hi guys, a newbie here. just bought a 17-40L from a seller here. the condition is pretty good. just some light scratches on the body. optical quality is good as it shld be. however, i found out tt the lens is UT which means made in 2005. it's already 5 years since then. do u guys think it is ok? the lens being 5 years old already, i worry it may "break down".
sorry for the newbie qns.
