The simple answer to the above is No ! I bought the 14mm before the 10-24 mm came out . Using the 14mm around the streets of Rouen I wanted wider ! I've now got the 10-24 as well which at the wider end of the range is fantastic and close to the 14mm in quality . Shooting inside Cathedrals at 10mm , hand held at 1/10sec with the OIS is easily possible. ( Most venues ban tripods & Flash ) . So for Town, Cathedrals etc I'd use my 10-24mm- for landscapes etc the 14mm is superb. Team the 10-24 mm with an 18-55 or 18-135 and you have an awesome two Lens travel kit
