Here is a video I put together, it's a combination of 1080 (slowed to 50%), 4k and high frame rate (120 fps). Underwater white balance is really good down to 50-60 feet, which lets me get away with no filter or lights within that range. I work around the focus issues by pre-focussing using the back button focus lock and it seems to be fine in most situations (especially around f5.6). It seems to be fine on land though, only underwater, maybe it was the effect of the current/surge which was very strong. I did add some longer arms and float stix to help stabilize the footage in water as well. I did some testing with stabilization in post and it seems to resolve most of these issues, but it is an extra step. The only thing I'm knocking this camera for is the 4k video stabilization which could be better. Full setup includes 2 video lights, arms clamps, wet wide angle lens and it comes in at about 8-9 pounds and easily fits into a small backpack. I don't do stills, but for video I'd say it's almost perfect (for a smallish package). I have the LX10/Nauticam+vacuum valve (by nauticam, bought as a package). There are some LumaFusion limitations as well but for me it was worth the trade off of having an easily portable video editing machine that can handle anything I throw at it.
On the colour side if there is something I can’t do, I will do it in Resolve and import that LUT into LumaFusion. Now there are the usual apple limitations but I’ve worked around most of them I think. This thing cuts h.265 4k60 no problem and renders 100mbps projects in real time (up to 150mbps with the latest update). Now I’m using a 2018 iPad Pro 11” with LumaFusion as my video editor. This worked fine until I started using h.265 4k60, iMovie couldn’t keep up. Once completed, I export as ProRes and imported that video to DaVinci resolve for colour grading. My workaround was to use iMovie (which works very well with 4K) to build the timeline and sync my video to music. Having switched to 4K about 2 years ago I ran into limitations on the MacBook. I’ve been using a MacBook Air for the last 5 years. Most of my videos are travel related, both scuba and land based. As an alternative, here is my experience.
