various updates

Inspired by an old post, and now that we've got fancy tables for our posts, I've dived into creating this little list covering most of the monitors out there.

I see this topic is quite a hot one, and like many others, it pops up again now and then. I hope this can be helpful!

Please help me correct and complete it.

I weighed the SUPE UM5.5.

There is a slight error between the precision scale and the luggage scale, so it is not very accurate.

Since the baggage scale cannot be measured less than 1kg, it was measured by adding a weight and then subtracting the weight from the weight.

The weight includes 2 * 21700 battery and an inch ball.

Precision scale on Land: 1320 g

luggage scale on Land: 1.2 kg

luggage scale Underwater : 0.7 kg

Error approximately 120 g

SUPEUM5.5 seems to be the same as fotocore.

I received the monitor last week, and when I turn it on, the fotcore logo appears on the screen.

(Weighing in cold water, the fog in the picture is an external screen.)

Thanks for the data. You confirmed it is another brick 🙂

How are you finding it? What's your opinion? What's your use case?

Regarding Kraken monitors, they kindly wrote me that both the 5" and 7" went through an upgrade. Specifically the V2 versions of the monitor haven't changed in terms of function, but they do use 21700 batteries now instead of the big battery block so they are lighter weight and much slimmer than the previous versions. Hence:

• The 5” V2 monitor is 1680g on land and 260g underwater

• The 7” V2 monitor is 1795g on land and 230g underwater.

Table updated!

데이터 감사합니다. 또 다른 벽돌이라는 걸 확인하셨네요 🙂

어떻게 생각하시나요? 어떻게 생각하시나요? 어떤 용도로 사용하시나요?

Kraken 모니터에 대해, 5인치와 7인치 모두 업그레이드되었다고 친절하게 알려주셨습니다. 특히 V2 버전의 모니터는 기능적인 면에서는 변화가 없지만, 큰 배터리 블록 대신 21700 배터리를 사용하기 때문에 이전 버전보다 무게가 가볍고 훨씬 얇습니다. 따라서 다음과 같습니다.

• 5인치 V2 모니터는 육지에서는 1680g, 수중에서는 260g입니다.

• 7인치 V2 모니터의 무게는 육지에서는 1,795g, 수중에서는 230g입니다.

First of all, I tried using it in Underwater for a two-day monitor test.

Yes, it's a heavy brick, but it's comfortable underwater with the addition of a buoyant to the arm. The weight underwater didn't bother me too much.

I mounted the ball on the rear side, making it as close as possible to the camera housing, and set it to look in the 45 degree direction. (The rear screw hole is shorter than the screw in the component, so I added a washer to fix it without a gap. The design is a little strange.)

It's bright. The brightness adjustment can be wheeled from 1-100%, but it never went up more than 30% even in very sunny weather. I don't need 3000-nit brightness monitor is necessary.

I can't hear the cooling fan. I'm not sure if I removed the fan while waterproofing the feelworld monitor or if I can't hear the sound.

I'm 95% photo, less than 5% video. I only use mirroring. I only use brightness control for my monitor, and I don't need anything else. I haven't used it for wide angle shooting yet, and I used it for snoot shooting during macro shooting. The monitor was installed in the front of the camera housing a little bit, making snoot aiming a lot easier. Because physically my arms can go further.

The color of the monitor is not very important to me, but the color temperature seems to be a little low.

I saw complaints about monitor delay in other reviews, but I couldn't feel the delay on Nikon camera.

In the camera photo mode, the 16:9 of the monitor cannot be fully filled, but the intuition is increased by showing the camera setting values large on the black remaining areas on both sides.

The satisfaction is high enough to try the underwater monitor now.

The downside is that first of all, the cable protrudes to the left, causing the buoyancy agent and interference when controlling the arm. I'm a little worried about the durability of the external hdmi cable.

I have plan a two-week trip in dauin, Philippines at the beginning of next month, so I think I can tell you more about it after using The Long Term.

As a result of many searches before purchasing, supeum5.5 seems to be sold by changing the name not only in fotocore but also in Aquatech Housing.

Original post updated with product links, prices, and weights

Marelux just announced their monitor:

Doesn't seem to be much data on it as yet.

Yesterday, their website only had the photo and the page was empty. There wasn't even a name. Today it's appeared, but the rest is still blank.

As soon as they publish the specs, I'll update the list.

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 !

Hello @eocean-eu My native language is not English so my grammar may be wrong.

I have the same problem, but a little different. I have an old Nikon Z6/Z7 1st generation.

Video recording Mode is blackout-free regardless of HDMI output settings.

On the contrary, I have blackout (no signal) in photo shooting mode.

HDMI 1080 Output - After taking a photo, when the preview screen time ends, a blackout (No signal) message appears on the monitor for about 0.5 to 1 second.

HDMI 4k output - After taking a photo, a blackout (No signal) display appears on the monitor for about 0.5 to 1 second, and then the preview screen appears.

This is a really strange phenomenon. Blackouts appear differently depending on the HDMI output. This seems to be a characteristic of the Nikon camera rather than a monitor issue.

I tested it by changing the hdmi output because of @eocean-eu question. Since my monitor is full HD, I set the HDMI output to 1080. I found out that the blackout is different when testing 4K this time.

What I found out this time is that when I connect my camera to HDMI, I thought the camera LCD would automatically turn off. However, when I connect the monitor, the camera is automatically set to the viewfinder. Even if I set it to the camera monitor output because the viewfinder consumes more battery. When I wake the camera from sleep mode or turn it off and on again, it automatically changes to the camera viewfinder. It's very annoying.

This problem seems to be a Nikon camera problem, not a monitor problem. Although there are these disadvantages, the advantage of using an external monitor is that the composition and angles become much easier and more convenient.

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.

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)

The housing seems to be very well made, and I also see a lot of empty space for the battery, which might actually be a good thing. I'll try to find out more and update the table.

Wouah it's probably not the best, but the price are realy good

Opening post updated with new Seafrog monitor.

I got a reply directly from Seafrog with product data. Moreover the housing comes with a M24 or M28 bulkhead.

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.

That's exactly why you have the variation - buoyancy is equal the the weight of the water displaced by the monitor, the bigger it is physically the more buoyant, if you have more air space inside it is more buoyant.

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)
