I was using the latest release of the firmware but I have some issues with it and so I didn't feel it was stable enough, had a weird bug where I was viewing a image and it went static and disappeared then froze so I had to remove the battery. I then went and formatted the card on my PC and when I put the card back in the camera and pressed the menu button I just get a black screen and have to take the battery out etc. Everything else work though. Sometimes I get err 70 on the lcd but not always and err 70 seems unrelated to this issue.
Not sure what if anything I can do.
