I bought a K-3 at the begining of the semester, I've used it on one project so far and the first roll of film came back beautiful, the next four came back with no diffined frame lines makeing the images bleed together, creating a foggy look. This isn't what I was going for and was really upset. Then I found out about the lost loop thing. What causes this and how can I fix it? I like the camera and would like to try to repair and keep it. Does any one out there know how to help me? Matt-
