I had the chance to rent and use the NA-GH4 housing for a few dives to test it out. I'm on the fence and torn about the decision of buying one mainly because of the size of the housing. My problem is during custom white balance, and this is how I do it:
1.) Hand on right handle, using my index finger to trigger the WB menu
2.) Thumb press on the RIGHT cursor to select Custom WB, then UP to read WB, then SET to confirm WB.
When accessing the cursor area with my thumb, I can barely hold the right handle because my hand is not that big , and causing me to almost drop the housing a couple times
The question is, does anyone have success to operate the button one handed, by moving the handle bar a lot closer, or adding more float etc.?
I tend to use my left hand with a muck stick to stabilize on a sandy bottom or in between coral, and only operate the camera with my right hand, and I found the GH4 is hard to do so because of its size.
