Do you wear glasses? If so set the diopter on right side of the viewfinder. Focus your camera on a printed page until its in focus. Next move the diopter and see if the printed page becomes any clearer
Perhaps you could post an image so that the members might be better able to diagnose the "fuzzy" issue. I could be many things: focus issue, motion blur, camera shake, etc., etc.
What mode are u shooting in, check shutter speed and if u have IR on ur lenses make sure it is set correctly, and if ur old like me u make shake a little. HAHA
