Lens is clean inside and out, there is not fungus or scratches on the the glass. The focus is nice and smooth.

Ok here is the catch... There is no aperture in the lens. There is physically no aperture mechanism in the lens. It is permanent on F1.8. This is how it came across my desk, I do not know the whys of this. The lens does take wonderful pictures, there are a bunch of sample pics included, and I can share more if you would like.
