 The EF 16-35mm f/2.8L II USM is a high performance, water-resistant, and ultra wide-angle Canon L-series lens. It has been specifically designed for improved edge-to-edge image quality that will meet the strict requirements of professional and high-end amateur photographers. It features 3 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. The circular aperture produces a beautiful and natural background blur when shooting at wider apertures. Other features include internal focusing, a ring type USM (Ultra Sonic Monitor), and new AF algorithms for fast and quiet autofocusing. Canon EF 16-35mm f/2.8L II USM from CameraWorld The professional’s ultra wide-angle zoom A fast, ultra wide-angle zoom lens offering excellent peripheral performance throughout the zoom range. With a constant f/2.8 aperture, it is ideal for professionals shooting in low light conditions. L-series quality The lens embodies Canon`s highest standards of L-series optics, build quality, reliability and operability. A robust construction includes dust and moisture resistant seals to protect against harsh weather conditions. Constant f/2.8 aperture A fast f/2.8 aperture delivers impressive low light performance and depth-of-field control. The aperture is fixed over the full focal range, allowing photographers to maintain a constant fast shutter speed when zooming. Fast, quiet auto focus A ring USM (Ultrasonic Motor) drives extremely rapid auto focus with near-silent operation. Full time mechanical manual focus override is available without having to switch out of AF. The lens offers a minimum focusing distance of 0.28m throughout the zoom range. Good background bokeh A circular barrel aperture helps to create attractive, even background bokeh when isolating subjects at wide apertures. UD and aspherical elements The EF 16-35mm f/2.8L II USM incorporates three aspherical elements to ensure corner-to-corner sharpness and clarity throughout the focal range. Two UD (Ultra Low Dispersion) elements virtually eliminate chromatic aberrations. Super Spectra coatings Super Spectra lens coatings suppress flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help maintain accurate colour balance and high contrast. Passes distance information to E-TTL II, the lens passes distance information back to the camera`s E-TTL II flash system for consistently accurate flash metering. Specifications
