On the other hand, some lenses are so bad, that even when they are brand new, they flare and loose all contrast at any hint of direct light.
So - if you do not like buying USED lenses that have not been in production for decades because they have defects that do not affect their operating quality, you should buy NEW lenses and leave everyone else alone.
