This is the legendary Canon 70-200, which requires no introduction.
A workhorse of a lens, the Canon EF 70-200mm f/2.8L IS II USM is an L-series telephoto zoom characterized by its bright f/2.8 constant maximum aperture and optical image stabilization. The fast maximum aperture affords greater control over depth of field and benefits working in low-light conditions while the Image Stabilizer compensates for four stops of camera shake for sharper handheld shooting. As an L-series lens, this 70-200mm also features a sophisticated optical design that uses five ultra-low dispersion elements and one fluorite element to reduce color fringing and chromatic aberrations for improved clarity. Also, a Super Spectra coating has been applied to help reduce lens flare and ghosting for greater contrast and color neutrality.
