used or refirbished?
Hi all, i'm thinking of buying the Canon 10-22mm lens used from kijiji. i'm worried that the owner originally bought it refirbished from Canon. is there a way to look up the serial number somewhere? or is it possible for something to be wrong with a lens, but it still takes pictures? in other words, you can use it and take pictures with it, but maybe the focus is off slightly or something else?
