I have a possible trade pending and I would be receiving a Canon 135 L with a date code of US on it. When I look at the Sell forum I see the similar lenses with date codes of UX for the same value as determined in the trade I'm making.
My question is this, does the age of a lens matter once it is outside the warranty period? Will a lens, if not abused, with a datecode of US be the same as one with a UX?
Thanks!!!
