Just wondered if anyone out there had the 16-35 which I use and bought the 14mm and loved/hated the prime? Im doing a lot of landscapes just now, love the zoom but im always shooting 16mm and wondered if you noticed any difference with the extra 2mm and any sharpness differences. I love my 16-35 but its a zoom, an excellent zoom, but as im always wide open that extra 2mm is tempting.
