Had this lens for a while, decided to try it out, but discovered the aperture blades are stuck in the fully closed position. Anyone got any experience taking one of these apart to repair it? Looks different in construction to the later FL. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I've fiddled with the levers, to see if it needed cocking like the FD lenses, but not been able to get the blades to budge at all. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I don't think the blades are stuck, they look free of oil, I think it's the linkage, but I sense I'm going to have to take it apart to find out.
Spent all day taking an FD 100-300/5.6 apart to clean of fungus, only to find one of the innermost elements has been so badly etched it feels like it's corroded, rough, so a waste of time. Oh well. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |
