Depth is a relative and non-essential factor; instead, you need to study the seafloor topography of the area where you plan to dive. The 75 cm arm is unnecessary. Dive lights must be securely fastened to the buoy line, using one of the many available solutions. Furthermore, for your safety, it is crucial to check the currents at the dive site: it is easy to get lost if there is a current, especially when you are focused on taking photos after finding a subject. The buoy must be highly visible, even if a skipper is following you. Always carry backup lights with you. Overly powerful lights are not necessarily important: 5000-7000 lumens are more than enough. Finally, make sure the battery life is sufficient to last the entire dive.

Someone forgot to clear the lint trap filter? This is a very common cause of fires!

Thanks! They were very safety and fire conscious on Explorer too. My understanding was that the fire was caused by a 3-month old dryer. It was made by a well-known European appliance maker. In fact our apartment has several appliances of that brand. But no dryer…..

Hi all, I want to start doing blackwater diving in my hometown, we have the proper boat and the lights, but I'm not sure how to organize the lights line. We are planning to go to a site almost 100 metres depth and place a line with a big buoy on top, 25 meters long line with weights on the other end, and with an arm 75 cm long with a powerful light on each end every 5 meters. Our plan is to leave the line in the sea for a while and dive with the boat skipper following us close enough to take care of ourselves. Do you think is the right way ? or am I missing something ? It's our first time doing blackwater diving

Regarding housings for the new Sony A7R VI Marelux has developed a user installable (one) part change that will allow the A7R VI to be fully usable in the new Sony A7 V housing. This new housing ships with the latest updates which allow you to install the FlashFuel2100 which is both a manual flash trigger and battery bank which connects to the camera via USB-C greatly extending battery life. The FF2100 allows manual flash triggering up to 20FPS. The remote shutter module can also be added for remote camera triggering up to about 10 meters away. This housing retails for $3398.00 in the US. The upside to this housing is that with one part change you can have a 66.8MP primary camera with the excellent 33mp A7 V as a backup for extended travel.

My latest update on Marelux optics is that Aquista 135D will begin shipping in July, MacroView 60 will ship in June and the new 180 degree optical viewfinder has not yet been given a release date.

I make some pictures from the little scratch.

This is raising my hope! I would love to be able to produce a video like this!

We were on a 'sister ship' the emperor virgo. We were dropped off at 7 the morning of the fire and only learned about it at a layover in Delhi. Just read that you were on that boat Tim. Glad that everyone came off it safely. Any idea what caused it yet? On the Virgo they were very safety and fire conscious.

Priceupdate: 1000 Euro for the Port

Priceupdate: 130 for the extension

This is what I got years ago with the LX100 (mark I) and CMC-1 I think on video. It's 4K that I cropped to Full HD and then stabilized.

Selling an AOI FLP‑06 flat port in solid working condition. The front element is glass. It has very light surface marks from normal use — they’re so faint I can’t get them to show in photos, and they do not appear in images underwater. No cracks, no deep scratches, and no issues with sealing surfaces. Includes: • Front cap • Rear cap • O‑rings (good condition) Condition Notes: • Light cosmetic marks only (too faint to photograph) • Optically clean in water • Mount interface smooth and secure • Always rinsed and stored properly Compatibility: Correct flat port for the Olympus 14–42 EZ and other AOI PEN‑mount flat‑port‑compatible lenses. (New price typically ~$199–$219.) Reason for sale: Reorganizing my port lineup. Price: $120 + shipping Located in San Antonio / Shavano Park, TX PayPal G&S preferred

Thanks for the catch — you’re right. The FLP‑06 uses a glass front element, not acrylic. The marks I mentioned earlier are extremely light surface marks on the glass. They’re so faint I can’t get them to show in photos, and they don’t appear in images underwater. Everything else in the listing is accurate.

Accepting reasonable offers.

Not this nice. There are tools extracting frames from video but many challenges - white balance, loss of detail, unsharp... but you can try and see.

I was thinking to test the Divevolk camera link with new Mission pro, the GP3 might be fast enough for 4K live preview (low latency) since is supported. https://community.gopro.com/s/article/GoPro-Quik-Live-Preview?language=en_US

The L10 has a different sensor (many say it's the GH7 sensor) without extra crop: f = 10.9 - 34mm (24 - 75mm in 35mm equivalent in 4:3, 3:2, 16:9) (28 - 88mm in 35mm equivalent in 1:1) https://www.panasonic.com/uk/consumer/cameras-camcorders/lumix-digital-cameras/premium-compact-cameras/dc-l10.specs.html

https://waterpixels.net/forums/topic/847-housed-smartphone-as-a-budget-monitor/#comment-3662 I actually bought this Divevolk solution after having terrible experience with Weefine's WED7 couple years ago. The problem with workarounds like divevolk is that they do not tend to work when one would need them. Forget about the lag, it's not that bad, the connection and the reliability of establishing it over and over - at least on Sony - is the real issue for me. So when I imagined logistics on a live aboard where most of my dives are with 3-4 dives per day checking the footage in between the dives - it was a real nightmare. Plus the element attached to the housing should be placed on acrylic effectively blocking access to camera monitor..

I use the CMC-1 on a LX10, which has a crop in 4K - so the 24-72 mm equivalent lens becomes roughly 36-108 mm equivalent in when shooting 4K video. It works great, and now that I have a flip adapter there is virtually no vignetting (40mm instead of 36mm). However there's a catch: you will need to get close to your subjects, veeeeery close. Shaun the Sheep and other nudis won't really mind, but other more reactive critters will, and lighting will also be tricky (not impossible, but takes a bit of getting used to). On the LX10, I shoot macro only in MF, using focus peaking. These are the working distances I measured at different focal lengths with my diopters on the LX10 in 4K on the AOI double flip adapter I now use. I tried to measure working distances at 36mm (choosing the minimal focal length to avoid vignetting otherwise), 50mm and 108mm equivalents, 4K, f/11. Working Distances on the Lumix LX10, diopters mounted on an AOI double flip, 4K video — NO DIOPTER f11 36mm min: glass <10mm max: infinity 50mm min: 90mm max: infinity / > 260mm 108mm min: 170mm max? — AOI UCL05 LF +6 f11 (vignettes to 55mm) 55mm min: 10mm max: 450mm 108mm min: 90mm max: 200mm — INON UCL165 +6 f11 (no vignette) 36mm min: glass max: infinity / >220mm 50mm min: 30mm max: 210mm 108mm min: 75mm max? — AOI UCL09 +12.5 (vignettes to 55mm) 55mm min min: 15mm max: 90mm 108mm min: 45mm max: 88mm — NAUTICAM CMC1 +15 (vignettes to 40mm) 40mm min min: 5mm max: 60mm 52mm min: glass / 5mm max: 60mm 108mm min: 37mm max: 54mm As for some actuall examples of high magnification footage using the CMC-1 on the LX10, here a couple recent ones. if you know these critters it will give you an idea of the magnification range. (I do have some Costasiella / Shaun the Sheep shots but nudis are not my favorite subjects for video, so I haven't done much with them. But yes, possible, at least on the LX10 with its cropped 4K - stills might be a little different). Need to see how this would work uncropped on the L10... Hairy Shrimp and Skeleton Shrimp (CMC1, possibly stacked with a +6 on some shots, can't remember) Green Turnicate Shrimp (really tiny - this was stacked CMC1 and +6) Ryukyu Sea Dragon (same size as a Lembeh sea dragon) Emperor Shrimps (slightly bigger subject) Skeleton Shrimp and Juveniles (these are older shots, from my time in east Bali) Hope this helps cheers!

The answer is in the port charts, Nauticam publishes this data for all their wet lenses. The CMC-1 and L10 covers a field 33 x 25mm approx with the CMC-1 and working distance is 51-72mm. So a Shaun the sheep at maybe 3-4mm long will fill around 10% of the frame. With the working distance of 50mm, getting more magnification with other wet lenses will be a challenge as it will eat into working distance. Diopters work by allowing you to focus closer. You can review the port chart to see what cameras allow more magnification - some of the Canon compacts will get you about 23x13 at similar working distance and the Sony RX100VII will get 16x10 at 90mm and even closer with more powerful diopters but lacks working room. The downside of the RX100 is the need to swap ports to get the best out of the lens with wet wide optics. The parameter here is the focal length of the lens, the longer the focal length the more working room and the higher the magnification with a given diopter. If you really want some magnification you can't beat a interchangable lens camera, the olympus 60mm macro will cover 17x13mm without a diopter 10 x 7.6 with a CMC-2 with 30-93mm working room.
