Hi everyone, I think I may well need the hand of some more experience photographer/DYI/lens repair people.
With the help of this
thread (and particularly from wavecurrent), I easily opened the lens and have complete access to the aperture blades.
Here is a picture of where I am at :
My problem is that the aperture blades are slow, but they don't seem to be oily or anything. If I close it down from wide open all the way to f/22, it can take a full second and sometimes will not close all the way.
So I figure the problem is simple enough, but since it doesn't seem to be grease on the apertures blades... I'm clueless. I would gladly listen to your suggestion.
Thank you in advance.
