Versatile due to its mid-telephoto focal length and bright maximum aperture, the Canon EF 300mm f/2.8L IS II USM is also distinguished by its high-speed performance and intuitive handling to suit its use in a wide variety of working conditions. As an L-series lens, this tele prime of course features an advanced optical design; two fluorite elements are used to reduce color fringing and chromatic aberrations for high clarity and color accuracy and a Sub Wavelength Coating has been applied to individual elements to suppress flare and ghosting for increased contrast and color neutrality when working in backlit conditions. The fast f/2.8 maximum aperture also enables extensive control over depth of field for isolating subjects using selective focus, and it also benefits working in difficult lighting conditions.
