Hey, photographic community. I dusted off the F80 recently and after a couple of rolls I started noticing some streaks on my negatives. Are those light leaks? If so - does anyone know what can be done on F80 to eliminate them? Internet says I should change the foam - but there's no foam. Like, at all. I don't think there's ever been any. I do not see any correlation, either. Some are long exposures, some are short and hand-held. Horizontal and vertical. But in almost every case there's this streak, it appears in the same place. Sometimes it's bigger, sometimes smaller, or not present at all. Some more are attached to the thread.
