For future reference (i am sure some others may find this post of some use if they stumble upon this lens of no information).
the lens works fine, a little bit of fungus didn't impair any of my shots, i have only tested it in pretty poor weather conditions (overcast, rainy, and actually flooding), so i am yet to really find out its true capabilities. But here is one of my first shots with it.
you may see its a bit soft at the top of the image - i don't believe thats an issue with the lens as its the only frame with such a thing in it, it might be the fog laying around the actual scene (it was misty) and/or the stupid lame people which scanned this shot.
From my other shots with this lens, it isn't all too bad, i hope to test its true capabilities soon when the weather clears up i can go out and about.
