Really beautiful documentary, and a fascinating environment that I’d only ever heard about before. There are even some CFWA shots, like the gastropod at 12:40. Thanks for sharing!

Welcome on board, good to see another OM-1 user on here. I'm also using Nauticam, but you could also consider Isotta and Marelux has recently released a housing, though details are thin on the ground, seems like it has a smaller port system and only lists a 140mm dome. I'm shooting with either the 60mm macro plus MFO3 (a great accessory as the 60mm macro is a bit long) and for wide angle the Canon 8-15 adapted with metabones and the Nauticam 140mm dome. If you were interested in this option the Isotta setup will be significantly cheaper. Previously I used the the Olympus 12-40 and still do occasionally when temperate water diving around home and also had the Panasonic fisheye with the tiny Zen 100mm dome. The big advantage of the Aluminium housing is they have an optical viewfinder and importantly for macro you can use a 45°viewfinder in them. The AOI housing only uses a window where you can partially see the viewfinder and you rely on the rear screen.

No, I expect not approval was manual and the site seems totally unattended and can only be viewed by logged in members.

Actually the 16-35 GMII is on the WACP-1/1B port chart, but it only works between 28 and 35mm zoom settings and will give you about the equivalent of a 12-16mm zoom in rectilinear terms based upon the horizontal field of view. This is not a wide zoom range and you could be left wanting more reach if the sharks are at all shy. If you want to have a zoom behind the WACP, maybe look at the Tamron 28-75 which is on the port charts if you want to be using a lens with better quality than the Sony 28-60. That lens is usable from 28-45 and will get you out to about equivalent to a 30mm lens. I expect it bumps into the back of the WACP beyond about 45mm. I seem to recall some discussion on this lens on the forums. Port Chart: https://drive.google.com/file/d/1oPHvkUhf-_rRNqZWTnuIHVa_xnXhSkvI/view

I was in Socorro in Jan and here's how I did back rolls with a camera. Fold the strobe arms in and tether it to a D-ring on my shoulder strap (just in case). Pull the camera into my chest with left arm and wrap that arm around it. Further hug the camera with right elbow and bicep. Right hand on mask & reg. Worked fine for me and I think I'll continue to use this method for all back rolls instead of having the camera handed down.

I tried to learn DarkTable and it continuously kicked my butt. Kudos to those who have mastered it.

Is it still impossible to get a new account approved?

Thanks Tim! I'd like to hear your thoughts on choosing Nauticam over AOI and what lenses you've been enjoying shooting underwater. The only lens I have right now that is appropriate for underwater is the 60 mm macro.

I'm wondering if anyone has any updates on the info in this thread. I'm interested in cheap lights for a downline (bonfire / blackwater diving), but I keep stumbling on battery life and longevity, which are major weak points of these cheap lights. If you factor in buying good 3×21700 cells for each light, it does add up. The other issue is that they don't have constant output, so hanging them on a line would mean a constant drop in illumination over the 2 hours or so they're on. Realistically, for a pair of lights, I need 4,000 to 6,000 lumens per light, offering a decent illumination for 2 hours. I've looked into Leton Power lights (the "12,000-lumen" and "8,000-lumen" models), but they're still expensive for what they are. Rechargeable LED fishing lights are better value (but have no beam), although the ergonomics aren't great (no underwater switch, just a remote that has to be left on the surface).

Unfortunately, you are trying to match 2 items that are not designed to work together. Please consult the Nauticam port chart found on Nauticam.com or Reefphoto.com to see the lens options and extensions for each.

Today Marelux added a Marelux five inch to Nauticam N120 20mm port adapter so Marelux extensions, ports and the Aquista 135D wet lens can be used on Nauticam housings. This adapter can be found in the products section under ports and adapters at the Marelux.co website. Marelux has also added Hugyfot, Isotta and Subal to Marelux adapters. Additional Nauticam adapters have been added as well NA N100 20mm to MX, NA N120 30mm to MX and NA N100 17mm to MX for use with WACP-C among other things. Marelux already has an NA N120 20mm to MX for use with ports, extensions and N120 WACP-1 WACP-2 and FCP if you already own them. Marelux already has a Sea & Sea to MX 20mm. I believe Marelux will be adding to the dry mount line of wet wide lenses this year. For praticual buyers these additions make the transition to Marelux products more manageable.

Hi Phil - to be clear is is an adapter that allows a Marelux port (or Aquista 135d) to be mounted to an N120 Nauticam housing? I know they have had the other way for a long time. Thanks!

Looks like boys got the episode up.

gnarliest_gnome! Love the username. Welcome! (Just got my (Nauticam) OM-1 housing)

Welcome aboard! We hope you will enjoy the community. Ciao

Hi all. I've been diving for about 4 years and shooting underwater for probably 3. I use a TG-7 but have an OM-1 for topside photography that I'm looking to get a housing for. Here's an album of some of my favorites I've taken with the TG-7

Despite the widespread availability of smartphones capable of recording high resolution video, the market for compact and specialized cameras continues to grow. According to data from the analytical firm IDC reported by the South China Morning Post, global sales of these devices increased by 20 percent during the first quarter of the year compared to the previous year. Shipments from manufacturing companies exceeded four million units. Until 2023, the American company GoPro dominated this sector. GoPro originally popularized the concept of wearable cameras designed for hands free recording, starting with a waterproof film model in 2004. Over the last three years, the market share controlled by GoPro dropped from 75 percent to approximately 6 percent. It has been replaced by two Chinese brands, DJI and Insta360. Together, these two companies now control 87 percent of the market. DJI alone accounts for more than half of total global sales. The decline of GoPro is accompanied by severe financial difficulties. In June, the consulting firm PwC raised serious concerns regarding the ability of the company to continue its operations, citing operating losses and negative cash flows. Furthermore, in April, GoPro announced the dismissal of 23 percent of its employees. This followed a previous workforce reduction of nearly 20 percent during 2024. The success of Chinese companies is largely attributed to their direct control over local supply chains. This allows them to customize components at competitive prices. The shift is not solely based on offering cheaper products. Certain GoPro models, such as the HERO13, are priced similarly or lower than competitors like the DJI Osmo Action 6. Instead, DJI and Insta360 have invested heavily in research and development. They equipped their devices with advanced sensors and chips to close the technological gap. Technology review websites such as TechRadar, Gizmodo, and The Verge confirmed that recent devices like the DJI Osmo Action 5 Pro offer superior battery life and better waterproofing compared to GoPro alternatives. DJI and Insta360 adopted an active market strategy by releasing numerous new products each year. GoPro maintained a much slower release cycle. For example, in the 360 degree camera niche, GoPro introduced its first device in 2017 but was quickly surpassed by Insta360. Market data from the Japanese agency BCN shows that DJI and Insta360 controlled 78 percent of the local action camera market in 2025, leaving GoPro with 18.9 percent. In the 360 degree segment, Insta360 holds nearly 60 percent of the market compared to 10 percent for GoPro. The current difficulties are also linked to past strategic errors. In 2015, the GoPro Session compact camera failed due to high pricing. In 2016, the Karma drone experienced critical technical failures during flight. These issues forced GoPro to exit the highly competitive drone market entirely, a sector already dominated by DJI. The rise of these Chinese brands has led to several legal and political disputes. In 2024, GoPro sued Insta360 for patent infringement. The International Trade Commission ruled in favor of GoPro on only one design patent while rejecting claims regarding internal technologies like image stabilization. Consequently, Insta360 can continue selling most of its cameras in the United States. In December, the Federal Communications Commission placed DJI on a list of technological companies considered a national security risk. This measure bans the import and sale of new DJI drones in the US but does not affect existing drones or DJI cameras. Finally, in June, DJI and Insta360 sued each other over design similarities between the Insta360 Luna and the DJI Osmo Pocket 3.

Ah yes! I saw your creations here https://waterpixels.net/forums/topic/671-proven-3d-printed-parts-for-underwater-imaging/ Super useful and I will definitely be printing the TC zoom gear version for the 8-15 and the 24-50 zoom gear too when I pull the trigger on the Z5 II...

Great video for a first attempt! I plan to try video with my E-M10 next week in Lembeh with my 60 mm and 30 mm macro lenses (30 mm for blackwater). Wish me luck. I sent you an IM question about your upgrade plan. Evan

Has any used the Sony 16-35GMII combo with the wacp-1? I mainly shoot wide angle doing sharks and people in blue water.

thanks for the advice strobe definiely made the images better I'll submit a few more when I have had time to sit down and process in LR

Yes, i use that TC on the Z8. Everything works great.
