The Canon EF 800mm f/5.6L IS USM is a top-of-the-line super telephoto lens and is the longest lens among Canon's lineup. Its aspherical, fluorite, UD and Super UD elements help to ensure extremely high-quality images while its ring USM auto focus system provides very fast auto focusing. Meanwhile, the EF 800mm f/5.6L IS USM's Super Spectra coating ensures an accurate colour balance.
The EF 800mm f/5.6L IS USM features four optical elements which improve image clarity: aspherical elements to correct spherical aberrations and refracting fluorite, UD and Super UD elements in order to eliminate chromatic aberrations for full edge-to-edge clarity. Its ring USM auto focus system provides the EF 800mm f/5.6L IS USM with very fast and precise auto focus that is virtually silent as it utilizes ultra sonic frequency vibrations while its full-time manual focus override allows the user to precisely adjust focus to taste. Additionally, the EF 800mm f/5.6L IS USM's Super Spectra lens coating suppresses flaring and ghosting by absorbing light reflected from internal lens elements for accurate colour balance and higher contrast images.
