Is there a way to lock focus in AF-S to take multiple images to stitch, or can it only be done using manual focus?

In AF-S just keep the shutter half pressed. Focus point will remain green and you can move the camera.

But that's just for one shot, I think.  I need to be able to take multiple shots with the same focus point.  I'm not sure the Q3 can do that if AF-S acquires the initial focus point.  In other words, can the focus lock be mapped to a different button or does the shutter half press always reacquire focus?

I think the shutter half press retains the focus provided you don’t let it return up beyond half press after you’ve taken each image. Alternatively, switch to manual focus. Personally, when I’ve stitched images I’ve always used a small aperture so minor focus difference haven’t been an issue for me.
