The EF 500mm lenses are a group of super-telephoto prime lenses made by Canon that share the same focal length.
These lenses have an EF type mount, and fit the Canon EOS line of digital single lens reflex cameras.
When used on a camera with a field of view compensation factor of 1.6x, such as the Canon EOS 400D, they provide a narrower field of view, equivalent to an 800 mm lens mounted on a 35mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III, they provide a less narrow field of view, equivalent to a 650mm lens mounted on a 35mm frame body.
These lenses are most commonly used by sports and wildlife photographers.
Three EF 500mm lenses have been available, and all are L series lenses. The most recent, the f/4L IS II, released in 2012 and is the only model in production.
