Yesterday I received 5d III. I got an extra battery too, Canon genuine (I ordered everything from B&H so no doubt in that).
This morning, as my first battery was about to get empty, I had swaped it with the other one and got cannot communicate error. I chose cancel and put the one that was at some 15% before back in.
For some reason I got the same error for that battery as well.
Now it seems that I have an issue with both batteries.
What should I do? I mean, it is a $3000 camera and the second day I used it...
Is this a firmware problem? The camera came with 1.1.3 Is there a way to reload it?
I cannot belive that once I finally got the camera I have to send it back.
Should I ask for a new one?
Is this acctually a battery or a camera problem?
