Canon 70-200mm f2.8L is ii USM

Canon has improved upon their long standing zoom lens with this model that features one fluorite and five UD elements for increased optical quality and reduced chromatic aberration. It holds a constant aperture of 2.8 throughout. Whether you're setting up an interview and want to push the background out of focus, or need those extra millimeters to shoot from far off, this is the lens for you. An industry standard.
