Hi everyone, I am selling my Canon 17-35mm which is a superb lens. I bought this lens new and it still in mint condition. The focus is smooth and is perfectly working. When use the auto focus there isn't any faulty noises, it is fungus free and dust free. Am a photographer on myself, but because I am portrait oriented I have used this lens just few times. I am prudent and meticulous with my equipment, always take care, as I know how much this stuff is expensive!! This lens is great for landscape and architectural photography.
