Sony DSC-P1 users take note:

Japan's Sony has said it is recalling its Cyber-shot DSC-P1, a popular range of digital cameras, due to battery defects.

The firm refused to say how many cameras would be affected worldwide but local media reported it had sold around half a million units.

Sony has received some reports of faulty charge level indicators or battery problems which shut down the camera.

It has asked customers to return the cameras for repair.
