Just got into the hobby and new setup with a Nauticam A6600, Sony A6600 with a 10-18mm lens. I took it on a test dive today shooting video (4k/30fps) and trying to figure out how to avoid the Sony's focus hunting all the time. The lens I'm using does not have a manual focus gear available for the housing so not sure how to solve this as I would use MF if there was the option.
I set the focus to centre instead of wide as I was worried it would start to focus on other objects but the hunting is driving me mad. I'm going to test focusing normally and then using something like Focus Hold mapped to button to lock the focus, but this has it's own issues since if I move or the object does, then I cannot adjust.
Any tips would really help!
