Thank you

Most of the lens issues due to mechanical problem. some of the causes are dropping the camera.
Hard shake like keeping the Camera in the hand and jump through steps, Moisture condensation, Insufficient battery.. etc If If you feel that the issue is not with the above reason. Remove the battery, reinsert after 2 minutes to perform a power reset and check the operation.
If the issue persists, service may be required.
Thanks for understanding

Check for corroded or broken battery contacts.

problem in lens unit replace it

I had same problem and found out after leaving the battery out for an extended time (4 hours) it totally reset and worked. The initialize function on the camera did not work.

I had the same problem with the same camera, I took a pair of pliars and pulled on the the lens (pull it all the way out). Now it works again fine..Just like its supposed to..

Once you feed the date and time, it wont disturbed you again.
