For macro play with settings to remove that distortion and use 4K 

Its really difficult to get good stabilisation and focus without tripod in any action camera 

In my opinion, you need tripod for macro videos with any camera

One question -- is the general unshaprness/blurriness of the background (area 2+ meters in front of the camera) here caused by water clarity, or is it the AOI lens limiting the focus range of the Action 5 to a narrower area right in front of the camera with infinity out of focus?

I also observed with GoPro+AOI that the infinity and even subjects 3m away are out focus, which is actually not that bad.

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.

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.

Yes, the edges are worse than I expected.

In the video of the turtle, on the right you have the blue and it's not noticeable. You have the reef on the left and I was about to write to you that maybe it was too close and therefore out of focus. Actually, with these lenses you have a very reduced MFD (Minimum Focus Distance).

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.

P.S.

I have lots of clips shot during a recent trip to the Maldives with the GoPro 11 and the AOI lens, but with original firmware and in 16:9. If only I could at least find the time to download the clips... 😇

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

I recently shot something with the GoPro7 and AOI lens and really happy with the corners. I'd say the background starts losing focus about 5m in rather murky conditions in Okinawa: https://www.youtube.com/watch?v=7cXdJGjeMKw
But if I compare this to an vid without the lens, there's not much difference in this regard: https://youtu.be/OMFi4DTTuCA

(this is also in one of Palau's murkier sites, Grassland/Sandy Paradise)

However, corners/sharpness are really night and day with the lens.

Issue is this is not not a true comparison - despite being on the same camera with the same settings, the Palau clip was shot in 2.7K linear and the more recent one with the AOI lens is in 4K Wide (my old laptop cannot handle GoPro 4K's HEVC codecs, so I need to work in proxies in FCPX to edit - time consuming, so when I was working in diving I just shot in 2.7K to avoid the issue).

Regarding the fov, without the lens, I prefered linear to wide - the wide lens changed thant of course, as it both corrects the corners and improves the general forground sharpness, with a low MFD.

Anyway, this is really interesting. I really look forward to seeing some more GoPro11 + AOI footage, as well as other combinations, especially the DJI models.

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

You're correct!

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

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.

Yes, correct.

And the INON UFL-GR140 ZD you have is the updated lens to work with the new GoPros and it's made to work with the 8:7 aspect ratio 😒

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

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:

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 noticed that ZD is the new Inon mount for these lens and they sell a converter for the previous SD mount. Maybe they changed it to differentiate from other Brands that use the same mount 😈

On a lighter note, as I've already written, I believe that whoever names products in the tech industry is a sadist, and I imagine there's a circle of hell dedicated to them. It always brings to mind that hilarious bit from Woody Allen's "Deconstructing Harry" when he takes a little trip downstairs. The description of the circles of hell is delightful, as is the joke with the first damned soul.

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

@David DB So by using Inon ZD mount you could change the AOI UWL-03PRO mount and now it would fit on a it would fit the INON’s ZD adapter .

Hummm, do you mean the mount on rhe lens?

I don't think AOI and Inon mount have the same way to attach to the lens. IIRC, on my AOI UWL-03 the mount is attached to the lens via 6 small screw.

This is the adapter you were taking about and it comes with six screws.

Yes but I don‘t if screws and holes are compatible with the AOI lens. Impossibleto judge from the photos. I believe it's unlikely and it would be a great stroke of luck 😁
