Went to the Bedford Butterfly house today. Finished one reel. Put another reel into the F80. Did not wind on properly. Next a, after half the reel burned, I got an error message on the camera. Thought it might be a battery problem. On and off , nope, change batteries, nope E is still flashing. Do a rewind. Only thing was that it did not seem to take long, if anytime at all. So being caution waited till I got home and removed film in the changing bag. Reel fully rewound. Checked cammera seems to work. I will put another reel in latter, and take a chance. Unless anyone has some cautious advice.
