None I'm afraid, one of the unlucky 50 per cent

Thank you. I think I've found an answer by simply googling 'lens error', which I should have done in the first place. I'll copy it in case anyone else encounters the same difficulty

Oh dear! Well, thank you anyway. You haven't any idea I suppose of the probable cause?

I've had an optio E60 for longer than the warranty date. Suddenly, although the camera starts normally, within a few seconds it reads "lens error" and shuts down, without time to attempt any corrections. I expect this means there is some mechanical fault, but presently living in Portugal the only service available is in Barcelona and the shop where it was bought hasn't got a clue. Is it just possible anyone else has encountered this difficulty?

I think you're referring to a message which appears briefly before the camera shuts down? I have the same difficulty
