Once you get closer than a certain point you will need to switch to Macro Mode on the camera - otherwise the lens will not focus correctly. Be sure to check in the manual what the distances are for normal or Macro photography. Also - once you are in that close you need a very steady hand - and/or a faster shutter speed if possible. Most likely you havent switched to Macro. - If Macro isn't available in Auto - try Program instead.
