To achieve AFL, try one of the followings
1. Set the camera in AF, half-press to lock focus, press OK and L and switch to MF. You
focus is now locked. To switch back to AF, press OK and R.
2. Set the Scene mode to underwater and press Down for Focus Lock. The camera will

photo in RAW because you cannot use Natural Color mode.

and basically ignore the iso setting all together and keep it at, say 100 or 200 and forget
about it. The only penalty might be that it is hard to use the lcd, but the benefit is that you
don't run the risk of clipping highlights the way the camera does when you set a higher
ISO number.

highlight protection in the software as you do this, you won't lose the highlights as you
would have had you let the camera clip them in the raw file.
I guess the way to use the camera with this strategy, would be to choose your aperture for
the DOF that you want. Choose the slowest shutter speed you can handle without blurring
so that you get the brightest exposure you can. Let the iso setting go up while
