I wanted to write about an issue I experienced couple of days ago with my Canon Elan 7. I had a roll of 36 exposures in it and the battery run out of power just after I pressed the shutter to expose frame number 12. The shutter closed properly, but the film did not advance to the next frame and the camera went off completely. I changed batteries immediately, but all I got was the frame number on the LCD constantly blinking and the camera was unusable. I tried everything possible button or switch, but the only thing that worked was the mid-roll rewind. So more than half of the roll was left unexposed and I did not have a lead retriever with me. I was wondering if any of you experienced anything similar and if you know a way to bring the camera back to proper functioning in this situation.
