I have a DSC-T9 that cannot focus on anything past 2 or 3 feet. Although when I take pictures from various distances, the aperture seems to change, as indicated in the viewing screen, but the pictures all come out equally blurry. Is this a problem with the focus lens motor? Or something else? Any help would be greatly appreciated.

Attached pictures shows : Portion of an outdoor picture from a year ago (NOT blurry), Portion of an outdoor picture from a few days ago(VERY blurry), Macro picture from a few days ago (NOT blurry).

Thanks in advance
