I have a Sony RX100 in a Nauticam RX100VII housing that I want to complement with a wide angle action cam for video shooting. Until now I used the Sony for video, too, but filming (in 4K!) drains its battery so fast that it sometimes didn't last till the end of the dive. Also, I would like to have a wider angle for filming, at least occasionally. I want to mount the action cam on top of the Nauticam housing so that I can take photos while shooting video.

Some time ago I read or saw something on the web saying that under water, the DJI is better than the GoPro. Unfortunately I don't remember why, or where I saw that. Therefore I want to ask here if anybody knows both systems and can make a recommendation. Or any tipps what to consider beyond the cam itself, like what kind of housings are available for each model (to use up to 60m deep), or which offers the better range of attachment lenses and filters.

No info on DJI but GoPro is decent. I moved from a Hero 7 to a Hero 13 last year. This year I added a wet lens and HF1 lights, but I haven’t used the new rig yet.

You should bring up the Insta360 AcePro2 on your radar. It‘s slightly more capable than the GoPro and the Osmo with the out of the box footage.

Personally I use Insta360 AcePro (version1) as a small secondary cam and that one already smokes the other cams around. Due to the larger sensor and leica optics of the insta you already notice slight performance differences in the underwater optics.

I have tested AOI, Backscatter and INON underwater action cam optics and found the INON image quality to be slightly superior than the others. There was also a thread here somewhere on the forums seconding my personal impressions about the superiority of the INON action camera optics.

I switched from GoPro to Osmo Action and never looked back. Much less noise, better colors, better low light quality, intuitive and quicker menus, 3 to 4 times longer battery life time, no crashes.

Whats the bitrate of Osmo action ?

Heres the bitrate on gopro 13 with labs firmware...

Dji Osmo action 6 from this video is looks inferior to Insta360 ace pro 2 released one year ago

The Osmo Action 6 loses focus and appears to have less detail

Looks like the Full sensor marketing of Dji Action6 dont keep their promises....

Fiming in 1:1 or 4:3 the imaged is cropped 

I cannot comment on Osmo Action 6, I got Version 5. I had several GoPros before and never will get one again based on above mentioned reasons. I don’t know AcePro but I remember that I read some not-so-great reviews during my research in order to decide between Osmo and AcePro. Both are likely to have their advantages.

To the best of my knowledge, action cams have fixed focus lenses and, therefore, cannot lose focus. Osmo Action has a larger sensor than others and therefore a larger minimum distance to take your footages.
