The RF mount design takes after the EF400mm f/2.8L IS III USM's excellent optics, which result in a lightweight lens with outstanding image quality. A super Ultra-low Dispersion (UD) lens and two fluorite lenses make imaging with high resolution and contrast possible. Offering high-quality images free of colour bleeding, this is Canon's flagship super-telephoto lens, perfect for professionals and advanced amateurs. Because of its small weight, photographers are able to capture breathtaking, high-quality images while being on the go. There is a switch on this lens that lets you choose between three different manual focus speeds. To keep the lens body from getting too hot when worn in the sun, it has a thermal barrier coating. On its own, the lens provides 5.5 stops of image stabilisation*.
