No problem at all. We are waiting for a forum upgrade to block video uploads as we have resize filters for photo uploads.

Please guys, just upload your video to Youtube and then link them in your post. Thanks

It would be another blow to my wallet! After so many Nauticam housings, I am considering a change...

All rumor sites are baffled that Panasonic will unveil its new micro four-thirds flagship mirrorless video oriented camera on June 5. The GH6 is declared out of production in Japan only two years after its release. We will only have to wait two days for official photos and features. for now the rumors report: Most features of the Lumix G9II (PDAF) internal RAW New 32bit float recording methods via a new XLR unit Large fan With the introduction of Phase Detection Autofocus and internal Raw format (to be seen which one, given the patent war on the subject) Panasonic seeks to repeat the huge success of the GH5 P.S. I'm afraid I'll have to break my piggy bank this time...

Welcome aboard, I hope you will find useful info! Ciao

Wow terrific shots Thanks

Bigblue? I know some pro who use them: https://www.fotosub-shop.com/3460-bigblue-lampada-bigblue-7200-lumen-120-5000k.html?id=3460&lingua=2

My bad, sorry, Delrin has nothing to do with floats. Mine was just an example of the difference between the real material and the trade name given by the manufacturers and patent holders. Another example, Plexygals is the trade name for Poly(methyl methacrylate) or PMMA. Returning to our floats, I often used Termanto, another trade name for a closed-cell PVC foam. From memory, I have used the one with a density of 75Kg/m3 that easily withstands 14 Bar. In boatyards they use it for the structure of the decks, which are then covered in fiberglass or Tek, and the scraps are usually thrown away.

Gentlemen, Do we need a cooling filter here as well?

Our cooling filter while we post in WPX

Divinycell is a commercial name for pvc closed ceall foam, exactly as Delrin is a commercial name fo Polyoxymethylene or POM. I had avoided going into the technical details of density and thus depth resistance since 99% of the people here are recreational and use Stix. You used a very good but extreme and therefore expensive version. I have used much lower densities that still resist 150 meters and cost 1/4. Also you bought a board the size of a door. We're talking about chunks of a few tens of centimeters here.

Basically all the floats we see (pro & DIY) are made of closed cells pvc or pet foam. Closed cells is the key feature as it doesn't absorb water. It's a very cheap material that automagically become expensive when you add the words "underwater photography" near to it 🙂 Problem is that normally is sold in 2m x 1m tables... This material is commonly used for boat decks so if happen you have a small boatyard nearby you could get some cutout for free... Edit: oh I forgot: it is perfectly cut with a small hacksaw or cutter and shaped with sandpaper as if it were balsa wood.

Nice job indeed. A good example for @shelbyrose out of curiosity, did you ever filmed with the EMWL? Any sample on the net? Thanks

Hi Robin, Any update? Did you solve the issue withe the lens? Thanks

Did you check the YT channel of @Puccio Distefano? The Dart Vader of UW Gopros in Italy 🙂

Just check the AOI version. Their WA version has a terrific quality on par with Inon at half the price

Yes, there is now a huge bibliography on the subject. Scorpionfish are also spotted now all over southern Italy and I expect them to go up to the Tyrrhenian Sea. Not to mention the fireworms (Hermodice carunculata) that have now arrived in Tuscany and beyond.

keep in mind that the Novus is very delicate. I mean that with the “heavy scratch remover” it takes quite a long time to thin a minimal scratch.

Yes from what they write, the front dome is acrylic and the coating is internal. So this is a good news. Acrylic surfaces can be polished easily. I have always used Novus liquid, but I doubt that such a scratch can be removed completely. Surely by rounding the edges the defect will be much less until it disappears once immersed in water. https://www.ebay.it/itm/253646751131 Be careful to work on almost the entire surface to avoid ruining the curvature of the dome too much. I have always done it by hand with great effort and hours of work. Perhaps you can help yourself with a Dremel or drill and a soft disk at very low speed without overheating the surface. If you use the Novus, you will always work with liquid 3 and only as a last pass will you use liquid 2. Keep in mind that liquid 1 is basically just a cleaner for glass and plastic surfaces. Judging by the extent of the damage you could also start with a regular polish for car headlights.

Exactly what I was thinking. My housing is smaller and lighter than the behemoths normally used for these shots so maybe a two point arm attachment to the housing 1" balls would suffice. Then adjusting the angle I could adjust the immersion level.

Welcome aboard! Un salutone dall'Italia! Looking forward to have some contribution on the action cam forum 😉 Ciao

Hummm it seems a huge damage. Scratch removal methods used on acrylic, usually don't work on glass which has its own techniques and methods. Even on a lighter scratch it's difficult or impossible to completely remove it but you can smudge it and that one it's a huge one. Regarding the coating, I'm nearly sure it's on the inner part of the lens, not on the outside.

Jokes apart... This is a good starting point. You are right, these rigs can be used only on flat calm sea conditions. But the pros have time to spare 😉

Hahahaha I'll start from this
