Okay, maybe this is a stupid question, but I have seen it asked to many times in regards to a used lens for sale here..the manuf date/date code... In regards to lenses does it really matter. If it's a quality lens is it really that important. I would think things like is the glass free of marks etc...things that might effect image quality would be more important.
Is there a realistic reason why date codes should matter (outside of warranty issues)....am I missing something?
