I am trying to reach the aperture mechanism of this lens. The aperture seems to have broken off and the blades open and close randomly when I turn the lens upside down. Something also rattles loudly inside. I don't know if that is the whole aperture mechanism or some parts that broke off. I manage to remove most of the rear part, including the mount and aperture dial. But I couldn't go beyond the zoom ring (where the orange marking "Macro" is written. I can see three screws inside (on the side actually) but they are covered by the zoom ring. I also remove the front element but can't go further to reach the aperture. Any guidance from the experienced ones is much appreciated. |
