Margaret I did mess with some of the settings but I don't think they did anything. In my reading, it seems there are other menus you go into to change the things I was trying to change.
Christine, that's a valid question but I did think of it & cleaned the lens with the cloth. it didn't seem to be smudged or dirty but I cleaned it anyway. I always keep a lens cover on it until I'm ready to shoot.
Maybe I need new glasses.
