As stated in the title, there is a dent on the zoom ring which does cause some minor resistance when zooming due to the rubbing/friction from the dent. There is also some minor damage on the filter ring which prevents filters from being attached.
The glass itself is in perfect condition with no visible scratches, haze or fungus. There is one tiny speck (about the size of the tip of a needle/pin) inside the rear glass element which doesn’t affect pictures.
The auto focus works great!
