The EF 100-400mm f/4.5-5.6L IS II USM is a Canon EF-mount telephoto zoom for sports, wildlife and other distant subjects. Its rotating zoom ring has adjustable resistance, replacing the push-pull mechanism of the original lens.

It combines a fluorite element, a Super UD element and Air Sphere Coating with ring-USM autofocus. Three stabilization modes provide up to four stops of correction. The lens focuses as close as 0.98 m, reaches 0.31× magnification and includes a removable tripod foot.
