I was toying with the same idea, but overall it's not that cheap. I was actually considering a cheap phone in an even cheaper case with DIY wifi connection (coax cable). However, I use Sony A6400 and the remote app (Imaging Edge) is just PITA to use. It would cause probably so much frustration underwater, that I decided not to try this route. Maybe somebody has a better experience.

I still think it was good to warm up this topic, because we know more about the Nauticam housing and maybe somebody already has some first hand experience.

I mainly focus on underwater videography but sometimes I could use some good quality still images. Couple of months ago I saw a video (see below) about using video files to make high resolution still images. I'm quite convinced:

It would be interesting to see a comparison with the original Invisible Dive Case Pro from Insta360. The price difference is huge (890 vs 140 Euro), so Nauticam case should offer something. It looks more durable and the dome ports are glass, but it also heavier (though more compact). For me a decisive factor would be image quality, especially handling stich lines and inner reflections. I'm not sure, if I would pay the extra cost of the Nauticam aluminium housing.

I've been using an Insta360 X2 camera for a while. During a recent trip I had the same dilemma to either use a GoPro (with AOI) or the 360 degree camera on the top of my mirrorless housing. Comparing the footage from both camera I can conclude that The GoPro has still a way better quality. However, I can still use few seconds of Insta sequences as interesting perspectives, but not too long sequences, because some optical errors (stiching problems) will be obvious. Another good use is to leave the 360 degree camera on a "tripod" in shallow water. For usable footage you need lots of light for the Insta cameras. New models are probably better. I wouldn't use it as a main camera but it can be a very useful tool. I use ot on a ball-head like below to attach to my main camera: Some examples for the videos with Insta360 X2 you can find in my short movie about Bali: 1:44 - 2:10; 2:41

Is there anybody a good printing solution for N85 focus gear for Sony 10-18mm f/4 (SEL1018) zoom on Sony a6400 (or similar A6xxx) in Nauticam housing (housing zoom knob). I'm totally noob for 3D printing but I have access to a printer and help.

They are colour corrected but not too much and not necessary final. However, complete removal of blue cast is not my aim. I don't like those clinically corrected videos, where the impression is that it's not recorded underwater. Long time ago I read an article about designing the Finding Nemo animated movie and they introduced underwater particles (backscatter) and vanished colours in far away subjects, just to be more realistic, underwater-like.

I used AWB on the Sony but I found that GoPro is better with fixed WB, so I tuned according to the video lamps, so I used 5000K, it makes wide footage more rich in blue. Maybe these subjects are not that colourful, but I see a subtle difference bringing out the colours well. This video below is a better examples for the colours of GoPro with external lights (more colourful subjects and available lights are less dominating).

It's interesting that you favoured GoPro footage. Have you watched it on phone or on a large monitor? I think it makes a big difference, but I agree that the difference is not that big and when the conditions are good for GoPro shooting with a large camera doesn't bring too much.

In shallow water or with proper light these action cameras can produce really good results, especially with the AOI (or Inon) wide correction lens. I always praised the close focus improvement by the AOI UWL-03 but it's more prone to show the particles close to the lens than the AF lens with shallower depth of field. Shooting towards the sun is also more complicated with the AOI but under ideal conditions I'm pretty happy with the results from the GoPro.

You can buy currently the GoPro set-up around 600 euro, while the cheapest wide-angle option for Sony A6400 (with this zoom lens) is 1750 euro when a Saltedline housing (400 euro with 6" dome port) is used and not the more expensive Nauticam case (there would be not much optical optical improvement going for the more expensive housing).

During my last trip to Raja Ampat I had the chance to compare a Sony A6400 with the 10-18mm f/4 lens to the GoPro12 with AOI UWL-5 wide lens for videos. My original plan was to use the Sony camera mainly for macro and have the GoPro setup for wide angle. However, most of the dives were more appropriate for wide scene videography. So I used both camera very similarly, therefore, I produced many similar footage, which is a good opportunity for comparison. I tried to max out both systems. Sony was on XAVC S 4K, 25p 100M, while GoPro was used with GoPro Labs (4K 60p, highest bitrate). You can see the setup below: I've uploaded two videos with many footage on my YT channel. The perspective is a bit different but they can be compared. There was a recent thread about the "cinematic" application of action cameras. I think the GoPro is not that bad but I observed many optical errors. What do you think about the results?

Sure, I also sold GoPro and even Yi 4K+ (old action camera) footage. My problem is that bad quality videos are promoted as "cinematic" ones, and maybe it lowers the expectation of the general audience.

I don't have problem with clickbait titles or thumbnails, since sometimes it's necessary to reach broader audience. I'm OK with it, I don't click just because of it. My major problem is that the videos sequences posted are really bad quality (some aspects) and it's sold as cinematic, which suggest higher quality and the audience are OK with it and they don't recognise that nothing is sharp. I also use GoPro in addition to my Sony APS-C mirrorless (A6400) and the quality from the action camera is not bad. Some short sequence I already posted on my channel from my Raja Ampat trip (maybe I should blur the corners):

I like Vu Nguyen's opinion about cinematographers:
