My 7D has suddenly started playing up, when putting either of my geniune canon batteries in I get the flashing battery not reconised symbol flashing on the top screen, taking out & re-serting the battery will get the 7D to see it properly after a few attempts, but then if the camera in burst mode it will completely shut itself down!
The charger says both batteries are ok, and if I go to the camera menu and look at the battery info it states its OK?
Would this be anything to do with the backup battery or an actual fault with the camera?
Its running the latest firmware & ive not changed anything? Never used a battery grip either, if it needs to go in for repairs so be it, but don't wanna send it in for no reason....
I've tried googling & searching this site, found a few people with similar probs, but nothing to say what they actually found wrong/if it needed repairing?
Any help please?
