READ!!!

This lens is for all intents and purposes broken.  NO scratches on the front or rear element, no haze, no fungus.  You can take photos with it, it will auto focus fine, but it has front and back focusing issues that show up in the final image and will need to be serviced.  This is especially noticeable when shooting wide open and imperceptible to my eye when stopped down for wide angle landscape shots.  The focus ring is also no longer smooth while turning but still turns fine.  

Sold for parts, as is, no returns!!
