  1. No, totally accurate at the time of writing. Quoting numbers from mid May on a post of early March is a bit off-track maybe? Anyway, still all in good shape here. At the end of the year all you might notice is a rounding difference in mortality statistic. Situation is of course different elsewhere. Interestingly enough the numbers are worst mostly in countries with bad / failing governments.
  2. I have hot played with most of those cams, but if AF is important to you, forget about the Blackmagic 4k/6k and the Z Cam. All I hear is their AF is bad overland, so it certainly wont get better underwater. The concept of the Z2 as a kind of „Mini-Red“ is certainly quite interesting nonetheless. Housings for Camcorders are scarse. For Z90 you get a housing from Gates. Depending on the cam, have a look at Seacam housings. They are superb. Whatever you take, get a decent set of UW lights. Keldan is the gold standard. I use the Keldan 4X. Compact and powerful. Particulary for macro, you cant do without.
  3. Sometimes I get the impression this virus has more impact on the brain than on the lungs. Getting bizarre. Here in Germany we had 25.000 peoples dying from the flue in 2018 alone. Zero so far on Corona. And people stack loopaper for the next 10 years... Lets have a Mexican beer, shall we?
  4. 95% of it, yes. The humpbacks even from a bumpy zodiac ;-) Only the timelapses and some of the close shots of the penguin chicks getting fed are on a little travel tripod. I was never able to achieve that type of free-hand stability on a GH5 (or any other classic photo cam), be it underwater or overland.
  5. Have a browse thru some YT reviews, but basically the Z90 has a removable top handle with professional audio features, it has an SDI connection for monitoring in addition to HDMI and a slightly more robust codec. But all other specs are identical. Yep, it sure will be good for Safari and similar trips. Here a link of some stuff I filmed on the Z90 on a trip to Antarctica last January. I got a pile of underwater stuff (Maldives) we the Z90 in the vaults - one day l‘ll get that out as well....
  6. Having used a GH5, a GH5s, a Sony AX100 and a Sony Z90 (the "pro" equivalent of the AX700) underwater and being a video guy only, the setup that works best for me is a dedicated video cam, currently the Z90. I am saying "for me" because what you choose wil depend on a lot of different factors. As you say, if you want to do phots as well as Video, you'd have ot go the hybrid route. Yes, the AX700 can shoot photos, but nothing to take really serious. If you are a video guy and - like me - hate fiddling with lots of different lenses, ports, extension rings, focus and zoom gears (just to find out when you arrive at the other end of the world that you left important bits at home...), then go for a Gates/AX700 setup. I just grab my housing before the dive and put it back on the deck after the dive and relax while my hybrid buddies are still spending another 30min+ configuring their rig for the next dive. Can be fun as well - but its just not for me. One battery takes you easily thru 3 dives. Whatever you choose, with both setups (GH5 or AX700) you cant go completely wrong as both are great systems. Just to mention: Yep, the specs in the GH5 look much more impressive. But you cant beat the super precise auto-focus on the AX700/Z90. The autofocus on the GH5 even after a quazillion of firmware updates remains to be a bit of a joke. And also just to mention: If you a are "big sensor" freak: Forget both both GH5 and AX700 and go for a RED Monstro :-)) Joking aside, its a topic somewhat blown out of proportion IMHO. The 1'' Sensor in the Sony does a great job! Good luck!
  7. Done that one. Its very nice indeed. Have you been in Fakarava as well?
  8. The housing is superb, particulary in conjunction with the Gates Wide Angle port. You get sharp pictures form edge to edge. It is completely neutrally buoyant if you use it by itself. Helps tremendously to achieve stable footage. Onthe right side, the manual white balance button is right next to the record trigger and the zoom trigger. You do your white balance and press shot. Takes just a second. There is a custom button that you can configure yourself. On the left you have buttons and a control wheel for your IRIS, ISO, Shutter, Focus. The autofocus is great, btw. What you cannot do is going deep into the camera menus to change settings. but I dont really need that. On land, you can use the sony remote to change settigns without openng the housing between dives. The battery gets you through 3 dives easily. Add a Saga flip adapter with a wet diopter and you are all set from pygmy seahores to whalesharks with one setup. No fiddling with lenses, ports, extension rings, gears and whatever else....
  9. Yes, Juan has put out quite a bit on the Z90. I am not entirely on his line re. the settings on this camera. I still very much prefer richer colors of the the CINE profiles over HLG - unless you're in very shallow water. HLG is in my view not suitable for underwater filming due to the lack of grading/ color correction headroom. Sorry, a bit off topic on a Nikon Z6 thread...
  10. Not yet. Was a bit busy with all sorts of projects. I'll get something out. Cant promise when---
  11. Triton Bay. Many whale sharks and you even get pods of dolphins from time to time. Canderwasih markets itself as whale shark destination but its a tricky area. Some liveaboards dont even go there anymore as locals can get both greedy and hostile.
  12. I could not agree more with this. I had a Sony AX100 in a Gates housing years back. Then I changed to Panasonic GH5 setup. Never warmed up to it. Now I am back to Sony camcorder, this time the Z90 in a Gates housing - and I‘m a happy fellow again :-)
  13. I am selling a ready-to-shoot Nauticam Macro-Setup for MFT-Systems. The Macro Zoom port and gear is in very good condition, as is the Olympus 12-50mm EZ Macro Zoom lens, which is included in this package with the Gear readily installed. This setup new is 850 EUR for the port/gear plus appr. 250 for the lens. I am asking for 650 EUR for both. Free shipping within the EU.
  14. Well, thats what the title of this thread says....
  15. Very nice. We did the Banda See crossing in 2016 and despite some very rough waters at times it was one of the best trips ever. I only got the hammerheads from the distance, so you were quite lucky! The water can be quite murky around Serua....
  16. Hi Val, thanks for your kind comment und spending so much time watching my videos :-) The Antartica video was pretty much straight from the camera just the usual minor tweaking of exposure, saturation etc.here and there. On some of the midnight sun clips I applied some noise reduction. Its actually not HDR/HLG as I did not trust my skills here. It is my well trusted and tested CINE profile in Rec.709. Not sure anymore whether CINE1 or CINE4 but they are pretty close anyway. I was also happy that I could operate the camera easily with the top handle and big gloves. Some of my photographers colleagues froze their fingers off on their cams... Burkhard
  17. Would be great if it would be that easy. Unfortunatly it isnt. I had done just that, invest in an expensive BM card, hook it to a TV etc. Here it start: No standard commercial TV is properly calibrated to really use it to judge proper HDR grading. What looks good/correct on that particular TV may look horrible if you play the final clip back on another TV. Its pure guesswork unless you invest in a proper HDR grading monitor. And these are still very expensive. Also the latest Macs are by far not HDR capable. They call it „extended color range“ which is a marketing gimmick for a bit wider range than 709. But its certainly not „proper“ HDR. And unless you use a RED or other big tool for your underwater filming, your HDR stuff is likely to look much worse than anything you can get in ole Rec.709 I have yet to see a HDR clip produced on a GH5, Sony HDR capable consumer camera or similar that convices me that these cams can produce good looking Rec2020 clips underwater.
  18. Hi Laval, my channel name is the same as the user-ID here, so when you search in youtube for it, you'll find it ;-) But I have only published some overland stuff (Antartica, Patagonia) shot on the Z90. I have quite a bit of underwater footage done on it in the Maldives - unfortunately I've not had the time to publish anything. Just played around here with grading to see whether its any good. And I am mostly very pleased with it. ON HLG, I disagreee with Juan - I had some exchange on this with him. I like a lot of stuff he's done but I am not convinced of his HLG stuff. HLG works absolutely fine overland. But as soon as you need the slightest corrections - and thats almost always the case for underwater stuff - the picture is falling apart very quickly. The codec is just too thin: Wider color gamut, 8 bits - good for WYSIWYG, not for grading. And HLG was actually never designed for grading in the first place. Even with the GH5, which does 10 bit, i have not been able to produce any really good looking output with HLG underwater. And I know of nobody else who has. Custom profile: I need to look them up and post separately. Nothing major. I remember I changed the Black levels and scaled down sharpness in 4k mode. I get back on that. Burkhard
  19. Nice. i was soing a couple of dives at Lord Howe a few years back. We didnt get sharks, though
  20. Very nice. I use a very similar setup these days, just using the Sony Z90 camera, which is almost identical to yours. I fully agree with your comments re. advantages of a dedicated video housing / camera. After I sold my Sony AX100 I used the GH5 and never really warmed up to it. Nice camera nonetheless. On ND Filters: I have used them underwater. When you are shallow on a sunny day, it can get very bright. Also on muck dives I sometimes by purpose use the lights on a higher level than needed and then put ND Step 1 on. This gives often a richer color spectrum. On color profiles: I use my own profiles based on the Cine1/Cine4 Profiles. Other profiles work as well. Just NEVER use HLG underwater. Looks pretty ugly. But I do use it overland.
