In overall excellent condition. some very light coating scratches near the one side due to cleaning.
Most used lenses will have some amounts of internal dust as they are not hermetically sealed units! The action of focusing and zooming over time draws dust in some more than others. While it might be a unwelcome addition to a lens the impact to image quality is minimal if any.
Some light internal dust.
Fits all Pentax K AF DSLR crop sensor cameras
