This copy had a small bit of internal fungus when I got it. I disassembled it and cleaned every element, removing all the fungus.
There is only the slightest impact to the coating on one side of one internal element.
The lens does have scratches on the body and glass, nothing uncommon for something this old.
Still it takes beautiful slightly dreamy photos and cleans up a lot as you stop down.
K&F m adapter included.
If interested I can also include 3 different Nikon Z adapters.
It can be hard to find info about this lens online
