Technical information[edit]

The EF 800 mm f/5.6L IS USM is a professional L series lens released June 2008. This lens is constructed with a magnesium alloy body and mount and with plastic extremities and switches. Features of this lens are: a wide rubber focus ring that is damped, a focus distance window, the ability to limit the focus range, a focus-preset mechanism, an image stabilizer that is effective up to four stops and is tripod sensing, an AF stop switch, and weather sealing. A maximum aperture of f/5.6 gives this lens the ability to create depth of field effects. The optical construction of this lens contains two fluorite lens elements, and "Super UD" (Ultra low dispersion) and UD Lens elements. This lens uses an inner focusing system powered by a ring type USM motor. This lens is compatible with the Canon Extender EF teleconverters.
