Sorry - misread the original, so my original response is irrelevant.Having just recently taken some photos on my EOS 80D I found that when downloading to my PC that all but the last photo I had taken had disappeared. Is it possible that somehow my camera is overwriting the previous image?
It shouldn't be possible. If that really is happening, then either the card is faulty or the camera is faulty.Is it possible that somehow my camera is overwriting the previous image?
