL-1, simply closing the front. I also use bungee cords for securing it. In my opinion, the protection is just as good with the mesh at the front, and the advantage is faster drying. I printed my cover with PETG. (If anyone wants one of these parts for the old WWL-1 (without a buoyancy ring) just let me know and I'll upload it to Makerworld.) I also have TPU for AMS from BambuLab, but I'm not entirely happy with the material yet. It's quite hard and therefore tends to break more easily. I used TPU for AMS for my snoot adapter, but I'll probably reprint that part with regular TPU soon. Tino WWL-1 Cover/Cap, latest version, printed for a friend.

I had an Isotta Olympus OM-D EM 1ii housing and loved it. I replaced it with an Isotta Sony A7RV and also love it. I have also had an Isotta GoPro and TG housing. I was near southern Lake Garda by chance in late 2024 so visited their factory. Lovely family-owned artisan manufacturing company which, for me, adds to my enjoyment using their products. The quality is great. The housings are compact and they have a unique door system with double o rings. Also, double o rings on the ports and I think also on the buttons and knobs. The ergonomics on the models I have had are great (I use back button focus). They are more simple inside than some other housings which I think is an advantage. They have port adapters giving options for the Nauticam dry lenses if you want to use them. (But my favourite lens is the adapted Canon 8-15 with teleconverter or on it's own.) Since a couple of years ago they do have ports with the correct front 67mm threads for use with the Nauticam bayonet fitting (e.g. WWL-1B). The only negative I know off is that since they are quite a small company they tend to be slower than Nauticam or Ikelite to bring out new housings for the latest models, or less common cameras.

Thanks I saw mention of S1 and S2 but no explanation of what they are. I am just thinking, exploring options none of which seem attractive to me. I am sitting on a pile of money earmarked for strobes but not a strobe exists that I am satisfied with. I am of the mind I will not pay for a strobe that has RC/Sony only modes and no slave TTL. Like WTH! Or they are big enough and heavy enough to serve as a boat anchor and put my airline weight limits to the test! I am a manual shooter but slave TTL is useful at times and I have spending $2000 plus on strobes without that capability and modes I have no use for. My rant for the evening. If Retra could shrink the Maxi (?) to a Midi and say it ran about $1,000 per unit I could get excited. If it had slave TTL.

Only the 100mm objective lens left - as new condition, not a mark anywhere. New Price is US$1,700 plus tax. My price $US1,200 - 30% off. Includes all postage and PayPal fees. Thanks to member DocToc for purchasing the rest of the package, excellent communication, payment. Pleasure to deal with, would recommend.

DS51 is Sold. DS125s are still available.

I have an old Isotta housing for my canon G5x... and since 4 year an Isotta with my Canon R5. I'm happy with it... it is a brand from Europe and in the actual situation It is important for me to buy "local".

I am using Bambulab TPU for AMS - So yes it does work with the AMS! I've only recently started to work with this version of TPU, and it is very nice. It is too rigid for softer rubber parts needed for things like my sync-cable-connectors, but great for more structural parts. This Port Cap and the Stage Bottle Hose Organizer work great with it. It's also super convenient to have it loaded and ready in the AMS at any time. https://makerworld.com/en/models/2025358-scuba-hose-organizer-for-stage-bottles#profileId-2183580

Another option is the port 65 and 12-50ez, has to be at 14mm or so but a very good combo.

The grip tabs on the cap are not going to catch due to the bevel at the bottom, but the bungees will hold it in place. I'll add this to the model.

I am curious about the 68 shore TPU - who makes it, and is it AMS compatible (I'm guessing that it is not)?

$500usd includes two batteries, charger and Olympus flash. Looks mint. Just not using it and perhaps someone knows an aspiring photographer who can.

Fantastic! Although I mostly scuba I also enjoy breath hold photography in kelp forests.

Precisely

One data point doesn't make a trend but it is a start. Hopefully there will be more positive ones to follow and maybe this will spread too.

I think yes, it is S1 mode, single flash Bill

A quick question that perusing the OM did not satisfy. There is no mention of a pre-flash cancel, does this strobe have that capability? I understand this is a full manual only strobe, nonetheless I need a pre-flash cancel mode.

Join me on an underwater adventure as I dive into the warm, crystal-clear waters of the Philippines. This video takes you below the surface to explore vibrant coral reefs, some of the best macro diving in the world, featuring some of the incredible marine life that makes this region one of the world’s top dive destinations. From swirling schools of reef fish and graceful sea turtles to tiny macro life hiding among the corals, every dive reveals a colorful, thriving underwater world shaped by tropical currents and nutrient-rich seas. The Philippines sits at the heart of the Coral Triangle, home to some of the greatest marine biodiversity on Earth, and every descent feels like entering a living aquarium. This journey highlights not only the beauty of these reefs, but also the fragile balance that sustains life beneath the waves. Whether you’re a diver, ocean lover, or simply curious about what lies below, this video offers a peaceful glimpse into an ecosystem bursting with life and color. Filmed in: The Philippines (Anilao and Puerto Galera) Looking forward to hearing your thoughts and critiques! Thank you for watching!

Same here, lack of a slave TTL mode is pretty much a no go for me also. I would buy the HF-1 or the new Atom but for one thing, no slave TTL. My Sony and my Canon neither support RC or the Sony (RC) modes and will work only in a manual mode with those strobes. And whatever triggers Backscatter offers do not work with either camera system. Not everyone shoots Olympus or a TJunk, seems to be a blaring omission to me. The DS130 might be a go but YS strobes seem to have issues with reliability.

I sent you an pm.

Hello, I'm thinking of changing my current underwater rig for something smaller and I've heard Isotta housings are very compact compared to other aluminium housings. Is anyone here using an Isotta housing and loving it? I'd love to hear thoughts/feedback. I use my setup professionally and my camera of choice for the Isotta is a Sony A7RV. Many thanks, Lou

If you haven't bought the port yet, I’d recommend looking for a used 14-42mm II. I found mine for 60 euros. There’s also the 14-42mm PZ, which uses a shorter port, but based on tests, the 14-42mm OIS II seems to be the better lens. P.S. We are speaking of plastic kit lenses...

Hi Lou, Welcome aboard! We have other freediving photographers here in the forum. We hope you enjoy your new community. Ciao

Hey hello! I'm a freediving ocean storyteller with a background in marine biology based in Pembrokeshire, Wales, UK. My main photography focus is on marine life but I also enjoy creating natural artistic shots of freedivers and swimmers, with a leaning towards the natural nude! Living in Wales I spend a large chunk of the year waiting for the viz to improve. My husband and I spent three years as liveaboard sailors between 2020 and 2023, exploring the Canary Islands and the eastern Caribbean, maximising freediving and photography time. My favourite place to dive is still the kelp forest on a sunny day, with just my breath and natural light as illumination. I love the challenge and drama of it. I'm a certified scuba diver too, and I spent many years as a scientific diver, monitoring marine life in a conservation role. I recently found the WaterPixels community and am here to share my knowledge of marine life and photography, and learn from other members 🤗
