So, last week-end I took some pictures at a college graduation party for a niece. When I got home and reviewed them, they were all out of focus. I checked my E-PL6 and noticed that the autofocus wasn't working. I was using A mode all day with a Panny 12-32. Autofocus worked on the program modes, but not A, S and M. I kicked myself for not using P mode as usual. I have that set up to be shutter priority with some tweaks. I wrote to Olympus about it several days ago and have not heard back. Today I started playing with the camera again, diving into the menu looking for some kind of reset. I couldn't find any, but started playing around with the button assignments. When I got to the Fn2 button, I was confused. I couldn't find an Fn2 button on the camera. There was a function assigned to it (don't remember what it was). I decided to turn it off, since I couldn't find the button anyway. Then presto! autofocus is back to working in all modes! Where is this mysterious button and what is it supposed to do, other than crap up my autofocus?
