The issue of autofocus with the 4:3 cameras is that is is slow and sloppy however considering that the 7-14 has a minimum aperture of f/4 and the camera a 2x crop factor you can focus the camera on land at 3 feet, lock focus, jump in the water and you should have all in focus from 1.5 feet to infinity.
If instead you are shooting something closer or you zoom you have a problem and you need the camera to focus this is where manual focus is useful as autofocus as mentioned before is .....not that good
I do not agree here,
With my beloved old GH2 autofocus is fast as hell with 7-14mm. I tested hundred of times in really challenging conditions. IGH3 autofocus si still better than GH2.
On video you have to set spot focus, not multi point.
