a) fungus
b) oil on blades (not likely on this lens tho)
c) physical damage
Bring a small flashlight with you, shine light through other end and look inside for fungus, major scratches and dust. do not look directly into the light
There will be dust for sure because of the plastic construction, these should not affect image quality unless its a huge chunk.
There's a tab on the mount, flick it while looking inside; the aperture should open and close smoothly and blades align together. Run the zoom and focus a few times to test for smooth operation.
If possible, bring a camera to do some test shots. Take pictures of a everything and zoom in and out in your lcd to see for weird marks.
Do ALOT of research on market pricing and have fun.
