  1. No no. He is using a GH5. I asked him if he made some test with plain cinelike-d to compare. I'll let you know Bye
  2. I bring to file this old thread.... I found these two GH5 videos shots 4K 400 Mbps (4:2:2 ALL-Intra a 10 bit). Picture profile V log L and Color Correction with Da Vinci Resolve 15 Studio In this you can see before/after:
  3. I can confirm that this printed model for 12-35mm simply doesn't work: https://www.thingiverse.com/thing:2827917 I missed two dives and lost my clips. Never again. Once I bought the original Nauticam version i understood that it's not a problem of material but the design is completely wrong. Your mileage may vary with other projects.
  4. Hi Tim, Several friends of mine were in Zanzibar for diving in the last few years and all of them basically agree with Robin. Even in the Mnemba atoll. Sorry about that
  5. Ah ok I'm pretty sure it wasn't enabled before. Thank you all
  6. Hi Tim, I filled nearly every field. I updated my avatar but I find no option to change the background of my profile like @tomstgeorge I'm envious
  7. Really nice work indeed! Out of curiosity, how I change my profile background image? (behind the avatar). Thanks
  8. Laurent Ballesta did it again From: https://www.blancpain-ocean-commitment.com/gombessa-v Presentation video: You can follow the expedition via a Youtube playlist with daily v-logs https://www.youtube.com/playlist?list=PLLhFvmAOWaj4vKtuOf5qttwjR31PCHtnL Bye
  9. Yes, a bathtub is what I need (40°C in Rome today)
  10. I tried several times to switch for a moment to manual focus and engaging focus peaking (I have FP on Fn2). I've never been able to see the dots. Tried with several settings and colors. From my experience, even on land, peaking works only in few specific condition. I've never used FP with other camera but IMHO GH4 peaking sucks! This is the shot I missed (rescaled to 1080p) https://www.youtube.com/watch?v=0J0fx6O9jtQ It's plenty of contrast for focus peaking. I think I was too close. Other shots not so close are tack sharp. This lens is amazing. Minimum focus distance for this lens is 25 cm (10"). I guess is measured at 12 mm not 35 mm. This evening I will try at home. I will try again next week. I hope to find it again with open polyps while eating...
  11. @Barmaglot Thanks informative post. While definitively the 12-35 is not a macro lens form what I re ad I should get batter corner and a slightly wider image. I used multipoint focus just one time several years ago ruinining all my clips. No thanks. I'm sure focus was locked. F8 iso 800. Maybe I was narked... Thanks
  12. Thanks Tim My bad I used the word "macro". Actually the 12-35mm is a light zoom (24-70 in 35mm). I was filming very close some small corals at 35mm end. Probably too close. I was deceived by the GH4 AF which immediately locked focus so I thought everything was ok. So now I wondering if minimum focus distance per lens specs is of any use underwater....
  13. Sorry guys, Never too late for... a stupid question Underwater, a lens minimum focusing distance will increase or decrease? Specific case: lumix 12-35mm behind Nauticam 6" dome port (its port according to Nauticam). Sunday I made several nearly macro shots at 35mm with the subject very near. The camera indicated me focus acquired (single area pointed exactly on subject, AE lock, green square). Even on the boat, on GH4 display, images seemed gorgeous but at home on my PC i realized they were completely off focus. (I ate the dome cover).
  14. Old versions of Nauticam 6" dome for M43 was rated 75 meters. Now is rated 100m apparently with no modification. Go figure!
  15. I would never put a light on the port. First: you will get a lot of backscatter. A small arm is compulsory to get decent results. Second: housing o-rings are designed to work under pressure to fit properly in their groove (even a minimum one). On the surface chances to dislodge o-rings from their groove are high. So I would never stress the port collar with the additional weight. Just my 2c
  16. I used my NA-GH2 NA-GH3 several times over 100 m. No problem at all. All Nauticam housing are guaranteed to 100 meter but it's better to test if buttons works. My buddy had to change button springs to his sony A6300 Nauticam housing.
  17. Yes of course. Just create a 4K@30p project and put your files on the timeline. Everything should play fine by default.
  18. I see no problem keeping the clamp straight. During a dive I torture my arms
  19. https://cdn.shopify.com/s/files/1/2305/1013/products/B46I9304_730x.jpg?v=1515014084 Do you mean that they follow the handle tilt?
  20. <quote> does anyone know why on earth the handles are tilted?? </quote> Ergonomy. The same reason because a pistol grip is tilted
  21. I see nothing wrong with these clips.To my taste I would add some contrast and saturation. Maybe he likes them in this way. I suppose BMCC 4K has color profiles (???). Who knows which one he used.
