I was playing around the other day with my E-PL2 in "A" mode on the dial and ran the F numbers (stops?) from 3.5 all the way to 22 to see if I noticed a difference compared to the iauto mode which settled on F9. I had my Camera on a tripod and F9 in iauto mode was the sharpest images always when shooting the same landscape scene. Is that normal? I though the higher the F number, the more balanced the detail would look everywhere. I did use center focus.
