The EF 28-300mm f/3.5-5.6L IS USM lens is a superzoom lens made by Canon Inc.

This lens has an EF type mount, that fits the Canon EOS line of cameras.

When used on a digital EOS body with a field of view compensation factor of 1.3x, such as the Canon EOS-1D Mark III, it provides a narrow field of view, equivalent to an 36-390mm lens mounted on a 35mm frame body. With a 1.6x body such as the Canon EOS 400D, it provides a narrower field of view, equivalent to an 45-480mm lens mounted on a 35mm frame body.[1]

This lens has a push-pull type zoom mechanism[2] and can be used for many types of photography, because of its large focal length range. It is used mostly for press photography, and also for travel photography.[3] [4]
