Answers :

This can mean a host of different problems but try these things to fix it:\015\012\015\012
    \015\012
  1. clean the lense contacts as poor conection between the camera and the lenses can cause this. Also clean the contacts on the body of the camera.  The contacts should be cleaned with a plastic eraser, but make sure it is clean before using it.
  2. \015\012
  3. Clean the battery contacts (on the battery)
  4. \015\012
  5. Change lenses and see if you have the same problem (does it only have this problem on one lense?)
  6. \015\012
  7. Make sure you have the lates firmware installed.
\015\012Don't swap lenses while the camera is writing to the memory card, lots of things like this can cause this error message.\015\012Also the flash can cause it.\015\012
\015\012Usually the lense is the culprit so make sure it is fully cleaned.\015\012
