I was shooting with my friend last night, and he got the on his display and his camera refused to take anymore pictures. At first we thought it was an error, but upon looking it up online I saw that it was just the number of shots available in the buffer. However, no matter how long he let his camera sit, it was like the shutter was disabled somehow and wouldn't take the r06 off the display or let him shoot. A couple times if he waited and shook the camera it would let him take one shot, then it locked up again. He tried changing the file type from NEF to JPEG, switching camera cards, taking the lens on and off, and all to no avail. Has anyone else had this problem, and if so, how can one correct it?
