 Canon EF 16-35mm f/2.8L II USM lens : Canon releases its latest L-series EF lens for its new professional SLR, the EOS-1D Mark III. The EF 16-35mm f/2.8L II USM lens succeeds the versatile EF16-35mm f/2.8L USM lens as a high-performance L-series wide-angle zoom lens, specifically designed for improved peripheral image quality. This new EF series lens will meet the strict requirements of professional and high-end amateur photographers. Compatible with all EOS SLRs past and present, it uses three high-precision aspherical lens elements, each of a different type: ground, replica and GMo for even better image quality than the original EF 16-35mm f/2.8L USM.

Canon EF f/2.8L II USM lens
The circular aperture produces a beautiful and natural background blur when shooting at wider apertures. The Canon EF lens further uses two Ultra Low Dispersion (UD) lens elements to minimize lateral chromatic aberration and to produce superb image quality with excellent resolution and contrast. New coatings minimize ghosting and flare. It is an internal focus design, so the front element does not rotate during focusing and zooming, a convenience for users of circular polarizer filters. The lens is also fully gasketed and sealed for dust and moisture resistance, and it features an electronic diaphragm with circular blades for natural-looking background blur effects. Other features include internal focusing, a ring type USM (Ultra Sonic Monitor), and new AF algorithms for fast and quiet autofocusing.
