Sick of buying lenses that need work
Zooms especially tend to collect dust inside. All the zooming in and out, is like a big piston sucking in air and dust. Small amounts should not be a problem. If there are piles of silt in there, well then... See post # 21 in this thread for how bad a lens can get, and still give a decent image.
