Hi all,
My father gave me an old lens Tokina 80-200 f/4, but it was full of fungus. To start, this lens would not be that useful for me and, because of that, I decided to open it up and tried cleaning the lens.
I was not successful in this mission :'). Actually, I did screw everything back in, but the aperture is not working properly. As I said earlier, this lens isn't very useful for me, anyway, I want it to work like it used to  .
If I can't mount the lens again, that's ok, but if I succeed, it would be awesome.
There's a mini sphere that I don't know exactly where it belongs, cause it fells off as soon as I took the lens apart. You know where that sphere belongs and how I should mount again the rest of the lens correctly, so the aperture starts working again?
I will leave some images of me pointing to that sphere (#2) and the rest of the mechanism...

Thank you very much
