Out of focus pictures

Out of focus pictures

I've cleaned the lenses and camera, tried 2 different Compact Flash cards, two different lenses, and tried numerous settings and lighting situations. I've updated the firmware, as well, but the situation remains. In every case, the camera appears to take the picture in focus but when I look at the saved photos, they are "fuzzy". When I look at the photos on the PC, they are "Fuzzy", as well. Any ideas?
