D850 is when IQ peaked and it had already surpassed what’s usable, unless you shoot for lab tests, inmo. As @TimG I’m also a Nikon shooter DSLR since old. Downsizing was the big advantage for me when I went mirrorless. The electronic viewfinders on new mirrorless can be very good (not all) as well as the AF. So if you’re not bothered by size and weight (travel?) or buying 2:nd hand, there should be super deals on eg Nauticam or Subal 850 housings.

Hi Tino I've just have this printed in China (JLCPCB) but not sure how it works. On my print, the larger ring slips off the smaller retainer ring - did you glue it on? Or maybe I'm mounting it wrong / the material used. thanks!

I'm not 72 yet but I feel every kg these days, while it's certainly tempting to want to take your favourite camera UW, there's lighter options that are every bit as good these days. Not saying don't do it but check out the size and weight of a housed D850 and how you would travel with it before leaping in.

Is there anything you can’t do with your D850 that you think you might be able to do with, say, a Nikon Z? I doubt that focussing or underwater image quality will be significantly better with mirrorless. I’ve been a long-time D500 user (and like you D100, 200, 300 and 800) and hankered about going mirrorless. But the only real advantage I could think of was in-viewfinder review. A very nice feature, especially for macro, but at huge cost: new body, new housing. As Dave suggests, you can probably pick up a used D850 housing in great condition for an excellent price. Two have been advertised recently on our Marketplace.

The quality and focus abilities of the D850 are at least 90% as good as anything else on the market. Certainly the lenses are as well, often its the same lenses. There are clearly advantages to mirrorless models, which is why i upgraded to the Z8. However, i kept my D850 and housing as a backup. You would be very happy with that system and can get years of use out of it.

Honestly from what I've read the D850 can do still images with all but the newest mirrorless. Plus I'm betting you can find a housing for a decent price if you keep your eyes open. Many people are still using adapted lenses from that era.

I am a Nikon shooter from way back in Nikonos days. have gone through many Nikon DSLRs and housed D200 and D300 with aquatica housings and Ike 125's then 160s. Had a long hiatus as my veterinary practice grew too fast. Now I find myself wanting back in the water at 72 but still capable with my favorite DSLR ever the D850. I could make the jump to mirrorless but the D850 is so much more capable than anything I've used I say why not make my underwater last run with my favorite camera? Just need a used housing , I have all the rest. Or does it make sense to jump to mirrorless for the focus improvement. new housing and new camera. but also new lenses. would appreciate some opinions and wisdom. Thanks. Wally

Particulate greatly reduces how much light you can throw at the subject and the distance you can throw it from before all you are illuminating is the water.

I’d concur that CoCoView is a solid 3-4 star dive resort and I can’t wait to get back. They may have trouble accommodating 30-40 people, though.

Not Roatan but Utila. Whaleshark. Very elegant and enthusiastic free diver , a good friend. It's a bucket list dive. Special day. Wally AKA Tiger

I've been to Coco View many times and have great friends there for years. It's very relaxing diving and a very social way of doing things so you make good friends on the boat. I have wonderful memories - on one trip I was fortunate to be there the same week as Stan Waterman . Still diving and telling so many stories from the past. Any of you that don't know Stan's story its worth a read. He was a pioneer , film maker but most of all a storyteller. Sadly Stan passed away - he was a true renaissance man. Diving the West End while you're on Roatan is worth it. A little Bohemian village. It's worth a day off the resort property. I spent the day there at West End after I'd been doing a veterinary spay surgery clinic on that end of the island with a great group of people. After the vet clinic work , we went zip lining and just walked around . I got the very best grouper photo ever that I had canvas printed but sadly lost the file somehow. Wally aka Tiger

Greetings Alexey from the wonderful inspiring country of Ukraine. I am from North Carolina the home to many shipwrecks and sharks that patrol them . We get divers from all over the world anxious to be surrounded by sharks. Borrowed my handle from our friends the affable sand tigers that are like dogs. They appear out of the vis limit or out of the bait ball and hang out with us.

I have published the design for the updated Reduction Ring Set & Diffusers on MakerWorld: https://makerworld.com/en/models/3206771-retra-reduction-ring-set-with-diffusing-filters#profileId-3629441 I've dove them a few times and filters worked out very well. No issues in the water and they light looks great. The diffusers only lose about 1/2 stop of light. The yellow filter is very close to 4500k filters from Retra and Backscatter. This set is 100% printed, including the diffusers, which is an improvement on my earlier design that used non-printed parts for the filters. You can now make an entire set with just a few types of filament.

Thanks all who helped or "only" try to help... ;) If I found time tomorow I'll make a new topic with what I wanted to make at the begining. Good night, morning evening afternoon depending of your location.. Hugues

We already have a thread on this 😉 Until confirmed, please use the General Chat.

Is LOFIC The Future Of Action Cameras? I hope to see a M43 LOFIC camera one day!

If it’s true (like the rumors regarding the 100mm macro lens last time) maybe there will be a surprising feature, too. Maybe supports Sonys TCs! ;-) Looks like it’s close focusing because it is „slow“. From sonyalpharumors.com: https://www.sonyalpharumors.com/category/rumors/#google_vignette I have to be honest with you: one of the sources who shared accurate Sony FX5information told me that Sony has a host of new lenses that will be announced within a relatively short period. Now, HowToFly has shared the full list of engineering prototypes Sony is reportedly working on. It therefore appears that Sony could announce many new lenses within the next three to six months. HowToFly writes: I can add that also the 16-28mm f/2.0 GM development has been done and could be the next lens announced by Sony. Now let’s dig into possible aperture info of some of these lenses: The fisheye zoom will definitely be slow and have something like a f/5.6 aperture The 28mm G is going to be f/1.8 and a successor of this very old 28mm NON-G lens The 40mm G is also going ot be f/1.8 as we already do have a slower f/2.5 lens. So that’s all we know so far…with the 16-28mm f/2.0 probably coming in late summer or early fall and no new timeline for the other lenses yet. In the meantime let us all know:

I jumped directly on the underwater part. I didn't listen the guy. Are there special lens for underwater use to mount or the magic happens in the new hosuing? @RomiK does the X6 fit inside the Nauticam housing?

I would say i disagree with two of the sentiments: 1) Most of my images expose the background, so that is a normal use case not a unique one- even if a close up and definitly CFWA. I find ISO (aka light) to be the major compositional hurdle in much of my image making. Sure packages are great at removing noise - but they all still do it at the reduction of sharpness. Absolutely agree that in this sense a smaller sensor allows an easier to shoot fStop that allow more relative light to the sensor -but I will sacrafice corners and either crop or just live with it when I need to drop below f/13. Also a couple of stops provided by wet optics also brings things closer - but $$ and size. 2) I have never wanted less than "more" dynamic range. I can never have enough especially when trying to get the darks to come alive to balance bright foreground subjects. I think there are very strong arguments for M43/aps-c/ and FF. All can capture amazing images - no doubt. But I think we are a group that constantly pushes the abilities of even modern sensors to their limit - even though we often (if not pretty much always) are adding light with strobes/lights.

nono, there are stitches alright, just invisible. In 3:17 he holds cam on invisible stick in his left hand. So the stitches go right across the frame. They did really good job with this second gen of housing. Still very much different optically from Nauticam case as you can also see from my pool test. Nauticam top x6 bottom. This from 20cm.

Ok great.... The attach bar is fetched when you click a blank reply, then inserted. That insert has a bug. For almost everyone it still works. Your browser session was the only one we saw that got an extra script in that fetch, so the bug skipped the “Drag files here…” block. Something on your side is making the software send that extra script. The best fit is your browser language set to French while the account is English, or an extension / VPN changing headers or cookies. The work around I put on the site seems to be workin.... I have reported the bug to Invision. If a blank reply ever loses the attach area again, tell me.

I stayed with APS-C for practical and financial reasons. I had a Sony A6000 with a Seafrogs housing that was a kind of universal, and when I upgraded to A6400 it was still fitting to the old housing. This setup I mainly used for videos. Later I upgraded the housing to a more ergonomic Nauticam housing (used one). I'm quite happy with the video quality and the ergonomics of the housing. I considered only once to switch to full frame. I had a project to film in a lake during night. Switching to FF Sony and finding a proper wide angle rectilinear lens with the fitting dome port in a Nauticam housing would have been a serious investment (probably over 10K Euro). Finally I just bought a 11 mm 1.8 lens to replace the F4 10-18mm lens for this project. As I remember it was below 500 Euro. I'm quite happy with the results. Would a FF camera produce better material? Probably. But not by a great margin and certainly not 20X better. Fast lenses are relatively cheap for APS-C cameras and they can solve issues with low light filming.
