Tiny dust flecks eventually find their way into a lens and can end up on 
the 2 lens surfaces that face the diaphragm.  It's possible they've been 
there a long time, seller couldn't see them or didn't look.  Clean is 
best, but they won't affect performance and I'll bet shipping had 
nothing to do with it.
