Attached a little clip I've compiled from our dive trip to French Polynesia. I took my GH5s along this time but I did miss the stabilisation a bit I must admit...

 

Most shark footage form the Fakarava South Pass "Wall of Sharks" at Tomutoa Atoll.

Nice! Makes me want to book a ticket.... especially as it's grey and rainy outside.

The landscape land shots look great. Clearly the dynamic range is there.
For underwater shots did you do any slow down 30 to 24p or similar?
I cannot see any bumps from lack of stabiliser but surely you have trimmed them out or otherwise did you use any stabiliser in post as the footage looks good

Thanks! yes I shot in 30 resp. 60p put on a 24p timeline, I did some speed-up where the footage looked too slow. I did stabilize in post, which works amazingly well in Davinci. If you know where to look, there is some warping, but acceptable on the clips I used. There was a lot of footage which did not make my spec-test as the currents often knocked my camera around more than I liked....

Still, if you compare GH5 to GH5s footage, the inbody stabilization of the GH5 clearly shows.

Lens wise was this 8-18 or 7-14? The shots even close up look really wide
Colour looks accurate especially ambient light. Did you white balance or used K settings?
I believe the GH5 stabilisation is needed for wide angle when you have currents but still doesn’t fix everything

I was planning to use the 8-18 most of the time, particularly for the sharks, but it turned out that it was not narrow enough to get close-ups of single sharks. So I ended up using mostly the 12-35.

 

The WB is an interesting one. At depth (between 25 and 30m) the shots using manual WB in ambient light did not turn out that great. I ended up using auto WB and corrected in post. I am reasonably happy with the result. The blue of the Polynesian water is very intense and in most other clips you find on the net, the water looks purple, which I tried to avoid.  In shallower water, Auto WB gives very good results.

Yes I plan to use 12-60mm for sharks and general reef shots. For me 7-14 or 8-18 was never a consideration
What may happen here is that as the lens zoom is manual you can’t zoom quick enough as if you had the Power zoom lens.
For the white balance I think you may finish end of scale where the temperature is higher than 10000K and it goes out of range messing it up. After 25 meters even in clear water there appears to be too much blue!
I tried in the past colour temperature set to 9900K and choose the tint manually to avoid the too much magenta issue you mention but looks like auto and post adjustment works
Did you shoot vlog? Sorry for the in depth questions

No problem... Mostly Cinelike D, but some shots are V-Log. The 8-18 will be good for wrecks and of course I use it overland quite a bit. But the (considerable!) investment in zoom and focus-gear and that special step-up adapter required I almost regret....

Thank you for your time answering back. The 8-18mm could be good for stills if you take any

Thanks. The North Pass is also interesting but we got ripped apart by the currents, so it was not that much fun. South is usually more moderate and the sharks seem to like a slightly more relaxed style as well as they mostly gather there :)

Unfortunately, coral-wise the bleaching was really bad in most places we visited.
