Hey all, loaded a roll into my M6 the other day and the film advance started acting up. Seems to be fine just after I initially load the film in, but then once I close up the door and take a shot the advance lever becomes chunky to push forward and the film itself doesn't move, almost like it's not properly getting caught on the sprockets or something. Just started happening out of the blue with this roll and another I tried, nothing obvious that would have damaged it or anything. Any insight into what's going on here? I assume I'll just have to get it serviced.
