  1. Panasonic achieved a result that Apple, Sony and Nikon did not. The Japanese Intellectual Property High Court invalidated a major RED patent concerning raw video files. RED had historically used this patent to demand licensing fees and stop competitors. Nikon initially challenged the patent in court but purchased RED before a ruling and dropped the case. When Panasonic recently challenged the same patent in Japan, Nikon defended the claims it had previously opposed. The court ultimately rejected the patent and ruled it invalid.

  2. So M43 is still the most compact. A 12-35mm requires a 6"/150mm dome for stellar results. Even a 8-18mm requires a 180mm dome while in FF a 230mm is required for best results.
  3. Which lens did you use? Ciao
  4. I am posting it here because at the moment it is only a rumor. A piece of news however that if confirmed would make many underwater photographers happy. The source on X is considered very very reliable. There are no dates. We will see.
  5. Sorry, no. On WWL you would use a 14-42mm. I'm not expert about other wet lens. An Oly 9-18mm (not very good) or a Pana 8-18mm are wide already (16-35mm) and they use a 180mm dome.
  6. Yes, @Architeuthis post explained it vwery well. it depends.
  7. I have a back-button focus even on my coffe machine BTW

  9. I use the 45mm for video. Qualitys stellar but the AF is really slow even on normal shots on land. The 30mm is way better even if it reaches its max magnification on glass. IIIRC it uses the same port of the 45mm.
  10. Hi Monika, Welcome onboard! Ciao
  11. @Adventurer could you show us which kind of photos are you getting with your system? I'm very curious about this Ivanoff system
  12. Actually this is the first camera without insane RAW data rates. Raw data rate is comparable with the compressed H.264 and 265. Other raw flavors (Red and Prores) are around 1Gbps. Hence it's the first time that a raw is a viable option for some problematic shoots without taking a mortgage for media cards. Sony FX5 Codec & Data Rate Breakdown X-OCN LT (16-bit RAW): ~389 Mbps (at 24 fps) — highest quality raw option available internally on the FX5. X-OCN C1 (16-bit RAW): ~289 Mbps (at 24 fps) — balanced intermediate raw compression. X-OCN C2 (16-bit RAW): ~232 Mbps (at 24 fps) — maximum raw compression tier designed for smaller files. XAVC-I (All-I H.264): ~384 Mbps (4K 24p equivalent) — traditional heavy intra-frame codec. XAVC HS (H.265 Long-GOP): Varies down to lower distribution bitrates (typically 100–200 Mbps range depending on user settings) — significantly smaller footprint for non-RAW delivery.
  13. Custom WB could be a problem shooting in H.265/264 but in internal 16-bit linear X-OCN RAW video allows you to change and fine-tune white balance non-destructively in post without losing image quality.
  14. Basically the only advantage of these lens is the reduced minimum focus but the WA lenses (Inon 165 and AOI UWL-03 become useless for infinity focus). If there is a good subject within the focus range (the jellyfish in the Nando's video) the blur/OOF effect could be nice but if your main subject is out of the focus range or you are simply panning and truck on the reef the effect is catastrophic. Guys, your tests are valuable and interesting. Please keep posting but we try our best to keep the forum slick and clean so that our member can find easily the content they are looking for. @BeppePADI please do not create a new topic for every new post. I'm continuously merging topics. We have this topic for all with and without wet lenses comparison. @Nando Diver I moved your latest posts here: that thread was about GoPro Lab fw and not wet lenses. Go Dive! 🤿
  15. basically the AOI lens behaves like the Inon. In your video the out of focus effect is much less visible due to the bad viz while in the @BeppePADI video here it's clear thank to the better viz.
  16. In the last iterations, no. All new monitors are 1000+ NITS and they have sunshades.
  17. Which model is it? A friend of mine bought two of latest hi-power Sea Frogs. Everything ok so far but we will see in the long run. I've seen the more expensive Weefine equivalent and the mechanical quality is gorgeous as my monitor but I didn't have the chance to test their light underwater.
  18. Don't you have a clip at infinity focus?
  19. Lens has been officially announced in China: https://www.7artisans.com/prod_view.aspx?nid=3&typeid=125&id=576

  21. It seems to me that the Inon lens (and I imagine its AOI cousin as well) literally sucks. IMHO unusable for wide shots. On the other hand, the GoPro without an additional lens does a great job. Did you have dive mode in the last clip too? In these dives a URPro filter or even a Keldan gel would work miracles in post. Interesting that the turtle searches for Cymodocea leaves among the cursed Caulerpa
  22. I came across an incredible video made by the NASA one year ago. It's one of most detailed visualizations ever created of Earth’s ocean currents. NASA’s ECCO model pulls data from spacecraft, buoys, and other measurements. The map reveals massive rivers of moving water, swirling eddies hundreds of miles wide, The Kuroshio Stream and the powerful Gulf Stream carrying warm water from the Gulf of Mexico across the Atlantic. P.S. And yes, after seeing it, we all thought the same thing 😉
