I've been shooting on GF670 with Tri-X 400 for the past weeks. Last Sunday I loaded a new roll that was bought on that day. As usual, when the arrow rest on the "6x6" indicator I closed my back and advance the film advance dial. In the middle it got stuck, I have to apply an extra force to make it finish the advance. I self developed this roll, and found it all the frame got shifted, the last frame only got half of the image. Also, the start of the film, on of the upper corner it folded a little triangle (approx 2mm side length).
I then load another new roll of Tri-X, it happened the same, got stuck when advancing the film during camera back closed. Again the film corner is folded too.
I got a bit suspicious this issue is come from the film itself, so I load a Ilford Delta 3200 to see if the problem replicates, strangely enough, no issue, smooth as it used to be.
I haven't exposed that Delta 3200 yet, but I would like to ask, particularly GF670 users, do you ever encounter this problem too? Please share your experiences. Thank you!
