Thanks in advance to all! 1st trip abroad coming up (Paris). Canon Mark lll 5D My go to lens is Canon's 70-200 2.8 which I figure will serve me well there as it always does. Thinking of indoors (museums, etc)----would appreciate advice on a second lens to carry with me for low lights. Canon 85 1.2? Cost not a concern so open to all options. Thanks again!
