I was shooting with my Canon 60D last night and the battery ran out. I switched to a fully charged spare, but got the following message: "Err 70. Shooting is not possible due to an error. Turn the camera off and on again or re-install the battery."
Turned it on and off, re-installed the spare, but still the same message. I charged the empty battery and re-installed it, same message again. Nothing extraordinary happened while shooting before the problem, the pics I took, up to the final one, were fine (downloaded them to my computer from the memory card). Any suggestions? The camera is about 18 months old. Thanks.
