hello

I wanted to clean the lens because of fungus inside the glass . So based on various info from web , I dismount the lens from the bottom (indeed the rear of the lens ) as I could not find a way of opening it from the top. - nothing for a spanner wrench .
I unscrewed several rings and finally got to the lens cell ! But I can not go further .

Then I unscrewed two screws which holds the diaphragm's blades . The blades are dismounted and I can not put them back in place ???

I do not see how to move forward ! Does anyone have a solution? should I remove some ring frm the front ? how ?
If needed you can see the lens on B&H photovideo store searching keyword "NI2028" . thanks

please let me know ?

Daniel, this is a valuable lens , easy to ruin it if you don't have experience. Even if I have some experience , I send my valuable lens always to professional service.

Agreed. If you need help you should not be doing it.
