Today I was doing some fairly complex wiring on a multiple unit marine air conditioning system. THere were several terminal boards with a total of about 30 wires involved so I took digital pics of the wiring so I could refer to it. Interestingly, the pics I took using the VF3/flash/14-42 (at 42 and minimum focus distance)/shutter button were out of focus at the point I focused on in the VF; With everything else the same but switching to touch-shooting on the screen, the focus point was sharp. I repeated it a couple of times and the results were the same. Since my "focus" was on wiring, not camera stuff, I just cataloged it as interesting and whent on with the project. But I'm posting it here FWIW.
