PM'ed you.

Maybe after the Alex's video they will choose to produce them again

Well from my limited emails with Nauticam, they were very insistent that the N85 4" inch port was incompatible with the Sony 50mm 2.8 macro lens, and proceeded to suggest their recommendations from their port chart.

On the Nauticam #36471 n100-n85, the Nauticam website shows it in stock, though Backscatter says its discontinued.

I tried ordering it directly from Nauticam who told me it was discontinued.

I managed to find two online stores who still have it in stock, and ordered from one, still waiting for it to get delivered. Then I'll try it with the #36137 4"dome port and see how well it works.

Finally catching up on Underwater Photography Show episodes and got to the one about curved ports for wider macro shots.

In the comments, @Alex_Mustard mentions using the Sony 50mm with the Nauticam 4" port and a custom 16mm port extension.

Unfortunately the one he mentions has been discontinued. There is a N85 version available which should still work with the 50mm macro, but Nauticam's N100 to N85 adapter (which would have been perfect as its 20mm) has also been discontinued.

Are there any other options other than going fully custom?

Are the main differences between this and the UM5.5 the presence of physical buttons and USB charging?

You can refer to this thread here. I don't think anyone has done a direct comparison of both lenses yet.

From INON UFL-GR140 ZD user manual (note the R) :

  Quote

Supports wide-angle shooting modes of action cameras and quality larger sensors. GoPro's 8:7 frame/aspect ratio shooting mode (available from HERO11 and newer), and Insta360 Ace Pro's widest FOV, [ActionView], can be used without vignetting.

From INON UFL-G140 ZD user manual:

  Quote

Shoot in 4:3 or 16:9 frame/aspect ratio (HERO11/12/13) Vignetting will occur in 8:7 or [HyperViewTM] mode which compresses clip in 16:9 aspect ratio by using the full 8:7 sensor. Note that the lens hood may be appeared in a clip if camera is moved aggressively even shooting in 4:3 or 16:9 frame/aspect ratio.

I suppose the lens is working in terms of it not vignetting... I just hoped the sharpness would be better.

In the jack video, however, you can see that the problem is the lens. or a combination of sensor size/aspect ratio and lens.

I have the impression that the lens manages to cover the entire 8:7 GoPro sensor but that it is not designed for this mode.

Did you say the GoPro is in wide? Did you use the GoPro stabilization? It can also introduce artifacts.

I don't know if these defects are also present in photo mode.

I don't remember which part of the sensor the GoPro uses for photos. @Maria Munn , who is a photographer, surely knows more about it.

Don't have my Gopro with my at the moment, I believe the 8:7 setting is the entire sensor, so its the widest available aspect ratio. I believe I had Hypersmooth on.

The GoPro should be taking 8:7 RAW photos too, I didn't take any photos with the GoPro this trip though.

p.s. that's the resident school of jacks at Blue Corner, right?

You're correct!

the Inon lens is a little different from the AOI/Backscatter models, if I'm not mistaken?

Yes they're different lenses... I might have to try the AOI lens now.

Another 8:7 video with the Inon lens, placed in a 16:9 timeline so the corners can be seen. Some of the warping could be due to the stabilization applied in DVR.

A bit disappointed with the corners when using the 8:7 aspect ratio. However, the labs firmware makes editing Gopro videos significantly more pliable.

GoPro 11, INON UFL-GR140 ZD, Labs firmware, 8:7 5.3k 30fps, 10-bit colour, GoPro LOG profile (WIDE + LOGB=400), NR01=0, Stabilised, colour graded + noise reduction in DVR

I think the sharpness still falls away in the corners, but it does let you get closer. Can provide RAW video files if anyone wants.

It "works" with the 28-60mm Sony lens, but vignettes as expected in the wider focal lengths.

How was your experience with the 16-25? Which 180mm dome are you using? The N100 180mm dome (#37129) or the N120 180mm dome (#18809)?

Does the MFO-1 work with the Sony 28-60mm?

There is no contradiction.  Let's put some fictional numbers on things.  Let's assign the Zeiss lens a sharpness of 3, the a6300 sensor a sharpness of 4, the 14mm GM a sharpness of 7 and the a7RV sensor a sharpness of 10.  Right now, I am using the Zeiss on the a6300, so I am at 3 since I am limited by the lens and can't take full advantage of the sensor.  If I upgrade lenses, either using the 14mm GM or buying something new, it can only get me to a 4 because I will hit the limit of my sensor.  If I upgrade housings, it takes me to a 7.

Practically in your situation, if you're not interested in full frame housings, is to get a better lens/port combo. Even upgrading to the A7RV sensor, not many lens/port combos can resolve to the complete 61MP, especially at the corners.

This is much better depth-of-field than I expected at F9 on full frame.  Can you post a crop of the left hand side, and further up, so I can see it better?  Do you have more images like this?

A7C2, 28-60mm w/ WWL-1B, 1/80s, f/8, ISO 100, no strobes, centre crop, corner drop and side crop

A7C2 (33 megapixels, 7008 x 4672), 28-60mm, WWL-1B, no strobes

1/160s, f/9, ISO 500

100% crop below. It probably is sharper than the RX100, but we're dealing with a bigger sensor, much more expensive wet lens.

Just a quick google search:

https://www.backscatter.com/reviews/post/Sony-a6500-Camera-Underwater-Test-and-Review

They suggest the Tokina 10-17mm with an adapter.

This Zeiss on the A7RV would not be sharper than using it on the a6300.  The limit is the lens, not the sensor.

I am increasingly disappointed with my camera (a6300) as it is only 24MP and even then, does not give a sharp image.

Don't these two sentences contradict each other then? I think everyone in the comments are replying to your initial assumption that your photos are not sharp because of the sensor, which I think my example can help disprove.

I agree that it may be a combination of your lens and dome combination, although just looking at the Nauticam port chart, it already is the "ideal" solution. Of course, there may be sharper options out there for wide angle, but unfortunately, I'm not too familiar with the APS-C options out there, so others may be more helpful.

I'm on the new M4 MBA without any issues.

Could it be memory usage? How much RAM do you have?

Completely unrelated to the topic, but that's a hell of an image.I've seen similar in Cocos (but darker water) and in the Solomons (but not with the shaped "funnel" - where was this taken?

 

Thanks, this was taken at Aguni Island, Okinawa.

RX100V (so a 1 inch sensor), Inon wide angle wet lens, Inon strobes

100% center crop to assess the sharpness.

The resolution is 3648x5472.

From another thread for reference.

Do you enjoy the CMC-1 with the 28-60? Great shots!

Planning a trip to Ishigaki Japan in April, but the budget airline I'm taking is notorious for their 7kg carry on limit. I'm looking to save weight by using a duffel instead, but was wondering what other options people are using especially regarding weight.

I can confirm the Backscatter nauticam trigger works well with my A7C2 with nauticam housing. The TTL also seems to work well on land with the HF1s. I do like the fact the nauticam trigger is designed without wires, making it feel more durable, although it may be less viable for alternative housings.
