Hi There
GoPro 10 user here, upgrading to Osmo Action 5 PRO
My current setup is gopro10 + underwater case gopro + Inon SD front mask + inon light adapter + UWL-03 lens + Divevolk SL50 dive light.
What happen to AWB when the Sensor of OA5 PRO is blocked by the UWL-03 lens ??
What kind of issues can be found while using Wide angle lens with OA5 pro ? vignette ?
color temperature sensor of Osmo Action 5 Pro is built into the letter "O" of the logo on the front of the camera. Do not cover it during use. With the color temperature sensor, Osmo Action 5 Pro delivers outstanding color temperature performance even in scenarios with complex lighting, such as diving. The sensor corrects color temperature when filming underwater and reduces color temperature flicker due to the change of shooting angle. It can also detect and reduce light flickering more accurately. Update 2: does the quick release system will block the temperature sensor ?
Update
T-housing makes a expensive aluminium for DJI OSMO 4/5 and apparently will not block the sensor, the sensor might get light through the lens (not confirmed)

Useful information, not a diving user but thanks for sharing for those who are.
Osmo Action cams have already a realy wide angle of view. I wouldn't put any more wide-angle lenses in front of it. I use the Osmo Actions without any lenses while diving and with good visibility I also get very good results

its your opinion, but wide wet lens are much more than just wide angles.
The 155 degree FOV is much reduced underwater to about 90 degrees FOV, using wet lens will restore the FOV to 140 degrees.
The objects will look closer, lens will absorb more light , better colors and contrast, less distortion and accurate white balance.
My UWL-03 are the reason i dont feel the gopro 10 outdated...
here another video comparing images with wet lens and without lens on DJI osmo 4
Hi Nnado Diver
if the color temperature sensor is blocked, the Action5pro awb alogrithm will only consider the image from footage, no more consider the light spectrum.
You may check more reference videos or just ask AOI guys of their test result. (They already tested that.)
(My personal experience is it works fine, however I do not take it on the oceans ,just lakes)
the UW fov is not really pratical underwaters, you can just make standstill pictures that will be distored. When using video, you have to stick to standard fov otherwise all motions are very annoying to watch. So I'm not for an UW lens.
About the color temperature sensor, I am using it only for freediving, because once you go deeper, you have to correct it manually.

Over the last years, ive seen people upgrading to the lastest gopro 9, 10, 11, 12, 13 and Osmo 3, 4 and now 5, and continuaslly making washed underwater videos that they will never see again.
Some time ago Ive decided to stick with gopro 10 and spend 200€ on wet lens insted of upgrading to the lastest action camera model, best decision ever......because now im using all the potencial of the camera.
There are two benefits to that result from using a wide-angle wet lens. First, the wide field of view allows you to get close to your subject while still seeing the full scene (think of a shipwreck, whale, or reefscape). This not only emphasizes the subject / focal area in the composition, but minimizes the water between camera and subject. As a result, the image will be crisper and clearer, delivering better color.
The second benefit is that your strobes or constant light have greater power when closer to your subject. Light falls off dramatically underwater, so the closer your light source to the subject, the less water the light must travel through, and less degradation of the light. This also delivers better color, contrast, and definition in your images. And since you’re close, you have more room for creative strobe positioning to create the perfect lighting effect.
You can see on the second video (the OA4) that near the 1/5 left or right part of the image, the distortion happens. It's not a problem while filming on big centered subject as this very cool turtle. But had you done the same serie as the gopro video, you would certainly notice that. I have tens of rushes in 4K on my OA4 that cannot really be made good without a heavy rework.
Of course it can (and actually must) be mitigated by good manner of shooting your video.

Sure, it's because of the wide angle. But don't you have the same distortion with the additional lens, just more pronounced if you are going to close to the object?
The distance between the cam and the turtle was round about 1-2 meters on the OA4 video.

What I see in the video above all is that he had damn good visibility and lighting conditions.
THAT makes the biggest difference.
See some of my videos, with gopro 10 (8bit) + UWL-03, the lens made a huge improvment , depth is betwwen 15m to 25m sesimbra reefs (5-10m visibilty ) and other videos depth is +30m in Porto Santo/Madeira (40m visibility) The video description mention if lens are used or not..
To film underwater in deep or shallow waters using any action camera, the lens are a massive upgrade in the video, its like VHS to Digital.
Here 3 x non color graded video filmed gopro 10 4K 60fps + lens uwl-03 + one SL50 divevolk (CRI 96) dive light at minimal settings 1250 lumens
The squid videos are 22m depth...the Lens allow to be close to the subject and this means less water for the light to travel to iluminate the subject...No way the squid color could be achived withou the lens.
The Ruivo video is about 10m depth lots of natural light (about 11.00am) and here also the lens help to capture are the details.

Thanks, i will take a look.
You have some amazing videos on insta (and a new follower :-) ) .

I have watched your videos. Yes, they do look interesting.
However, I'm not quite sure whether most of the advantage isn't just the shorter focus distance than the GoPro or Osmo Action normally have.
With the Osmo Action, however, this can be adjusted very quickly without additional lenses.
Whether the distortion disappears at the edge is not so easy to tell from your videos.
One noticeable thing about the underwater footage from the DJI Osmo Action 4 for snorkeling is that if you use the 16:9 aspect ratio, and leave it in the Standard (Dewarp) field of view, everywhere but right in the center of the frame is very soft (not sharp) and the subjects appear very warped when close to the edges of the frame, which sort of defeats the purpose of a 4K camera.
Combine that with a short focal distance, and fish coming in close from the sides are really not sharp. In the screenshot below, you can see how soft and warped the feeding corals look around the sides, and they are only sharp in a small central area. Fortunately there is a solution to this issue.
Make sure and set the field of view to Wide, instead of Standard. This reduces the refractive distortions that cause this lack of sharpness, and the end results are much better. There is still some softness to the corners, but much further out to the sides of the frame.
This softness in the corners is not just a DJI thing. It happens with GoPro and other wide angle lenses that are used underwater without a housing. The water distorts the image, and actually makes it appear much less wide angle than the 155 degrees that this lens is. For GoPro you can buy some after market lenses that will restore the full width, and improve the overall sharpness of the image. It might be interesting to test some of those on the DJI. But suddenly things get much more expensive, and larger, when you start adding lenses.
Using the DJI Osmo Action 4 for snorkeling in the Wide setting, the 4K footage was really nice, and retains many more fine details than the 1080P setting.
Note though that the Wide field of view setting is not as wide as the standard, at 15mm vs. 12mm. Also a lens like this when used underwater will lose another 25% of its effective field of view because of the nature of how water refracts light. Just be aware your super wide angle lens will not be nearly as wide angle underwater. That is why some folks use auxiliary wide angle lenses with GoPro cameras to restore their field of view.
BEST UNDERWATER VIDEO SETTINGS FOR DJI OSMO ACTION 5 PRO
4K 60fps or 120fps
16:9
color normal 10bit (for non-grade)
color 10bit d-log M (for later grading)
rocksteady
FOV wide
Automatic white balance or white balance manual 5500K to match your Dive lights temperature
ISO 100-800 and leave shutter speed to auto, for manual the DJI Osmo Action 5 PRO the nearest settings are (1/100 - 1/8000) for photosomething between 1/125 and 1/160, with minimal settings 1/60 and maximum 1/250
At lower shutter speeds small movements of the camera with distort the image and fast moving objects wil create motion blur behind the subejct.
+0.0EV
sharpness -1
noise -1
front screen off
brightness 100%
turn off back screen to never
Wide and standard settings are nothing else then to crop the image and after that to stretch it to 4k resolution. So you will receive an overall worse image. Not only at the corners.
Rocksteady only works well with fast, smaller shocks. For example, when you are cycling or running.
You don't have that under water, so rocksteady is of absolutely no use.
What does help is horizon balancing, so you will receive a good aligned footage.

It's recommended by the filming and photography pro/experts and hobbyist divers around the world to use wide angle with actions cameras gopro/OSMO for underwater.
Gopro
Wide lens (16-34mm) use this for Underwater
Superview (16mm)
Hyperview (12mm)
Linear (Rectilinear 19-39mm)
Linear + Horizon Lock
Osmo action 4/5 pro
Standard (dewarp) at 15mm
Wide at 12mm use this forunderwater

This still doesn't change the fact that the image will be cropped and stretched.
However, it does mean that you can not undo it.
If you want good shots, you can do the cropping and stretching in post-production.

Full sensor of cameras on gopro is 8:7
in earlier models the sensor was practically 3840 horizontal pixels and cropping involved an actual decrease in resolution and subsequent upscaling to 4K.
Since the gopro 11, the sensor is 5.3K and even has an 8:7 or nearly square ratio. This means that 4K can be achieved by cropping but maintaining a 1:1 ratio of image pixels to sensor pixels.
The AOI lens is a good addition to GoPro gear. It offers sharper images, a wider field of view, and works perfectly with the 8:7 GoPro aspect ratio. After cropping, you can get great footage in both 16:9 and 9:16 formats.

Great to actually hear good advice from someone who knows what they’re talking about, believe me this guy who is pontificating I have seen his work and like you say movements cause blurred and out of focus images motion blur etc.
Uso ese lente con GoPro y la razón no es solo por recuperar anguló, sino por que permite acercarse al subjéto hasta 5 cm, algo que sin el lente es imposible, también mejora la nitidez y hay diferentes tipos de lentes no solo el angular, la marca INON ha lanzado varios tipos. Me estoy pensando pasarme a la Action 5 Pro porque por los análisis de las cámaras de la maraca GoPro y de DJI parece ser que esta ultima es superior en calidad de imagen. Por esa razón quiero informarme de todo lo que pueda sobre la Action 5 Pro y el tema del sensor de temperatura de color me interesa saberlo.
