Re-reading @Edward Lai post I understand that the purpose of the lens is to improve the quality of the flat macro port. Early prototypes also had a slight magnification but the range of focus was prioritized. Thus: about the same magnification as the macro lens on which it is mounted greatly improved image quality bonus: extended range of focus Correct me if I am wrong

The Veretillum cynomorium is a colonial octocoral belonging to the class Anthozoa and the order Pennatulacea. This organism is anchored to the sandy or muddy bottoms of the Mediterranean and Atlantic, distinguished by its fleshy, elongated appearance and its ability to emit a faint bioluminescence. It is made up of a colony of polyps, each with specific functions, working together to feed and reproduce. Bottom trawling and fishing gear that touches the seafloor can destroy entire colonies, tearing them from the substrate or damaging their habitat. Additionally, climate change, such as rising temperatures and ocean acidification, can impact their delicate ecological balance, even through indirect effects like the decrease in plankton, which they feed on. To preserve this species and its valuable role in benthic ecosystems, it is crucial to protect the seabed with marine protected areas and promote sustainable fishing practices. The Veretillum reminds us of how fragile marine life’s balance is and how important it is to safeguard it. Shot on Lumix GH5MII, Panasonic Leica 45mm; CMC-2; lights: RGBlue + XDive

Prices of a used R5C keep falling and it becomes very appealing. Now there are a lot of "old" camera that are amazing video monsters. Few months and the OG A1 will fall under 4K€. Going back to Canon R5C, with the latest firmware upgrade, can do 8k 60p RAW with no external power and JUST the LP-E6P battery: https://www.canon.co.uk/press-centre/press-releases/2024/11/firmware-updates-add-extensive-new-functionalities-to-canon-professional-video-cameras/

Thanks, I guess it's impossibile to print that thread pitch at home. So I will buy a cheap 67-82mm step-up filter and I will print a ring that will fit inside.

Basically, from the Marumi table the same thread pitch as photography filters. Thanks

I'm asking a question, maybe a dumb one, so don't shoot me 🤡 I remember back in the days of the Nikonos, extension tubes had a stick and frame to have a sure reference as to where the camera would focus and frame size. I don't even know the exact name for it, but it is a vintage item that has no reason to exist today except in very special cases. Inon reworked this concept in part for its macro lenses for GoPro and even patented it. Is there something similar for flat ports for use with add-on lenses? Since I can't find anything on the net I got the doubt that my question is dumb. Yet there are use cases in my shooting where having an immediate visual reference if I have positioned the lens at the right distance from the subject would be very handy. And this fantasy object would be perfect. Here where I usually dive, many of the subjects I try to film in macro are on steep, muddy rock slides. Being able to position the tripod is already a feat, and clouds of mud rise with every adjustment. Sometimes I give up even before I press the REC button. Sometimes corals close polyps if illuminated for too long. Even under ideal conditions, the depth often does not allow me to waste too much time. In short, I see this as a likely DIY project. I imagine a 67mm ring with a mechanism similar to Inon's or simpler or even fixed, but where the stick is interchangeable. The size or references on it would change depending on the focus range of the additional lens used. The stick can also be a straw. For starters, do you have any idea of the standard thread pitch of the 67mm ports and add-ons? I have only found those for photographic filters: https://www.marumi-global.com/blogs/technology/faq-thread-pitch

Yes, then it is assumed that we always want to work at maximum magnification which is not always necessary or desirable. Then here we are talking about video while 90% of the examples are photos. Repetita Iuvant: it is one thing to stand still in the blue (black actually 😉) for 1/250 of a second, another to stand there for 30 seconds at 1:1 magnification.

Have a look here. This XAvdenturer seems a good option, a fair price and Pietro sell them in Italy. @Wags could give you his feedback.

Terrific quality for a such small camera. When you have time. Would you mind shooting something on the reef with fixed WB and Natural light? Thank you in advance

People think that gopros & Co. have special requirements for lights or given that the camera is "cheap" same apply for the lights. It's true the contrary. The tiny sensor requires a lot of light. A FF camera or even a M43 camera can work flawlessly at 1600 ISO and up. While a Gopro @1600 ISO is pure trash. IMO the only requirement is having something small. 6K is the bare minimum). There are the Scubalamp/SUPE very cheap (but iirc they are not constant output). A good option are the latest Kraken lights ( @bghazzal can give you some feedback) or Weefine.

A friend of mine bought it and he use it as plugin into PS He sent me a couple of photos never edited of a dive we made on the wreck of a JU 52 WWII airplane near Capri Island. Photo credits: Marco Bartolomucci

Absolutely not 🍻 In the end it is the market that decides. From the feedback I see around I think it will sell a lot of licenses. In the Blackwater scene they cry tears of joy 😹

Guys, let's try not to be so polarized. We are not on Facebook 😄 Everyone can make his own judgment. Besides, we are not 7 billion Tom Hanks in Cast Away. We are a society. I am a sw engineer. Should I be willing to pay any amount of money for a steak because I don't know how to be a butcher? Come on... Maybe before I stop diving, someone will come out with a similar plugin for video. A dream.

Is that the pancake 16-50mm lens? I thought it was smaller... It would be nice finding a printed gear. I guess the Nauticam gear costs double the lens price 🙂

Last week I saw a photo shot on the Thislegorm mooring in the evening. Something like 12 liveaboards on the same spot. Just imagine underwater...

I thought the same but I'm afraid it would have the same problem as the Lumix 30mm M43: too short minimum focus distance... This lens has a MFD of 95mm from sensor plane. The lens is 56mm long. Add 10 or 20mm for the port and you end up focusing on the glass to get 1:1. Despite everything (it is a very old lens) it seems that with firmware updates it has AF optimized for video. At least according to the Sony datasheets. However, I don't think it is possible to add diopters. It would take someone who has used it.

Update. 17 missing so far https://www.france24.com/en/live-news/20241125-egypt-says-17-missing-after-red-sea-tourist-boat-capsizes

I guess it's more or less like my M43 kit lens 14-42mm. It seems crap but behind a WWL-1B it's decent. This is A6700 + 16-50mm + WWL-C. I don't like its color grading but rhe results are perfect.

You just gave away a fundamental piece of the Japanese diving kit !

Congrats for your new Lady 👏 Looking forward to see some footage. Please, shot for us some clips in ambient light only 🙂

Thank you for the video. Finally a test that makes sense unlike what we have seen so far posted by web stars. On one thing GoPro is still ahead of DJI and Insta: user manuals. Can't find a table with the FOVs of the different modes. One of the few meaningful video: It is clear that ultra wide and maybe even wide are too wide to avoid distortion behind a flat port. but I think that is impossible even for lenses like AOI or Inon lenses. Not surprisingly, Inon has just introduced an updated lens. The correction you made shows that these files can be “pushed” quite a bit. Maybe a filter can help. @bghazzal has done several experiments and his solution seems to be very inexpensive as well. Lee Dark Salmon gel worths a try, a sheet is really cheap: https://waterpixels.net/forums/topic/1414-ur-pro-filters-info/page/2/#findComment-10509 I am looking forward to seeing the results with the AOI lens.

Does it come with the Neweer head or it's your addition? Is the head still "alive"? Thank you in advance
