There was a partially exposed roll in the Canon EOS 750 when I bought it in late 2014. I used the remainder of the roll as a test and, not expecting much, I had it processed at the drug store. Surprisingly, my shots came out pretty nice. There were also a few exposures from the previous owner.
Since the camera does pre-wind, these are probably in reverse-chronological order.
If you know these people or are these people, get a hold of me through the comments at my Youtube channel so I can send them a CD (kind of low-res since it’s drug store processing) and negatives.
I had to turn off comments on the blog after I was invaded by spam-bots.
