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:

I've recently came across a video on youtube about tips and tricks to shoot cinematic footage by any action camera. The YT channel is run by a couple creating mainly travel videos with lots of underwater sequences. The recommendations (use tray, add lights, get closer etc.) are totally appropriate but the underwater video sequences are just not OK and IMHO, and they are far from cinematic, or I just haven't seen that movie. My main problem is that they forced hyperview and the corners are somehow stretched and not sharp. Actually, only the middle segment is usable according to my standard. I left a comment, but in general other comments are positive. So the people are happy with those results. Most of the people will watch YT videos on smartphone, so maybe trying to reach cinematic quality is just overrated or the people's quality expectations are lowered drastically. I'm curious about your opinion. Please, don't leave negative comments on the video on YT, I don't want to bash their channels, so lets rather discuss here, and more as a phenomenon (with this particular example) general. By the way I think it's possible to achieve cinematic quality with action cameras as many footage in big blue chip productions were taken by action cameras. So here is the video I mentioned:

Nice job

I lost my cap for the Nauticam USB-C (see picture below) bulkhead. If you have by chance a faulty USB-C bulkhead connector with the cap and it just collects dust I would buy it for a reasonable price. I live in Germany, so it only makes sense to post it from Europe.

It won't short. I've tested it unintentionally, so it's not just waterproof but also your camera is protected in case of leakage (which is highly unlikely if you screw back the cap properly).

Yes, it's a video light
