I had error 20 last night on a shoot. This is the first time it has happened. Tried removing battery but made no difference to error.
Camera appeared fine until I took a photo and it then locked up. Strangely Live view was working fine and could shoot video and stills ok. Battery was showing as being over 50% full. When I got home I put the battery on charge. It started at flashing 1 light for a long time, seeming to indicate that the charge was very low and then slowly went through the sequence of flashes until it was fully charged.
Put battery back in camera and all seems to be ok now so I'm hoping that it is an error reporting charge on battery and not a camera fault as it is just over 6 months old.
