  1. Humm I have a mix of Tim and SwiftFF55 view. Maybe it depends on forum personal settings. IIRC happened something like this when we started the forum and we posted an how to... Let me check
  2. On newshooter they conied the term Nikomodo for the new Red Komodo 🙂
  3. This is the rule #1 when using an external monitor with any camera. Disabling audio channels on hdmi output gives me a zero lag on my GH5 and GH5M2. Same for my buddy with a GH5S. We both shot only video and i wish I could have a 1000 nits Shinobi I did not understand anything about the problem with Slog PP because I do not use Sony and I don't take photos 😇 Shooting video underwater without an external monitor severely limits the ability to edit the image composition and in some cases it is simply impossible to shoot certain footage without damaging the surroundings. This is the pure and simple reality.
  4. Has anyone designed or printed the back cap for Nauticam N85 ports? I've just lost one and it costs a lot. For now I am using a flexible silicone cap 🙂 Thanks
  5. Naive question For the past two years I have used almost exclusively the anonymous Lumix 14-42 mm lens coupled with the Nauticam WWL-1. Lately I have had a chance to reuse the Lumix 12-35 mm and 6" Nauticam dome and I noticed that the stabilization of my GH5M2 is much less effective with the 14-42 mm + WWL combo. Could it be because the WWL alters the focal length of the lens a lot? For manual lenses, the GH5 allows you to set the focal length manually, which serves precisely the stabilization algorithm.
  6. Yes, these lenses didn't change since the Gopro 4. I did not study optics either but those sensors are so tiny and works hyperfocal. Maybe the new insta is a little bit different with its 1" sensor. Gopro is the market leader so everything revolves around them. Inon still mentions obsolete Sony action cams. The real truth 😄
  7. I see a lot of conspiracy on the net and read a lot of speculation about this news that has indeed left everyone stunned. I add my own... I see nothing mysterious in this. Nikon just before the move to mirroless was almost given up for dead (it had just lost a very important piece of its business in lithography of electronic components). Now it's out of the picture, but I don't think its Z line has changed things all that much. So in a very high-tech market with a very small (declining) number of units sold, it is increasingly difficult to find the funds for the necessary technological investments. Sony has a diversified business and can rely on revenues and technologies from so many other markets. Red in my opinion did not fare any better. It remained a mystery to me how such a small company could make a living in this industry. Where was it getting the money for technology investments. By the way, in Europe Red was getting progressively gnawed off the market by Arri and Sony competition is hard. So big fish eat little fish. It's a win-win deal for both of them even while keeping their respective brands separate. The exchange of technologies will be there. Even without fantasy Red by Nikon stickers or the like. Nikon acquires several patents and technology (raw and global shutter) and enters the cinema market. Red accesses Nikon's technology and more of its production capacity. If in a few years we essentially have a Nikon camera inside a Red cube marked Red no one will ever know. Then of course there are a whole series of probable ripple effects in the patent war and on trade agreements with other brands.
  8. Davide DB posted an article in News
    Nikon is aiming to broaden its presence in the cinematography industry. The company has disclosed its agreement to acquire Red, a cinematography camera manufacturer, which will operate as a fully-owned subsidiary of Nikon. Details regarding the terms and value of the acquisition were not revealed. In its announcement, Nikon expressed its intention to utilize this acquisition to expand its footprint in the rapidly growing professional digital cinema camera market. By leveraging the strengths and networks of both companies, Nikon anticipates an innovative future in product development that will push the boundaries of film and video production. Nikon's proficiency in product development, reliability, image processing, optical technology, and user interface, combined with Red's expertise in cinema cameras, including unique image compression technology and color science, is expected to drive the creation of distinctive products. Here the full press release: https://www.nikon.com/company/news/2024/0307_01.html
  9. There is the AOI-UCL-03. It' not a rela macro but a close-up lens. The sister wide angle lens is excellent. AOI and I non lens use the QRS-2 mount. I see that both Easydive and T-housing have a Inon adapter for their gopro and dji osmo housings. I guess it "ShouldWork" even on AOI lens... It's a simple system and designing and printing at home a mount for the Insta one should be pretty easy. https://www.easydive.it/en/accessories-for-underwater-housing/accessories-for-housing-action-cam/additional-lenses-for-action-cam https://www.aditech-uw.com/en/shop/cat-238-307-767.html
  10. It was released a few days ago, a really well-made short film with very beautiful cinematography. From the synopsis of the film: Four years ago, Patagonia produced another feature film about salmon. This one is a real punch in the gut.
  11. From Youtube author's comments: @Barmaglot did you do blackwater in Andaman sea?
  12. Maybe @bghazzal can give you some info 😉
  13. Where was the photo taken?
  14. Which kind of fish are those? Sturgeons? Initially I thought they were sharks 😵
  15. Hi Brett, welcome back to the bright side 😉
  16. Welcome to the club 😞 In this case I believe it is because the lens has 10 times the surface area of the gopro and consequently the likelihood of picking up material in sediment-rich waters such as rivers and lakes is much greater. Also the fact that it is a wet lens exposes it to the known problems of other big sisters such as WWL and EMWL. Then in my case something else happens inside the gopro... Sorry I did not shared any other example but therlse are very busy days.
  17. So you are lucky that you don't have to spend all that money 😉
  18. Not by default. We should arrange some DIY attachment.
  19. This could be an explanation. Maybe the front 52 mm adapter and wet lens reduce the heat exchange. Good to know then. I couldn't find any reliable source stating it. Problem is that trout spawning last about one month so there's no time to experiment. I got the AOI lens few days ago and the next full moon everything will be over.
  20. Actually in the subsequent test, we never found fogging on the gopro lens... only the first time because I dislogded it by mistake. I would have tested it without protective lens but I couldnt find reliable info on being 100% waterproof. Someone says it's waterproof but not as before. That's means nothing to me. BTW given that my wet lens holds on the gopro protective lens, I should remove the glass and keeping the frame. Mistery
  21. Angle warping while panning is an extreme FOV consequence too. Even with my WWL-1 I get warping if I pan in full wide. I always zoom in a bit for a moving shot. IMHO the safest FOV for panning is that of a 24 mm lens. I should also see the same effect on other Gopros used with the Digipower and instead it only happens with the AOI lens. I currently have 3 Digipowers, 2 used with Gopro 11's and one used with an old 5. The GP5 at 2.7K@50p shoots for almost 6 hours. I also swapped GP 11's and the defect follows the lens. Then I have other Gopro 8's that I use for short sessions with their standard battery that lasts about 50 minutes in freezing water.
  22. I found on the fly these two videos shot simultaneously by the two GoPro 11s about 50 cm apart shooting from different angles this rockfall. 50 cm depth set with flat color and WB 5500 K. The difference in color should not be surprising. Unfortunately, you only need to change camera angles by a few degrees and the brightness and clarity of the water changes from day to night. It depends on the type of sediment flowing in the river. But look at the difference in definition on the rocks and leaves of the aquatic plant. In the next few days if I can find some more meaningful shots. We have TB of footage and it is not easy.
  23. My use case is so peculiar and I have no idea who will find it useful, but I write this post anyway to demonstrate how a seemingly simple thing can become a conundrum. As I described in a previous post, to use the AOI lens with the Digipower battery pack I used a 52mm filter holder. The first session went wrong because we found condensation inside the GoPro's protective lens. When we checked it, we realised that the weight in the air of the lens was able to dislodge the gopro's protective lens and lift the small oring. All it took was a tiny drop of water and the heat generated by the GoPro did the rest. The whole thing holds on the protective lens of the GoPro so great care is taken even when screwing it in and placing it in the water with two hands. Despite the care taken and the fact that the GoPro's protective lens had no fogging or condensation, subsequent sessions still had blurry parts that began to appear after about an hour of shooting. The mystery deepened. Comparing the bayonet mount with my screw mount, I realised that in mine, the back of the wet lens and the back of the gopro's protective lens are practically attached while in the original bayonet one there are a few millimetres of space/water (in my Backscatter version there is space to slip in red slide filters). I thought that the two lenses with the temperature variations and tolerances would come into contact, eliminating the water gap and producing that strange blurring. Rummaging around, I found a 52 mm male/female adapter that can act as a spacer. I also drilled two small holes in the filter holder to make sure no air bubbles were left inside. I also partially covered the small holes with tape because I had noticed a small purple glare on some of the shots. In short, I lost count of the number of hours lost to get the whole thing working. Result? Despite all those arrangements, after an hour the image starts to degrade and blurs/blurs appear in various places. There is no condensation in the GoPro lens cover and the reason remains a mystery. Another major annoyance, the ability to attract various crap floating in the river current to the dome. We have tried various methods, dish soap and Rainox but no dice. Hence the decision to stop using it for this task. Meanwhile, the other Gopros grind out hours without any particular problems except for the mediocre quality of the footage. A GoPro 11/12 shooting at 4K@50p on the surface gets hot and shuts down after a few minutes. We are doing continuous shooting sessions of more than 4 hours. The temperature of the river is 9 degrees and when we retrieve them they are cold. One possible explanation perhaps the water gap in the filter holder heats up and creates this effect. Yet it seems strange because they are two aluminum rings with considerable heat exchange capacity. or maybe the water gets contaminated? The only regret is not being able to predict this earlier. It would not have been difficult to design and print a bayonet mount for the GoPro mounted on the Digipower but there are only a few days of shooting left now. I'm afraid it will remain a mystery!
