Out of interest seeing that the pz14-42 has focus at start of shot and you can refocus why would you need manual focus? Looks like autofocus works wonder for me
Ok, probably a 1000 different scenarios I can think of For example, you have focus locked on the eye of blenny, which is perfectly in your lower right power point. The fish moves and the eye is now in the lower left power point, still a great shot. If the gods are on your side and you are in focus tracking mode you may be ok. But they aren't, so you're not and the eye is out of focus. You can either re-establish focus and reframe your shot hoping the blenny doesn't move, or use the manual focus knob slightly and using peaking, get yourself back in business.
