Canon EF 16-35mm f/2.8L ll USM Zoom Lens for Canon SLR Cameras. About this item: 16-35mm ultra-wide-angle zoom lens with f/2.8 maximum aperture 3 high-precision aspherical lens elements produce superior image quality. The Closest focusing distance: 0.92 feet A circular aperture produces natural background blur at wider apertures; a ring-type USM provides fast, quiet autofocusing; and internal focusing. Serious offers only, I won't sell it for $400 or $500. Thank you.
