Nikon F3 mirror is stuck after each trip of the shutter I am currently traveling in Cambodia and upon arrival the mirror was stuck up and so little else on the camera worked as well. I took off the lens and manually pulled it down. Then the meter worked and I hit the shutter button, and it seemed to work. However, when I advanced the lever, the mirror remains in the up position. Is there anything I can do to fix this?? Or do I need to find a repair center? Any ideas would be greatly appreciated!!
