Congratulations Alex! Beautiful shots and camera movements. The lighting effects are outstanding!

For Canon colors underwater I totally agree with you. Canon was the one that had a MWB and the most pleasing colors in underwater shooting. Now that is no longer the case. [rant mode on] I am sorry to see how 99% of the threads focus only on purely technical aspects and we all become pixel peepers. One forgets that cameras are not automatic drones but there is always a person using it and the purely artistic aspects of a video or photograph are neglected or almost taken for granted. In short I reiterate my signature. [rant mode off] In this regard I would like to mention that two very good video makers like Marcelo Johan Ogata (https://www.bugdreamer.com/) and Alex del Olmo (https://naucratesuw.com/) have been using a GH5 for years. Hard to say that their MWBs or colors were not up to the mark. There is always a person behind the camera. Now BugDreamer uses a RED V-Raptor and Naucrates a Canon C70. You mentioned the R5 and R5C, and in my opinion the C70 is missing from the roll call. It is an S35 cinema camera absolutely not to be underestimated. I point you to this follow-up review published a few days ago by CVP, a rent cinema company that produces very accurate and unbiased reviews. You could find old comparison and review about all of these cameras. I also point out this YouTube channel. IMHO this is a talented guy in both editing and color grading. His older videos are shot with a Canon 1DX then he used a A7SIII, a C70 and an R5. Canon colors in all their glory. For the R5 whose MK2 is rumored soon.... Initially, it had the well-known overheating problems (deliberately ignored by all the biased YT influencers) but then finally Canon largely solved them with subsequent firmware upgrades. I know at least one professional filmmaker who uses it in a Seacam housing as B cam along with a C500 MKII and the quality is insane. What to choose? I don't know but again it may be best to wait a few months, if not 2025. We all read the rumor sites and Canon has registered 5 new cameras with two of them soon to be released. I would stay in the window. P.S. Once the new cameras come out, there is also a chance to get some good deals in the used market...

Knowing where this thread comes from, or rather, because of what it comes from, I'll get straight to the point. You already come from the top-of-the-line Sony hybrid mirrorless. Speaking of other brands... RED It is perhaps one of the most widely used cameras in wildlife documentaries including underwater ones. Sony A7SIII are seen occasionally as B cams. Lately I saw Sony Burano or Venice in some BBC productions. Switching to RED, even considering only the cheaper Komodo X, is a huge financial leap. Not only for the camera body and housing but also for all the accessories that come with it. These are cameras that were created for cinema and therefore lack a whole series of features that are considered almost standard in the consumer market but in cinema are not, quite the contrary. (***) Autofocus in theory yes but in reality you have a basic AF only with Canon lens. Nothing like AF that current mirrorless users are used to. Let's not talk about Sony users. See this (https://www.youtube.com/watch?v=EEUDXliF-Us Even if the economic factor is not important, in my opinion there is another factor to keep in mind. As you know RED has just been bought by Nikon, and as much as both parties have made statements aimed at reassuring users and investors, it is unclear what will happen a year from now. Speculations range from "Nikon will take all the technologies and patents and goodbye RED" to the opposite: "A RED with all the Nikon technologies will come out soon, as Nikon wants to enter the film market." This is actually quite complicated. RED had sued Nikon for patent infringement regarding the compressed RAW format, and shortly after an unspecified settlement, Nikon bought RED. Just think that RED uses EF and RF mounts precisely because in return Canon was allowed to use the compressed RAW format. A fair exchange many say. But Canon is a competitor of Nikon. Many have wondered if at some future time the deal will be cancelled. Certainly in the future we will see REDs offered with native Z-mount. In short in my opinion by buying a RED now you risk seeing your investment depreciate in the short term. *** Edit: I correct myself, or explain myself better. Surely you can use a Single AF and focus on the subject and then try to stay as hyperfocal as possible. Pretty much what I've always done with my Panasonic. I don't know your style of filming. Some people use CAF and the camera may follow the subject. I don't think the CAF RED is as reliable in water. It would be interesting to get feedback from @Alex B who has long since switched to a RED Komodo.

According to Canon rumors a R5II is expected this month. Why don't you open a new thread on this? 😉

I am really very, very sorry. I read so many comments on the net of people with the same problem but it is hard to say what percentage are affected by the problem. Of course it is strange that an update would put so many pre-existing HW failures and all at the connectivity module. Sony is no stranger to such behavior and generally these giants only move if users unite in some way or fear reputation damage. I too have had similar problems in the past with Panasonic Italy. As expensive as they are and as professional as they are, these cameras are aimed at the consumer market and this is the way they do things. I would not expect different behavior from other companies.

I film with a completely different system: MFT but this association is similar. I use the kit lens with the flat port. A 14-42mm (FF 28-84mm) to which I attach WWL-1B for wide angle or a CMC-2 for macro. I never thought of removing the WWL in water. Too dangerous for the diving I do but I know some do on shallow bottoms that allow it. I use the CMC-2 with a flip adapter. This is a great setup to have more flexibility and not be tied exclusively to macro. With just the 14-42mm I can take portraits of fish or even small whole fish or corals and by adding the CMC I can switch to macro. However, there is one small detail to keep in mind (which I admit I missed at first). With an additional macro wet lens you can focus only in the small specific range of the lens (80-120mm for the CMC-2 in this configuration). So it's not like having an actual macro lens that allows you to focus (in theory) at any distance. Maybe my point is superfluous and may not be a limitation. It depends on the type of subjects being photographed/filmed. When I want to engage in macro I prefer to mount my 45mm Leica (90mm FF) and optional CMC-2 on flip adapter. P.S. Of course as @RVBldr wrote, Murphy's law is always lurking and a GPO always appears when you have the wrong lens. In my experience here in Italy, never never never mount macro lenses in the spring. A one meter anglerfish waits calmly for you expecting an entire photogrammetry session to take it all in 😁 A 4K frame of her, taken with the 45mm PanaLeica.

Terrific resource!

It's pretty heavy but I see that on the back there's plenty of space for a pvc float.

Still very expensive thought 10 orings of that type in an hardware store don't add up to one dollar. I have never understood why manufacturers of various types of diving equipment continue to want to make money on o-rings. A set of o-rings from my previous rebreather from the manufacturer: 100 €. At the hardware store 10 €.

Don't you a friend who can borrow you a battery to test? IIRC Gopro batteries are the same until the GP9/10

Didn't you find anything useful here?

I have a GP5 and a GP11. Both start with an external power supply but IIRC the GP5 wants a working battery inside. So as Tim suggested, it could be a dead battery.

We have the same problem in the Mediterranean as well, and there are several projects, sites and groups on SNs where we report these sightings. The main source is the Suez Canal where several species transit from the Red Sea. They used to remain confined to the south. Now with rising temperatures they can be found further and further north, and by now some areas of south of Italy are tropicalized. Scorpion fish, Comb fish galore. Now fireworms have arrived in Tuscany. https://en.m.wikipedia.org/wiki/List_of_Lessepsian_migrant_species
