So I was outside today for a quick shoot it was about -16 degree celsius, I got through one roll of film and then couldn't shoot another picture, after changing film the camera kept saying starting app.. and would shut off and on again. the shutter wouldn't go at all. Very weird, I tried changing batteries and removing and replacing the lens, which didn't help at all. Also manually shutting of camera off and on again didn't work. I'm very surprised that such an expensive piece of gear couldn't work in the cold, although I guess the camera is meant for more studio use. Any ideas?
