After upgrading my D7100 firmware, I've encountered quite a number of times getting this 'ERR' on my screen. My mirror just suddenly went half down during a photo shoot.This is very frustrating because this really disturbs my workflow and mood during events and stuff. (P.S. I am not using Mirror up mode ) Can this problem be solved by Nikon? Your feedback/reply is really appreciated!
