Picked this up cheaply knowing it would be a cleaning project.



Fungus is pervasive. I am hoping this lens will be simpler than some of the other viv lenses like the 28-90 and 70-210's which often have structural complexity, and will be more like optical blocks in a tube.
Anyway does anyone have any prior experience with this lens?

There is a video on YouTube but it's behind a members only wall.
