Aloha and welcome @Francy1505

It does work just the same as it did on my old nauticam housing. I'm currently using the OLY E-M10 Mk IV backscatter octo housing (FLP-06 PEN Flat Port) with the Nauticam M67 Port to Bayonet Mount Converter II to mount my WWL-C and CMCs.

ill take a look later today..

I consulted with the official personnel of Nautiam, and they said that the basis for determining the appropriate length of the extension ring is that the front mirror group and the ball cover surface are parallel. They have given more consideration to the situation of 7mm Based on my measurements, the flange difference between Marelux-rf and Nauticum-rf is 7mm, which means that if Nauticum has a length of 20mm, Marelux needs 27mm

Those were the times of the legendary cracked GH2. Like a tuned scooter. I never investigated the Panasonic custom modes C1, C2 , C3, C4 I think tou can have different AF types but not fixed focus points. regarding my sad story, today it is impossible not to notice it. Focus peaking for video and for photos the various AF modes show you exactly what it focused on.

I followed your advice and conducted tests on land using 3D printed extension rings (30mm and 35mm). It can be confirmed that the 35mm extension ring in the 14mm focal length can only see slight dark corners when the camera anti shake group is working, while there are no visible corners in the 30mm range. Checking the image quality, it was found that there was almost no difference between the two under F10 F13. Therefore, 30mm is the optimal extension ring for RF7-14

I know that on a french forum with the same framework.. I reached a global limit. The administator give me more space to solve the issue If @RichN can check this point ...

It's strange because we have a limit of 10 photos per post. Maybe @RichN can check it.

Ah yes 🙈 sometimes my mind races ahead of fingers 🤣

I try it from an other PC.... it doesn't work.. I guess I reached my upload limit. @Davide DB Can you check please Thanks

Interesting experience, thanks for sharing (and not re-iterating the curses). It would be nice to be able to program two focus positions into the camera, say on an Fn button or so, for a given lens. Then we could have it all- fix-focus for reef and CFWA plus AF if we want to. And the ability to switch rapidly and reliably between all this. Does that exist?

Thank. I am very happy to be a part of this amazing community.

Hi everyone, I am looking for a 3D printable file (.STL) for a Nauticam zoom gear for the Canon EF 8-15mm f/4L Fisheye USM lens. I am using it inside a Nauticam NA R6 housing with an EF-RF adapter and a Saga 4" Minidome. Does anyone happen to have a tested file or a parametric design they could share? Thank you so much for your help!

Welcome aboard Francesco! Ciao

Hi everyone! My name is Francesco and I am just starting out with underwater photography. I am shooting with a Canon R6 in a Nauticam housing. Thank you so much to anyone who can help me learn the ropes! Best regards, Francesco

There is a problem. It's impossible to post some other pictures. I already reboot my PC...

A drop in the ocean but definitely a good news

I am sorry I sold that lens and the minidome several years ago. The quality was great, but for video it was really not very usable except few cases. I still remember its MFD and ability to focus on the dome and even inside it. Once I went for a dive in a mountain lake with 40 meters of visibility. From the bottom I had filmed all the houses in the village and the trees. AMAZING!!! I went back home all excited, only to find out that the camera had focused always and only on a tiny speck of dust on the inner surface of the dome. Mountain legends say that on foggy nights the curses of a stranger can still be heard echoing in the valleys. P.S. No, I did not notice it on the small display given the huge depth of field of the FE and at that time I still missed the wonders of focus peaking.

Hi After some trouble with my setup, I need to changed my FO... I decided to use some of the fiber I bought at the group purchase @TimG organize some times ago. I already had a 3D printed I build... but I wanted to have a more versatile version. That's the reason I build a new version. This have 3 variant one for 2 mm fiber, one for a 3 mm fiber and the last for 2 2mm fiber. The result is

I think there’s two aspects to this - using a very specific lens that’s off the charts and then the « tinkering » , i.e. how to actually fit it in a system. Tinkering is a fun project for some «dry » evenings /weekends but ultimately only rewarding if the photography gains something from it. I adapted a manual fisheye for a simple m43 system and that was fun (you can find a post somewhere on this site). For dome-ports, a simple way to verify a reasonably correct position is to take a split shot and look at whether off-center vertical lines match between above and below. There are also some reports on this on the forum, @DreiFish has included this in his testing-routine which I think is as good as it gets. The MF fisheye exercise is image -wise of course nonsense for m43 because the AF lenses exist and are even quite affordable. For me, it was a test to see whether I like shooting a FE (which I bought for above-water use) under water. Fisheyes can be used fix-focus as @Phil Rudin described and I got some good shots with my setup. I can change focus for CFWA but that is difficult to verify under water. Keeper-rate is so-so. Rectilinear wide lenses have a shallower depth of field than FE and are more sensitive to the curved virtual image - that does not make focusing easier. And I think doing macro with an MF lens will be very challenging. Yes, one may anyways choose to pre-focus an AF lens and then use focus-peaking to pull the trigger. But having at least the option of AF will make you more flexible and faster for unexpected opportunities. What’s better, a sharp frame that you need to crop or the ideal focal length and framing but slightly out-of-focus? AF may not be what I miss most on my FE, but changing the aperture is important for sunball shots and those are a staple for FE. I am looking out for a second-hand Panny 8mm on the classifieds, that’s the bottom line.

That weird perspective could work well in some situations - and be a downright pain in others!

Another good news story from the south Pacific. "Samoa’s Marine Spatial Plan provides a national framework for the sustainable management of 100 per cent of the country’s ocean. The plan expands national marine protections through nine offshore marine protected areas and a formalised network of coastal community marine protected areas. Together, the areas protect 30 per cent of Samoa’s ocean, approximately 36,000 square kilometres." Samoa puts ocean protection plan into action

That is a big lump of glass, 90mm diameter. 580 gr and $AUD2800 in round numbers. Keep in mind that very wide rectilinears produce weird perspective effects with the foreground objects looming very large.

I understood that you were talking about the housings and not the cameras only from the prices 😇
