YouTube quality issue ?
I am also a vimeo plus member for probably 10 years. At the moment, the real dealbreaker for me to leave Vimeo would be the inclusiion of ads which I found super annoying on Youtube.

YouTube quality issue ?
Indeed. The problem with Vimeo is mainly their search engine has been disabled in Europe. You can still access all the features if you have a VPN pointing to the US or it seems to work if you have a direct link to the video. The base link for the search engine outside Europe is vimeo.com/watch with all the things we used to have but in Europe you land at the root of your own page and that's all. To quote them about that change: Q: What specific features are impacted by these changes? A: Vimeo no longer organizes or promotes individual user-uploaded videos on Vimeo.com in the EU or UK. As a result, certain features available in our Free plans are no longer available on Vimeo.com in the EU and UK: Searching Vimeo is now limited to video content within your own Video Library. Channels, Groups, Categories, and other curated video collections, including Staff Picks, are no longer accessible. My Feed is no longer accessible. For Hire is no longer accessible. Although some features are no longer accessible in these regions, you continue to retain full ownership and control of your content. You can still share and embed videos on your websites and social networks. I must say that I could not care less about what the European Film Academy is offering on vimeo especially in regards to underwater video filmmaking. There is simply nothing.

Canon R5 Overheat / Nauticam Housing
I don't know which housing you are using but Nauticam sells an active cooling system for the NA-R5II housing. It's bascially an expensive set of one or two electric fans and a battery box.

Using focus ring in macro
With most camera having now focus assistant like on-screen magnifier or even better peaking options, IMHO fine tuning the focus on your subject manually can make a big difference between an okay and a superb picture. I shoot macro video. I use manual focus most of the time rather than autofocus (the only notable exceptions are for me blackwater and wide angle on wrecks).

Nauticam new UW monitor - yay or nay... (rant)
Setting your output signal to match the resolution of the monitor is the way to go otherwise you might get a black screen in certain shooting mode or take longer time. There are exchange of list of available/usable resolution between monitor and camera. It's called EDID. Whenever something is set to auto on one end, it takes longer. Yet, it's still not always sufficient on certain camera to properly reduce blackout time.

Oh No! I Scratched my WWL-C! Now what?
A Nauticam service center can replace the glass.

Preview of the MFO-2
Normally yes as Nauticam is very consistent to offer bayonet and M67 on their macro lenses. On the initial picture, it is mounted on a M67 flip system.

housing-mounted hydrophone
Depending on what your are filming, you may consider - if that's possible for ypu - putting the housing on a tripod and step away by a few meters once you have framed your shot and started recording.

housing-mounted hydrophone
I don't have experience with housing mounting hydrophone but some with hydrophone hanging in the water. I am using an Aquarian hydrophone. I suspect you can get easily interfering noises just by rubbing the housing, by the autofocus if it's in auto, even fan if your housing or camera has some. If the hydrophone is directional and let's say mounted forward; it could be better. When hanging the hydrophone in the water, I get noises of me rubbing the cable up to 1-2m from the hydrophone.

List of Underwater Monitors
Yes (I am doing this kind of calculation quite often for my job :) ) but I tend to think some values are a bit optmistic for watertight by design monitors as there is not a lot of free volume inside so I am a bit surprised as far as 2/3 of the land weight vanishes thanks to Archimedes thrust for those units. It's also worth noting the weight of the attachment system might be substantial (another clamp + pair of ball ends or swivel system)
-
List of Underwater Monitors
I am surprised on how various brands can get land weight at around 1.5-2kg for only 300g underwater. Those numbers may be acceptable for solution with housing for monitor like the Seafrogs unit where you get lots of volume inside but I doubt this applies for monitors watertight by design since they are super compact with little volume for air inside.

List of Underwater Monitors
Along the exotic brands of housing for exotic land monitors, I've found Seafrogs actually makes an aluminum housing for the Shimbol M5 (you can find it on Amazon). The cable looks nice and it requires an M24 port on the camera housing. There is no indication of size and weight (aside from the land monitor unit) https://www.seafrogs.com/products_details/1293270225312227328.html

List of Underwater Monitors
Thanks Edy for your detailed answer. Yes it's definitely a Nikon thing. I don't have any problem with my trusty GH5s which works just perfectly whatever monitor I hooked on it (underwater or on land). Those blackout/rescaling is something worth considering for someone who may want to buy a monitor. It's worth also noting some camera only turn on HDMI on in playback mode. It's never happening in the high-end range of products but I remember a friend buying an used SmallHD monitor and housing only to find out it was not working underwater. Long story short: read the camera manual before spending thousands of euros/dollars on a U/W monitor.

List of Underwater Monitors
Thanks for the detailed review. Regarding the comments on Nikon (which is an echo of my complaints with the Z8), As the problem is not happening in photo mode, by curiosity, would you mind trying to see if the monitor has a long blackout in vdeo mode when stopping video recording or going from live view into menus ? Thanks !

New SUPE/Fotocore Rm5.5 monitor
To be honest, since HDMI underwater cables have a long history of being fragile whatever brand you use, the sideway exiting cable is probably providing less strain to the cable than the up/down usual location of connectors (the other alternative is monitor with back straight output). I see that as an improvement in terms of durability but on the other hand, yes it eats side space which might interfere with arm location/handle.

Nauticam new UW monitor - yay or nay... (rant)
Only with the 5" . The 7" has a small blackout (1sec maybe) but I do not consider this lag to be a problem. And again, the issue is only for video shooters, not photographers.

Nauticam new UW monitor - yay or nay... (rant)
I've tried all the resolution and there is something odd in the Z8 HDMI behaviour as it seems to switch back HDMI resolution whenever you stop recording or go into a menu in video mode... while being super consistent in photo mode. Whenever resolution change, a new EDID handshake is done between camera and monitor. If the monitor is slow to do the handshake or has limited choice of resolutions, you'll get temporary or permanent blackout. The most common resolution that will work for any camera is indeed 1080p60 but even that seems to be a slow boat for the combo Weefine 5 and the Z8. I've also tried with an HDMI EDID dongle to see if I could force the handshake process with no luck. On the other hand, as you did with your A1, I've never had any single issue with my GH5 on 1080p60. It's a pity because the Weefine 5 is a nice little unit to travel with in comparison to the bulky 7inch TV set :D . The Nauticam one won't be better for sure on that point.

Nauticam new UW monitor - yay or nay... (rant)
Aside from being made by Nauticam, there is IMHO nothing really exciting so far about this monitor. Nauticam has not even bothered including batteries in this setup and cables. Both will increase the price sharply. The monitor so far has nothing that makes it a game changer, no internal recording and we do not know yet the supported resolution. I am using 5 and 7inches Weefine monitors on the GH5 and Z8 and while they works flawlessly on the GH5, the Z8 has long blackout with the 5inches in video mode (lenghty EDID handshake apparently) tberefore I wouldn't buy anything before having a good idea of the supported HDMI resolutions in the manual. At the end of the day, you get more features with a Ninja with its dedicated Nauticam housing for a substantially lower price.

Photographic Gear Prices in USA after Trump's Tariffs
Everybody is likely to pay more wherever you are because for any international business, this becomes a "challenging economic environment" when you might lose a big portion of customers in a region while not getting more in others. It's clear that to maintain benefits you'll certainly have to increase prices at least a little everywhere or to find other ways to reduce costs of manufacturing. In Europe, Brexit has been for me a good example of a lose/lose situation. I used to order for my job parts from big companies in the UK because they were made there. After the Brexit, it was a hassle and costly because of customs to get those. Some manufacturers among others opened some warehouse in mainland Europe. Others just didn't have the resource for and I now rarely order from them. Now the prices for those parts for those companies that have now offices in both side of the Channel are about 200% what they used to be before Brexit was effective. Aside from the rising costs since Covid and Ukraine, those companies had to buy/rent warehouse, deal themselves with customs or make assembly lines in Europe. It costs money in all cases and it has to be absorbed by the customers at the end of the line.

Nauticam WWL-1 hard cap - use on the boat? it has no lanyard attachment
It makes sense to keep the lens cover when you are in the water and wait for a crewman on the boat to give you or get your camera on board. At that moment, it can be easy to damage the glass or port. A neoprene cover like for other nauticam port could be a less bulky solution.

Do people still care about Photography Competitions?
U/W Competition is actually a word that describes different things. Your image can be judged at: - dive shows - online scuba contest - online U/W image competition - film/photo festivals - actual underwater competition/championship where you dive and then immediately submit your work. All of them are vastly different and the criteria to win are different. And since there are no real standard rules for a given category, it also adds some variability in the outcome. I've been modestly doing UW films and a few of them have won in the 4 first categories. I was also part of a national team some years ago at a CMAS underwater championship. I have mixed feelings about all this competition things but yet enjoy doing them. Here is a summary of my thoughts on this: ** The neutral ** - Don't do this for money and don't expect visibility there might boost a career or fame. It might have happened in the past but since bringing U/W is super easy nowadays, standing out of the crowd is getting harder and harder. Most contests and especially festivals do not provide any cash reward. You sometimes get goodies, occasionally a partially paid trip, some free dive somewhere but that's all. - If you want to have pictures properly evaluated, don't submit them to contests part of dive shows or any online contest where voting is public because it's like when people post badly framed pictures on FB and their friends tell them those pictures are amazing. Some people will ask their friend to vote for them. It makes sense to them to get a prize but it's not a good indicator of the quality of their work nor the work of other contestants. - The most serious UW championships tend to me to be more like ice skating competitions where your pictures are expected to match arranged criteria to make points with an imposed theme, imposed dive schedule and post-processing. Pictures are excellent technically speaking but often tend to be creatively dull because of all these constraints. It's perfectly normal but this is something that can be hard to fully grasp. Other championship are more relaxed on rules and are more focused on divers having a good time. ** The ugly ** - Sometimes contestants can go too far as they manipulate the scene or animal to get the perfect picture. This is not limited to diving but wildlife pictures in general. There is a problem when subject taken is unlikely to have the common behavior or to be at its usual location. They are many pictures online of "free falling open-water octopus" (aside the blackwater ones which are normal) or swimming animal that usually rests on the bottom. It's always frustrating to see those kinds of pictures winning where one would expect the competitor to be disqualified. - People can go as far as cheating in any thinkable ways at any form of contests. That's why sometimes raw pictures are asked by the judges. That's why cards are cleared, WIFI disabled, time stamped differently at actual U/W championships. Yet, some people try to submit pictures that not belongs to them or upload stuff before the dives... and they often get caught. - Sometimes some judges are just clueless and completely miss the first point or they are just part of the dive industry with little experience on judging pictures and sometimes there are not even divers and are judging UW picture... Comparing different photos/videos with sometimes different topics between competitors is tough job so you would expect to get some professional U/W image makers in the panel with some knowledge on biology. Those guys exist and some competition are judged by those guys but it's unfortunately far from universal. ** The good ** I kept the good for the end because it's probably the most important and what makes me still want to "play" at competitons: - it's nice to compare your work with what other do and any award is somehow some signs you're making good quality images. On the long run, it's a good record of your progress and each award raises your own bar to another level. - Actual UW competition are nice to meet other folks who shares the same enthousiam for image making. It's an occasion to share and learn and develop friendships. - Festival (especially nature ones) are great to show people the beauty of the ocean and to pass some take-home messages about threat and conservation required to our playground.

Anyone Used The Laowa 60mm f/2.8 2X Macro Underwater?
I don't own the 60mm but I've just received the Laowa 58mm in Z-mount format. For the 58mm, I don't see any major issue for underwater use for the few tests I've made in regards to distance. Focus for the 2:1 magnification is very close to my port (N120 macro port 6 + 50mm extension) at 2-3 cm / around 1 inch in air. As you mentioned, it's a fully manual lens that I will use with peaking activated. I've made a 3D printed focus ring for it for my Nauticam housing. I don't know which port you use on your Sony but one way to get aperture control would be to use a port extension with knob and design a ring for the aperture and one for the focus. That is my current plan (the 50mm extension can be fitted with a knob).

Weefine WED-7 External Monitor
I don't know what you imply with "with my vision" but if you suffer like me and many aging people of presbyopia, you'll still need some corrective lenses on your mask because whatever size of screen you'll get, it will be blurred. I have prescription lenses and one day I forgot my mask and borrowed a standard mask. Manual focusing on subject even with peaking enabled was complicated... Regarding the cable, having a spare set is to me important to have for any distant trip.

Weefine WED-7 External Monitor
I have both the 5" and 7". I use the 5 with my GH5s and the 7 with the Z8 as there were blackout on the 5" with the Z8 each time after I stopped recording video (the photo mode has not this issue but it's a Nikon issue as it also affects other brand of expensive monitors...). I prefer the 5 as it is more compact despite the total lack of controls except on/off. The 7 is a classic cheap monitor with many options/buttons such as flip screen, etc... Brightness was okay in shallow waters in Lembeh but not exceptional but still very usable. The 2 x 18650 batteries in the Weefine 7" are enough to do 3 x 70min dives. The design of the 7" has slightly changed I think in 2023 with a better shade, new cables. Weefine cables were previously junk as they tended to break easily. They have a new design that seems better but still the cable is thin in comparison to Nauticam (which also used to break). Time will tell how durable they are

Constant output video lights
Thanks for the links. The last one concludes 'If you have a flashlight with a single LED single lithium battery then get a Linear driver. If you have a flashlight with one or two NiMH/Alkaline batteries, then you need a Boost driver. If your battery voltage is much higher than the LED voltage then get a Buck driver ' A recurrent design for lights with several LEDs (not the single COB design) of the same color is to assemble them in serial. It has several advantages in terms of light quality, effeciency, safety, design but with a major disadvantage that when one led breaks, all the matrix is dead. A diode might break when cooling is not sufficient as it may break or unsolder. If one looks at a high power LED datasheets, there's a fair amount of data and information regarding cooling. The thing is the added voltage of all LEDs in series in divelight in many cases exceeds the total voltage of the battery pack. This puts boost/step-up drivers as the preferred choices for big divelights.
