S9100 autofocus problem
That's a great camera, especially for that price. The only thing I can think of is that you are in a scene or mode that sets the focus to infinity. The camera had several quirks like that. Get very familiar with the owners manual especially the pages that show what settings are included or excluded in the various scenes and modes. There are some interesting features to play with that other cameras don't have and in fact were taken out of the newer models.
