Canon EF 16-35mm f2.8L III 120 So keep it folded downThis Canon EF 16 35mm f2. 8L III lens is a professional full frame ultrawide lens with Canon's premium L glass and construction, plus a fast f2. 8 constant aperture. Clean glass, excellent function. Worth noting: there is a very small ding in the edge of the zoom ring (pictured) which has no functional effect, but is definitely worthy of note. Otherwise, cosmetic condition is excellent. Includes hood.
