OK as promised I have made a video with clips from my trip and each without FCPX editing, with stabilization, with rolling shutter and with both applied. You can see the differences and if stabilization and/or rolling shutter is good or not.

Actually I also don't have arm on the right side, so left hand on the arm and right hand on the housing. So for sure the front lens dial on the Recsea is not efficient. I hope Sony will have a firmware update to allow tweaking the sensitivity of the front dial so manual focus is more useful. Or maybe quick adjustment in normal view and fine adjustment in zoomed view?

In general I think to use a second hand controlling a front ring around the lens is not practical underwater. On a tray system with either 1 or 2 arms your second hand need to move quite far (either around the arm or underneath?) to get to the front ring to change settings then back to the handle before the shot for stability. Nauticam's little "knob" for the front dial make it easy as I can use my trigger index finger to move over to change and back to the trigger quickly.

Indeed I used the front dial for manual focus only, and when I really need to manual focus set it to closest focus range and move camera with focus peaking to get the focus point on my intended target. I only thought of this technique nearing the end of my trip so did not practice it much.

Another way to have better control on focus is to use tracking focus which by default is the center button. Then I can tell the camera where to keep in focus. Using manual focus in video is not that practical overall, as the front dial's "turn to effect" ratio as SPP has explained is too slow. Making A&S changes in manual with the rear dial and down button is easy and effective though.

I should have some spare time next week and I'll try to play around with the clips for more scrutinized comparison and share with you. Let me know if you have any specific way that you want me to test.
