Thank you for your help. I tried removing the battery (and recharging it) and replacing it. Then I reset it under set up. Hovever, it is still blurry.
By the way, the camera is a DMC-FX2
Is there a way of taking the lens out and cleaning it as that seems to be the trouble?
If not, I will need to take it to somewhere to be fixed. Do you know the Panasonic repair place in London?
All the best.
