One would think the story is clear but it is not :-) In short glass is glass and these are two different tools for different jobs. I am on my way to Maldives to see what the X6 is going to be about and on the meantime I am posting two lab shots. One at couple centimeters from the pad and one at like 60cm. This may not be the whole story as after Maldives I will have ocean samples from X5 in Pro and Nauticam cases and X6 in Pro case. And then we will see.

I have now captured the failure on your account twice, automatically, without you needing DevTools. Once on this topic at 17:04, and once in a private message at 19:39. Same result both times. Invision does have a client-side debug path, but it is switched off in the version they ship. When the attachment area fails to appear, the software calls Debug.error() — and in production that call goes nowhere. Debug starts disabled, nothing ever turns it on, and no adapter is registered to write those messages anywhere. The failure never reaches the server logs, which is why there was nothing useful to look at on our side. So I added a small diagnostic of our own. It watches the reply box expand, records whether the attachment request happened, what came back, and whether the "Drag files here..." bar actually appeared in the page. That is how we caught your two failures today. It does not collect the text of unsent messages — only whether the attachment UI loaded. The request that fetches the attachment area does reach the server, and the server answers 200 OK with a full response. The upload library also loads. After that, the bar never appears in the page. It isn't hidden, and it isn't being removed by an extension — it simply never gets inserted. New topics, post edits, and any reply box that already has text in it ship the attachment area with the page. A blank reply box (forum or messenger) fetches it afterwards. Only that second path is failing for you. Your account is not the problem. Two other members on Windows 11 with Chromium 151 also work. Zoom, High Contrast, and storage are all fine on the sessions we captured. Object.assign ERROR You were right to flag that, and the analysis you posted got the structure genuinely right — new topics load the editor in full, replies fetch part of it separately. That matches the source code exactly. The error itself turned out to be a dead end. I get that identical "Cannot convert undefined or null to object" message on my own machine, in a session where uploading works perfectly. It is a harmless ordering bug in the notification code, unrelated to attachments. Real, and worth chasing, and I did chase it. It just didn't lead anywhere. Could you try once more, on this topic, the same way it usually fails — click into the empty reply box and wait a few seconds. If the attachment area still doesn't appear, you don't need to paste anything from DevTools. A short "still missing" here is enough; we will already have the diagnostic. If you have a moment, a second try in a private message (empty reply box again) would be useful too. That is the other place we saw it fail. thanks...

Marelux lists the RF 20-50mm PZ on the Aquista 135D lens chart with a zoom gear (#51211) and an extension 30, so zoom range from 28mm to 50mm. I don't see the lens on the port chart yet but my guess is that the extension 30 with a 180mm dome port would be a good starting point. As a side bar, Marelux has also added the new RF 7-14mm fisheye zoom with zoom gear #51210 and extension ring 30 with the 140mm dome port with bayonet dome shade.

Welcome. I am selling a Nikon D7200, Ikelite Fourlock housing and assorted Nikon lenses if you want to purchase something to get started. Let me know. Dave

It just depends on what you shoot. For macro, I agree that high dynamic range is often not needed. But I’m primarily a shallow water wide angle shooter, and the background in those shots is natural light, where high dynamic range can make all the difference between a shot working or not. The real noise/image quality differences are greater than shown on the DXO graphs. To make a fair comparison, images need to be normalized to the same resolution. However, DXO downsizes the images to 8mp, which is very inadequate for photographers licensing their photos, making large prints, entering big contests, etc. For people like myself who want to make full use of the 60mp of the Sony A7RV, the useful comparison would be enlarging the Olympus files to 60mp for the comparison (or at least normalize both to a decent resolution in the 30-50mp range). With my FF setup, I do not have to stop down more or use a higher ISO than MFT. My wide angle can give sharp edges at f/2.8. Though if I am using optics that require stopping down more, my preference is to increase strobe power and exposure length rather than increasing ISO. Either way, I’m rarely shooting at higher ISO than I would be on MFT. Anyway, there is no one best sensor size. It varies according to the priorities of the individual. For many photographers, MFT provides adequate image quality for how they use their photos, so the size/cost advantages make it their best choice. But for other photographers, maximizing image quality/resolution is the priority, so FF is the best choice.

@RichN I know you are and other volonteer I appreciate the work you all have done That's not the problem ;) On the other side all the member writing reviews, share some DIY etc... are also volonteer we participate to the life of the site, putting some intersting stuff on it. It's like for you time we "invest" to make the site living Thanks for try to solve "my" problem.

Cut&Paste + Drag&drop it doesn't work.. it's the same probleme. If the banner appear I can paste if it's not I Ican't paste. Why I use Paste : Easy, I use Greenshot and when I select a region I configure Greeshot to put it in the clipboard... It's fast and that's a important point for me.

Aloha and welcome Alexey! Just a thought: full frame camera and lenses are great, but if you’re planning to travel, you might consider smaller sensor cameras as the lenses (and ports) are oftentimes much smaller. Unless you really need the large file sizes, you might find that APS-c or M43 will suit your needs. More to think about, yes, but we are here to help you spend your money. Best, Craig

it doesn't work. Flash is completely disabled with electronic shutter: https://eww.pavc.panasonic.co.jp/dscoi/DC-GH7/html/DC-GH7_DVQP3109_eng/0058.html And here: https://eww.pavc.panasonic.co.jp/dscoi/DC-GH7/html/DC-GH7_DVQP3109_eng/0168.html#00007 The flash does not fire when using the following functions: – Video recording – [ELEC.]/[Silent Mode] – High Resolution mode – [Filter Settings] The documentation clearly states that the flash will not fire when the shutter type is set to Electronic, or when Silent Mode (which forces the use of the electronic shutter) is turned on. This is a standard firmware block implemented by Panasonic across their camera bodies with non-stacked sensors. It is designed to prevent users from capturing partially illuminated frames, which happens because the electronic readout speed of the sensor cannot synchronize with the brief duration of a strobe flash.

Yes, I simplified a lot. You brighten the background by changing the ISO, basically exposing for the ambient light. But here Chris post comes into play: to get decent corners in full frame you have to work with approximately two stops narrower aperture, and so from the chart he posted you can see that the SNR is practically identical. In short, technically I do not see all this difference. Then for large prints I agree. But I still think that this endless debate comes down to corner cases. Camera manufacturers develop and market the full frame format to meet purely terrestrial needs, such as the search for a shallow depth of field for portraits or clean images at very high ISO for reportage. None of these features is optimized for shooting through a glass lens submerged in a liquid. Underwater optical physics, if isolated from the global market, would benefit more from the balance offered by smaller sensors. Micro four thirds allows the use of hydrodynamic domes and guarantees a native depth of field that greatly helps composition while diving.

HI Nauticam lists compatibility with Port 41 in its chart, without mentioning any restrictions. Could it really be used at 20mm with a flat port?

I have a GH7, but since I shoot video I have no idea. If you tell me how to check, I can see if I can find out for you. That said, I only have a cheap flash that I bought for topside work, and I don't really know what it is capable of. If you want to send me a direct message, we can talk further.

Hi Alexey! A warm welcome to Waterpixels - especially coming from Ukraine. Great to have you with us. We hope lys really enjoy the forum. Best wishes Tim

Very nice, thank you

What you describe is exactly the situation for many macro photos... In many WA photos, however, shutter speed, aperture and ISO are adjusted to give enough ambient light for the background, otherwise the photo may look as beeing from a nightdive (when everything is mostly lit by the flash(es)). Flashe(es) are normally only able to light the foreground object(s)... When a little deeper, even in very clear waters and sunshine (not to speak about our lakes)), the camera settings come soon to their borders to give a pleasant background (motion blurr, corner sharpness, noise and sometimes even dynamic range)...

I am not an IT person or anything, but I am trying to figure out why you are insisting on "cut and paste" instead of "drag and drop"? I always drag and drop any photos or videos and have no problems at all (unless they are too large).

Hi everyone! My name is Alexey, and I'm a diver from Ukraine. I'm passionate about underwater photography and was looking for a place where photographers could share experiences. That's basically why I'm here :) My main setup: Olympus TG6 + Kraken KRL02 wide wet, 2xInon Z330 or Backscatter MF1 & Snoot. I love both: macro and big ones, but really enjoy diving with big sharks and mantas. Experience: certified in late 2020, now Rescue with 500+ dives. Diving in Ukraine, Egypt, Mexico (both Baja and the Caribbean), Panama, Kenya, and the Maldives. Planning my upgrade to Nauticam + something like Sony A7V, but scared of the weight and the price of all that stuff :)))

I'm on the NW coast of Tassie. Airfares and accom are booked for the Go Diving show, I will have the Monday morning free to visit camera stores. I think that is just Underwater saying that they will have OM System gear on their stand - not 100% sure though. Nikon have a stand also, not sure about any others. Are you going?

Locally it is probably more to do with the loss of big industries that were the major employers - paper mill had 3,300 workers, a local company made such incredibly good underground mining equipment that Caterpillar bought them and then a couple of years later moved the plant to Thailand - 600 jobs gone, paint pigment plant closed - 250 jobs gone, and so there just wasn't the money in town any more to support things like a camera shop.
